One Case, The Hole Sizes That Cover Everyday Trade Work

Buying hole saws one diameter at a time makes sense for specialist work. For recurring installation jobs, it can leave the toolbox full of disconnected cutters, missing arbors & no sensible size progression. Starrett general purpose kits package selected hole saw diameters with the accessories needed to put them to work, giving electricians, builders, maintenance teams, installers & fabricators a more organised starting point for everyday hole cutting.

For jobs that extend beyond the supplied kit sizes, the broader Hole Saws & Arbors range makes it easier to add individual diameters, replacement arbors & related cutting equipment. Starrett also produces application-specific kit configurations where a more specialised group of hole sizes is required.

What Is A Starrett General Purpose Kit?

A general purpose kit brings together a practical selection of compatible hole saws & accessories for common cutting applications.

Rather than sourcing each component separately, selected Starrett kits combine multiple cutting diameters with the appropriate arbor, pilot drill & storage case. This gives tradespeople a coordinated system that is easier to transport, organise & keep ready for recurring installation or maintenance work.

The arbor provides the connection between the hole saw & power tool while the pilot drill establishes the cutting centre before the hole saw engages the material. Correct compatibility between these components is essential for controlled setup & reliable cutting performance.

That makes a complete kit particularly useful across:

► Building maintenance
► General construction
► Electrical installation
► Workshop fabrication
► Renovation
► Fit-out work
► Property maintenance
► Production engineering
► Installation work

The practical advantage is ready access to several useful cutting diameters within one organised system, reducing the need to assemble individual cutters & accessories for each new job.

General Purpose Doesn't Mean Every Hole Saw Cuts Every Material

This distinction matters.

Starrett manufactures different hole saw constructions because cutting timber is not the same job as cutting stainless steel, masonry, ceramic tile or abrasive building materials.

Depending on the exact kit family, Starrett offers technologies including:

► Bi-metal hole saws
► Tungsten carbide tipped hole saws
► Diamond grit hole saws
► Mixed-technology kits

Before choosing a kit, ask:

What materials will these cutters encounter most often?

That question is more useful than buying on the number of pieces alone.

Bi-Metal Or Carbide Tipped – Start With The Material

Two general-purpose kits can look similar in a case while behaving very differently at the cutting edge.

The cutter should be matched to the substrate.

Using a more expensive hole saw does not automatically make it the correct hole saw.

Starrett Multi-Purpose Carbide Kits – Built Around Material Variety

Starrett's TCT Fast Cut Multi-Purpose hole saws are designed for rapid cutting across a broad range of compatible construction materials.

Starrett identifies applications including:

► Wood
► MDF
► Plastics
► Building brick
► Ceramic tile

The cutters use tungsten carbide tipped teeth plus a tooth form intended for aggressive stock removal.

That makes a multi-purpose carbide kit particularly interesting for builders, maintenance technicians & installers who may encounter several different substrates during the same working week.

It is a very different buying proposition from a kit intended mainly for metalworking.

A Practical Example – The KMP03031-N General Purpose Kit

One Starrett general-purpose configuration is the KMP03031-N, a six-piece multi-purpose carbide tipped hole saw kit.

The set includes three hole saw sizes:

► 54 mm / 2-1/8"
► 65 mm / 2-9/16"
► 92 mm / 3-5/8"

along with:

► A2-E arbor with carbide tipped pilot drill
► Two XA014C carbide tipped pilot drills
► Carrying case

Starrett specifies an approximate 54–92 mm hole-size range for this configuration.

That makes the kit worth considering when those larger installation diameters align with the work being performed.

The important lesson is not that these three sizes suit every trade.

It's that kit contents should match the holes you repeatedly cut.

Don't Buy By Piece Count

A “six-piece kit” can sound better than a “five-piece kit”.

Until you examine what the pieces actually are.

Kit counts may include:

► Hole saws
► Arbors
► Pilot drills
► Replacement pilot drills
► Accessories

So compare the number of useful cutting diameters first, then check the arbor configuration, included pilot drills & replacement accessories.

A kit with four regularly used cutting sizes can deliver more practical value than a larger set where several diameters rarely leave the case.

Builders & Renovators – Material Changes Are The Real Challenge

Renovation work is unpredictable.

One penetration might pass through timber.

The next may involve sheet material.

Another may meet masonry or tile.

That makes material compatibility particularly important for builders choosing a general-purpose hole saw kit.

