► Spear & Jackson | Punches & Magnets

Precise Marking, Pin Work & Magnetic Retrieval

Small components can create surprisingly difficult workshop problems. Spear & Jackson punches & magnets bring together Eclipse tools for controlled marking, pin work, positioning & retrieving ferrous parts across mechanical maintenance, fabrication, engineering & general workshop applications.

Preparing a component before drilling or assembly? Measuring & Leveling Tools can help establish the correct position before a punch mark is made while Shop Presses & Vices provides workholding options where the component needs to remain secure during suitable workshop operations.

Choose by the task rather than treating every punch or magnet as interchangeable. A centre punch establishes a starting mark, pin punches work around pins & similar components while workshop magnets can retrieve, hold or position suitable ferrous material without performing any striking operation.

What Are Spear & Jackson Punches & Magnets?

Although punches & magnets perform very different jobs, both can solve the small positioning problems that slow workshop work down.

Within the broader Eclipse Professional Tools & Eclipse Magnetics ranges, relevant formats include:

► Centre punches
► Pin punches
► Automatic marking punches
► Punch sets
► Magnetic pick-up tools
► Hand-held magnetic retrieval tools
► Long-reach magnetic pick-up tools
► Pot magnets
► Bar magnets
► Button magnets
► Magnetic clamps

The correct choice depends on what needs to happen to the component. Marking a drilling point, driving a pin, retrieving a dropped bolt & holding a steel component in position require completely different tool designs.

Why Choose Spear & Jackson Punches & Magnets?

Precision becomes especially important when the component is small enough that a few millimetres can change the result.

Eclipse engineering punches provide purpose-specific options for marking & pin-related work while Eclipse Magnetics covers permanent magnets & workshop retrieval equipment for ferrous materials.

Depending on the individual product, applications can include:

► Marking drilling positions
► Pin removal
► Component location
► Engineering work
► Mechanical repairs
► Fabrication
► Workshop retrieval
► Recovering dropped ferrous components
► Jig positioning
► Fixture work
► General securing applications
► Maintenance tasks

Check the exact product before applying force or relying on magnetic holding. Punch diameter, tip geometry, operating method, magnet material, dimensions & magnetic performance vary between individual models.

Common Applications

Is the job about making a reference, moving a pin, finding a dropped component or holding ferrous material?

Punches & magnets can support:

► Workshop engineering
► Automotive servicing
► Machinery maintenance
► Fabrication
► Hole-position preparation
► Pin removal & installation
► Jig setup
► Fixture positioning
► Parts retrieval
► Stock-bin handling
► Cleaning up ferrous hardware
► General mechanical repairs

Separating those applications early prevents the wrong tool from reaching the workpiece. A marking punch isn't a substitute for a pin punch while a retrieval magnet shouldn't be confused with magnetic workholding equipment.

Product Selection Guide

Start with what needs to happen at the point of contact.

Tool type comes before size. Once the correct punch or magnetic format has been identified, compare its dimensions, capacity or magnetic characteristics against the actual application.

Centre Punches

A drill wandering away from its intended position can compromise the job before the hole has properly started.

Centre punches create a small indentation at a defined point on suitable material, giving the drilling operation a clearer starting reference.

Common uses include:

► Engineering layout
► Metal fabrication
► Workshop drilling
► Machinery repair
► Bracket preparation
► General maintenance

Establish the location accurately before creating the mark. A crisp punch mark in the wrong position is still an incorrect reference.

For finer dimensional checking before layout, Calipers (Digital / Manual) can complement general measuring tools around suitable components.

Automatic Centre & Marking Punches

Want a repeatable punch mark without reaching for a hammer? An automatic punch solves the operation differently.

The Eclipse EC-E172 automatic marking punch is hand-operated with an adjustable operating force specified by the manufacturer at 6.3–22.5kg.

Importantly, this model is specifically designed to operate without a hammer.

Potential applications include:

► Hole-position marking
► Workshop layout
► Engineering
► Fabrication
► Mechanical repairs
► Repetitive marking tasks

Don't strike an automatic punch simply because conventional punches are hammer-driven. Always follow the operating method specified for the individual tool.

Automatic vs Conventional Centre Punches

Both can establish a drilling reference but they create the mark differently.

Choose according to the mechanism as well as the material. Automatic & conventional punches shouldn't be treated as though their operating instructions are identical.

Pin Punches

Removing a pin cleanly starts with transferring force to the pin rather than the surrounding component.

Pin punches are used around suitable pins & similar components in mechanical, engineering & maintenance work.

Typical applications can include:

► Driving pins
► Removing pins
► Mechanical disassembly
► Machinery maintenance
► Automotive work
► Workshop repairs

Diameter selection is critical. A punch that doesn't correspond appropriately with the pin can slip, damage surrounding material or make controlled removal harder.

