Reliable Threading for Workshop & Site Pipework

Need clean, repeatable threads without turning pipe preparation into a drawn-out manual job? Garrick Herbert Pipe Threading Machines bring ASADA professional threading equipment, dieheads, dies & threading consumables together for plumbing, mechanical services, fire services, fabrication, maintenance & industrial pipework.

From compact threading requirements through to larger-diameter workshop work, ASADA machines provide purpose-built options for cutting compatible pipe threads efficiently. Model choice should start with the pipe diameter, thread standard, material & frequency of work, followed by the correct diehead, dies & cutting oil for the application.

Pipe preparation rarely starts at the thread. Garrick Herbert | Pipe Saws provides portable cutting for suitable steel & stainless pipe, Garrick Herbert | Roller Stands supports longer pipe around the working area, while Garrick Herbert | Pipe & Bolt Threading covers complementary threading equipment across the broader range.

Cut the pipe to length, support it correctly & match the threading setup to the connection that needs to be made.

What Are Garrick Herbert Pipe Threading Machines?

Pipe threading machines cut external threads onto compatible pipe so it can be assembled with threaded fittings, valves & other suitable components.

ASADA machines combine pipe holding, powered rotation & compatible dieheads into a dedicated threading station. Depending on the machine & setup, related pipe preparation functions can also form part of the working process.

The Garrick Herbert range includes equipment & consumables such as:

► ASADA pipe threading machines
► Manual dieheads
► Automatic dieheads
► Alloy threading dies
► HSS dies for applicable materials
► BSPT & NPT threading options
► Threading oil
► Replacement components
► Compatible pipe-preparation equipment

Different machines accept different dieheads & die sets, so compatibility should be confirmed by machine model, pipe size & required thread form before equipment or replacements are selected.

Why Choose ASADA Pipe Threading Machines?

One threaded joint may be straightforward. A day of pipe preparation changes the equation.

Powered threading equipment provides a dedicated setup for workshops & trade operations where threaded pipe forms a regular part of installation, fabrication or maintenance work.

Common applications include:

► Commercial plumbing
► Mechanical services
► Fire-service pipework
► Industrial maintenance
► Plant-room installations
► Workshop pipe fabrication
► Building services
► Steel pipe preparation
► Equipment repairs
► Repeated threaded connections

Purpose-built machinery also brings the pipe holding, threading action & compatible tooling together at one workstation rather than treating each thread as an isolated hand operation.

Common Applications

Commercial Plumbing

A threaded connection begins well before the fitting is tightened.

Pipe must be measured, cut to the required length, prepared & threaded correctly for the connection being assembled. Where multiple threaded lengths are being produced, a dedicated machine provides a practical preparation station.

Keep finished dimensions in mind before cutting stock. Thread engagement & subsequent assembly can affect the length required from the finished component.

Mechanical Services

Plant rooms can contain pumps, valves, gauges & pipe assemblies where threaded connections remain an important part of installation & maintenance.

A workshop threading setup allows suitable pipe sections to be prepared before they reach the installation area, while portable equipment can support work that needs to happen closer to the existing system.

Fire-Service Pipework

Repeated pipe sizes can make organisation just as important as machine capability.

When preparing multiple lengths, separate stock by diameter & finished length, keep the required dies clearly identified & verify the first completed thread before continuing through a batch.

Applicable project specifications, standards & installation requirements should always govern the finished pipework.

Industrial Maintenance

Replacement pipe often needs to fit equipment that's already there.

Maintenance work may involve reproducing a damaged section, modifying an existing line or preparing a new threaded component to suit an established installation.

Measure the complete assembly rather than copying only the removed pipe length. Previous repairs or fittings can affect what the replacement actually requires.

Fabrication Workshops

Pipe preparation can sit alongside cutting, welding & general metalworking within the same workshop.

A dedicated threading station keeps suitable threaded work separate from fabrication processes better handled by saws, welders or grinders.