Choosing Punch Diameter

A small difference in punch size can create a large difference at the workpiece.

Before using a pin punch:

► Identify the pin
► Check its diameter
► Inspect surrounding clearance
► Select the appropriate punch size
► Support the component where necessary
► Confirm the pin has somewhere to travel

Measure instead of estimating when dimensions are uncertain. This is particularly important around smaller mechanical assemblies where adjacent surfaces can be easily marked.

Punches for Drilling Preparation

Good hole placement begins before the drill bit touches the material.

A practical preparation sequence can include:

► Establish a reference edge
► Measure the required position
► Mark the centre
► Verify the location
► Create the punch mark
► Secure the workpiece
► Select the correct drill
► Begin drilling under control

Don't use the punch mark to compensate for poor layout. Establishing the correct location first is what makes the indentation useful.

Punches for Mechanical Maintenance

Pins often perform simple jobs inside assemblies but can become awkward once wear, contamination or restricted access enters the picture.

Before driving a pin:

► Identify its direction of removal
► Check whether it is tapered or otherwise directional
► Support the surrounding component
► Match punch diameter
► Provide clearance behind the pin
► Keep the punch aligned

More striking force isn't always the answer when a pin refuses to move. Reassess the assembly, support, direction & possibility of corrosion or mechanical retention before escalating force.

For related repair hardware, Bolts & Fasteners supports suitable replacement & reassembly work once dismantling is complete.

Supporting the Workpiece

A punch can only transfer force effectively when the component underneath it is properly supported.

Suitable workholding can help:

► Reduce unwanted movement
► Improve punch alignment
► Protect surrounding components
► Keep hands away from the striking area
► Provide clearance for a moving pin

Support needs to suit the operation. A pin being driven out requires somewhere to go, so don't position the backing directly beneath its exit path.

Magnetic Pick-Up Tools

Dropped a steel nut into a place your fingers can't reach? Magnetic retrieval can turn an awkward search into a much simpler job.

Eclipse Magnetics produces hand-held magnetic pick-up tools designed to attract suitable ferrous items such as:

► Nuts
► Bolts
► Nails
► Screws
► Washers
► Small iron parts
► Steel components

Material matters more than appearance. Magnetic pick-up tools work with suitable ferrous materials & won't retrieve every metal simply because the component looks metallic.

Where recovered hardware needs replacement, Nuts & Washers provides related fastening components.

Hand-Held Magnetic Pick-Up Tools

Loose steel parts across a bench, floor or stock bin don't always justify picking them up individually.

Eclipse Magnetics hand-held retrieval tools use magnetic attraction to collect suitable ferrous items, with selected designs incorporating quick-release mechanisms to free the collected material.

A manufacturer-listed heavy-duty MPT185 model provides:

► Ferrite magnet
► Quick-release handle
► 185mm overall height
► 6kg listed pull force

Treat the pull-force figure as a specification for that model rather than every magnetic tool in the collection. Actual performance depends on the magnet & the conditions of contact.

Long-Reach Magnetic Pick-Up Tools

Retrieval becomes much more useful when the magnet can reach the floor or an awkward location without your hand following it.

The Eclipse Magnetics MPT700 long-reach model is designed for collecting & placing suitable ferrous items from ground-level locations.

Manufacturer-listed specifications include:

► 700mm height
► Ferrite magnetic system
► Quick-release handle
► 6kg listed pull force

Potential applications include:

► Workshop floors
► Maintenance areas
► Stock handling
► Hardware spills
► Collecting dropped fasteners
► General housekeeping

Long reach is primarily an access advantage. It doesn't mean every inaccessible component is safe or appropriate to retrieve magnetically.

Understanding Ferrous & Non-Ferrous Materials

Not every metal responds to a workshop magnet.

Magnetic pick-up equipment is intended for suitable ferrous materials such as many iron & steel components.

Common non-ferrous materials include:

► Aluminium
► Copper
► Brass
► Zinc

Test unfamiliar components rather than assuming attraction. Material grade, composition, shape, coating & contact conditions can all influence practical magnetic response.

Pot Magnets

When the application moves from retrieving loose hardware to positioning or securing a component, the magnet design changes with it.

Eclipse Magnetics produces shallow & deep pot magnets for applications including:

► Gripping
► Lifting
► Positioning jigs
► Soldering fixtures
► General securing
► Fixture work

Pot depth can influence where a magnet physically fits. Shallow designs can suit height-restricted applications while deeper formats may suit different fixture arrangements.

Alnico Magnets

Some workshop magnetic products are built around Alnico rather than the ferrite material used in selected pick-up tools.

The Eclipse Magnetics range includes Alnico:

► Pot magnets
► Button magnets
► Cylindrical bar magnets
► Pocket magnets
► Power magnets

Magnet material isn't a decorative specification. Different magnetic technologies are used across different applications, so product selection should be based on the manufacturer's stated purpose & performance data.

Button & Bar Magnets

Compact magnets often disappear into an assembly rather than being held like a conventional hand tool.

Current Eclipse Magnetics products include Alnico button & cylindrical bar magnets for specialised applications.

Manufacturer-listed uses across selected models include:

► Reed switches
► Hall effect sensors
► Electrical meters
► Circuit boards
► Security instruments
► Relay switches

These are specialised magnetic components rather than generic workshop retrieval tools. Check dimensions, material & application requirements carefully before selection.

Magnets for Jigs & Fixtures

Holding a small ferrous component in position can simplify assembly when the magnet is designed for that role.

Selected Eclipse pot magnets are specified for positioning jigs, soldering fixtures & general securing applications.

Potential considerations include:

► Component material
► Required holding performance
► Available space
► Magnet dimensions
► Contact area
► Operating environment

Don't substitute a retrieval magnet for engineered magnetic workholding without checking its intended application. Products that both contain magnets can still be designed for completely different tasks.

Magnetic Pull Force

A pull-force number only becomes useful when you know which exact magnet it belongs to.

Magnetic performance can be affected by factors such as:

► Magnet type
► Contact area
► Material
► Surface condition
► Air gaps
► Component geometry
► Direction of loading

Avoid treating the catalogue pull-force figure as a universal real-world lifting capacity. Use the manufacturer's data & application guidance for the specific magnetic product being considered.

Workshop Retrieval Around Machinery

The bolt that disappears beneath a machine can cost more time than the repair that caused it to fall.

Magnetic pick-up tools can help retrieve suitable ferrous components from accessible locations around:

► Workshop machinery
► Benches
► Vehicles
► Fabrication areas
► Maintenance spaces
► Storage bins

Check the environment before inserting a magnetic tool into machinery. Moving components, electrical systems, sensitive equipment & restricted areas can require additional precautions or another retrieval method.

For broader industrial maintenance context, Quarry Crews Crusher Maintenance explores the realities of equipment maintenance in demanding environments.

Punch & Magnet Safety

Small tools can still create flying debris, pinch points or unexpected movement.

Before working:

► Wear task-appropriate PPE
► Inspect punches for damage
► Check striking faces where applicable
► Keep hands clear of the impact zone
► Support the workpiece
► Follow automatic-punch operating instructions
► Confirm magnetic tools suit the environment
► Keep strong magnets away from unsuitable sensitive equipmen
► Don't rely on magnetic holding beyond the product's intended use

Personal Protective Equipment can support protection requirements around suitable workshop, maintenance & fabrication work.

Tool condition deserves attention before force is applied. Mushrooming, cracking, deformation or unreliable mechanisms should be investigated rather than ignored.

Caring for Punches & Magnetic Tools

Clean contact surfaces make inspection easier & help keep workshop tools ready for the next job.

After use:

► Remove swarf & debris
► Inspect punch tips
► Inspect striking ends where applicable
► Check automatic mechanisms
► Clean magnet contact surfaces
► Remove attached ferrous debris
► Test release mechanisms
► Store small components securely

Tool Storage & Organisation can help separate small engineering tools & magnetic equipment from loose workshop hardware.

Magnets are particularly good at collecting the debris you don't want on them. Remove attached swarf before storage so the working surface is ready for its next application.

Expert Tips

Mark Before You Drill

A drill bit is easier to guide when the intended centre has already been established.

Measure, verify then create the punch reference.

Don't Hammer an Automatic Punch

Internal spring-operated mechanisms are designed to create the marking action themselves.

Follow the individual manufacturer's instructions rather than treating every punch as a striking tool.

Match the Pin Punch to the Pin

Oversized or poorly aligned punches can contact the surrounding assembly instead of the component you're trying to move.

Check diameter & clearance before striking.

Give the Pin Somewhere to Go

Supporting the work directly beneath the exit point can stop the pin you're trying to remove.

Arrange workholding with clearance behind the pin.

Check the Metal Before Reaching With a Magnet

Aluminium, copper & brass won't suddenly become magnetic because they're difficult to retrieve.

Confirm the component is suitable for magnetic recovery.

Keep Magnetic Faces Clean

Steel swarf between the magnet & workpiece reduces clean contact.

Remove debris before positioning or retrieval.

Treat Pull Force as Product-Specific

One magnet's rating doesn't describe the entire range.

Check the specification for the exact model & intended application.