Where the connection will be welded rather than threaded, choose the preparation method around the final assembly instead of adding a thread that isn't required.

ASADA Pipe Threading Machine Selection Guide

The largest machine isn't automatically the right machine.

Start With Pipe Diameter

Regular pipe size should be the first filter.

A machine working mainly on smaller service pipe has a different requirement from a workshop routinely preparing larger industrial pipe. Check both the minimum & maximum capacities of the specific model.

Confirm The Thread Standard

Thread diameter alone doesn't define the finished thread.

ASADA tooling is available across thread forms including BSPT & NPT, with additional threading systems available elsewhere across the broader Garrick range.

Confirm the required standard before selecting dies or dieheads.

Identify The Pipe Material

Black steel, galvanised pipe, stainless steel & higher-strength materials can place different demands on threading tooling.

Garrick lists alloy dies for general-purpose threading such as black or galvanised pipe, while HSS options are available for stainless & high-tensile steels.

Match the tooling to the material rather than treating every pipe as the same cutting job.

Consider Work Frequency

How often will the machine actually be threading?

Occasional workshop preparation, regular service work & continuous pipe fabrication place different demands on equipment, tooling & consumable availability.

Plan For Consumables

Dies & cutting oil are working parts of the threading process.

Keeping the correct replacements available is particularly important where the machine supports daily pipe fabrication or installation work.

ASADA Dieheads & Dies – Compatibility Matters

A diehead that fits one machine shouldn't automatically be assumed to suit another.

ASADA provides different dieheads across compatible machine families, including options for common pipe-threading ranges such as:

► 1/4"–3/8" BSPT & NPT manual threading
► 1/2"–2" BSPT & NPT manual threading
► 1/2"–2" BSPT automatic threading
► Larger automatic BSPT applications on compatible machines
► Metric bolt-threading dieheads on applicable pipe machines

Before ordering replacement tooling, record:

Machine model → Pipe diameter → Thread form → Diehead → Die specification

That sequence is considerably safer than trying to identify dies by appearance.

For additional hand & portable threading requirements, Threading Tools provides complementary equipment for suitable pipe-thread preparation.

Alloy vs HSS Threading Dies

Material matters at the cutting edge.

Garrick specifies alloy dies for general-purpose applications such as black or galvanised pipe & rod, with HSS dies available for stainless & high-tensile materials.

Always confirm the die specification against the material & machine before threading.

Why Threading Oil Matters?

The dies are cutting metal every time a thread is produced.

Suitable threading oil assists the cutting process & can have a significant effect on die life. Garrick specifically notes that die life is greatly affected by cutting-oil quality & recommends ASADA Threading Oil with its threading equipment.

ASADA neat threading oil is available in:

► Standard 5L
► Standard 20L
► High-grade 5L

Use the oil specified for the machine, tooling & material being processed.

This isn't the place to substitute an unrelated workshop lubricant simply because it's already on the shelf.

Pipe Threading Machine vs Portable Power Threader

Where the work happens can matter as much as pipe size.

A fixed machine makes sense when pipe repeatedly comes to the threading station.

Portable threading equipment becomes useful when the work needs to follow the pipe.

Choose around the working environment rather than assuming portability or machine size automatically makes one approach better.

Supporting Long Pipe At The Machine

A secure chuck doesn't support the entire length of the workpiece.

Long pipe extending beyond the threading station needs an appropriate support arrangement so it can approach the machine at the required height without unnecessary sag or instability.

Before starting, consider:

► Pipe length
► Pipe weight
► Machine working height
► Support position
► Clear infeed area
► Clear outfeed area
► Operator access
► Finished-piece handling

The RS-V configuration in Garrick's roller stand range is specifically intended for applications involving threading machines, pipe & rod.

For heavier stock that also needs moving around the workshop, Material Handling Equipment provides complementary equipment for suitable lifting, moving & positioning tasks.

From Pipe Length To Threaded Component

Good threads depend on the preparation that happens before them.

A practical sequence is:

Measure → Mark → Support → Cut → Prepare → Thread → Inspect → Assemble

Skipping attention at an earlier stage can create problems later.

Measure With The Connection In Mind

Don't treat the raw cut length as the finished assembly dimension.

Consider the fitting, required engagement & applicable pipework specification before establishing the component length.

Make A Suitable Cut

The end being threaded needs appropriate preparation for the threading process.

Where portable cutting is required, Garrick's ASADA pipe-saw equipment provides an option for suitable steel & stainless pipe.

Support The Workpiece

Long material should approach the machine correctly rather than relying on the threading-machine chuck to deal with the unsupported length.

Match The Tooling

Confirm thread form, pipe size, material & die compatibility before starting.

Inspect The Result

Check the completed thread against the applicable requirements before repeating the setup across additional pipe lengths.

Threading Pipe vs Threading Rod & Bolts

They may both require external threads, but the equipment isn't necessarily interchangeable.

ASADA's BTM25 Rod/Bolt Threading Machine is a dedicated machine specifically designed for bolt & rod. It uses a faster spindle speed than ASADA pipe-threading machines & holds rod in a vice to accommodate long lengths or bent material.

The BTM25 provides a standard threading capacity of 8–24mm, uses a 1140W / 1.5HP single-phase motor & operates at 80rpm no-load speed.

Thread forms across the broader die range include:

► BSPT
► NPT
► BSPS
► Conduit
► BSW
► Metric
► UNC
► UNF

For pipework, use equipment & tooling intended for the pipe-threading operation. For dedicated rod or bolt production, a purpose-built rod/bolt machine can provide a more appropriate setup.

Preparing Threads For Fabricated Assemblies

Not every workshop pipe assembly follows the same joining method.

Some components rely on threaded fittings. Others move into welded fabrication or a combination of processes depending on the system being produced.

Where welding forms part of the assembly, How to Choose the Right Welding Machine for Your Fabrication Shop provides practical guidance for matching welding equipment to the material, process & workshop requirements.

For post-cut preparation elsewhere in the fabrication process, Metal Cutting & Grinding Tools provides complementary equipment for suitable grinding & metal preparation work.

Workshop Setup Around A Threading Machine

The machine footprint tells only part of the story.

A threading station also needs enough room for the pipe itself, tooling, consumables & normal operator movement.

Plan space for:

► Long pipe entering the machine
► Finished pipe leaving the station
► Roller support
► Diehead changes
► Die storage
► Threading oil
► Cleaning
► Routine inspection
► Offcut handling
► Operator access

Positioning a machine neatly against a wall is little help if the regular pipe length can't reach it.

Keeping Dies & Equipment Ready

A poor thread can begin with a worn cutting edge.

Inspect dies according to the manufacturer's guidance & pay attention to changes in normal threading performance. Cutting quality, increased effort or changes in the finished thread can indicate that the tooling, lubrication or setup needs attention.

Practical workshop habits include:

► Keep die sets identified by size & thread form
► Store dieheads where cutting edges are protected
► Use appropriate threading oil
► Keep the machine clean
► Check tooling before repeated work
► Replace damaged or unsuitable dies
► Follow machine maintenance requirements

Expert Tips

Identify the thread before selecting the dies. Diameter alone isn't enough; confirm BSPT, NPT or the applicable thread form.

Match die material to the pipe. General-purpose alloy dies & HSS options serve different material requirements.

Use proper threading oil. Lubrication directly affects the cutting process & can influence die life.

Support long pipe independently. Don't expect the machine chuck to manage metres of unsupported stock.

Check the first finished thread. Confirm the result before repeating the setup across a run of pipe.

Keep die sets clearly labelled. Machine model, thread type & size should be immediately identifiable.

Plan the finished assembly before cutting. Thread engagement & fittings can affect the required pipe length.

Use purpose-built equipment for rod work. Dedicated bolt & rod threading can require a different machine configuration from pipe threading.