Typical jobs can include:

► Pipe penetrations
► Cable access
► Downlight or fitting preparation
► Ventilation openings
► Cabinet penetrations
► Building-service access
► Retrofit work

A kit reduces the number of individual cutters floating around the vehicle, but the cutter technology still needs to match the material in front of you.

For the drill platform powering those cuts, Heavy-Duty Power Tools provides a relevant supporting range.

Maintenance Teams – The Hole Size You Didn't Expect Is Usually The One You Need

Scheduled fabrication is predictable.

Breakdown work often isn't.

A maintenance technician may arrive expecting to enlarge a cable opening then discover the replacement component requires a completely different penetration.

Keeping several useful hole saw diameters together can reduce trips back to the workshop.

A general-purpose kit can support tasks around:

► Equipment modification
► Control enclosures
► Replacement component installation
► Guards
► Panels
► Building services
► Workshop improvements
► Plant repairs

For metal preparation around repair plus fabrication work, Metal Cutting & Grinding Tools complements the cutting side of the kit.

Electricians – Check The Sizes Against The Fittings You Actually Install

An electrician does not need a collection of impressive hole saw diameters.

They need the sizes that match real installation work.

Before buying, look at the components used regularly:

► Conduit
► Cable glands
► Junction hardware
► Enclosures
► Fittings
► Switchboard components
► Cable access requirements

Then compare those needs with the diameters supplied in the kit.

For the surrounding installation workflow, Wiring & Connectors provides a natural next step.

A well-selected kit should reduce improvisation—not create another case full of sizes that almost fit.

Arbor Compatibility Deserves As Much Attention As Diameter

The hole saw does the cutting.

The arbor provides the mechanical connection between the cutter & drill while supporting the pilot drill used to establish the cutting centre.

When adding or replacing a Starrett hole saw, check:

► Hole saw connection
► Arbor type
► Hole saw diameter
► Pilot drill type
► Drill chuck capacity
► Intended material
► Existing kit components

Never assume every Starrett cutter uses the same arbor merely because the brand name matches.

What Does The Pilot Drill Do?

Before the hole saw's cutting edge establishes the circular cut, the pilot drill locates the tool at the intended centre point & helps stabilise the start of the cut.

That makes accurate marking important.

A poorly positioned pilot hole means the finished opening will also be poorly positioned.

Mark the required centre accurately, confirm clearance around & behind the workpiece, fit the correct arbor plus pilot drill then establish the pilot before bringing the hole saw progressively into the material.

For setting out hole centres before cutting, Measuring & Layout Tools supports the preparation side of the job.

Check Behind The Surface Before You Pull The Trigger

The visible face of a wall, panel or board tells you very little about what is behind it.

Before cutting, consider:

► Electrical services
► Pipework
► Structural members
► Hidden fasteners
► Insulation
► Finished surfaces on the opposite side
► Required cutting depth
► Available drill clearance

A hole saw is designed to remove material efficiently.

It cannot distinguish between the material you intend to cut & the service you did not know was there.

Speed Matters – Faster Isn't Always Faster

Running a hole saw at excessive rotational speed can increase heat plus reduce cutter life.

The appropriate drill speed depends on:

► Hole saw diameter
► Cutter construction
► Workpiece material
► Cutting conditions

As cutter diameter increases, the appropriate rotational speed can change significantly.

Follow the current Starrett operating guidance for the exact cutter plus material being used rather than assuming one drill setting suits every hole saw in the case.

Efficient cutting comes from matching the cutter, speed plus feed to the work—not simply running the drill at maximum speed.

Let The Cutter Work

Heavy pressure can feel productive.

It can also create heat, increase drill load plus make the cut harder to control.

Start the pilot accurately.

Bring the cutting teeth into contact in a controlled manner.

Maintain suitable feed pressure.

Clear chips where the application requires it.

If cutting performance suddenly deteriorates, investigate:

► Tooth condition
► Material suitability
► Drill speed
► Chip accumulation
► Pilot condition
► Workpiece movement

More force is not automatically the solution.

What About Cutting Metal?

For compatible hole saws, secure workholding becomes especially important.

Loose sheet or components can move when the cutter engages.

That can damage:

► Workpiece
► Cutter
► Pilot drill
► Drill
► Finished opening

Where practical, clamp the work securely rather than trying to restrain it by hand.

Clamps & Vises provides a useful supporting range for workshop cutting setups.

Always match the hole saw, speed plus cutting method to the particular metal being worked.

Keep The Arbor With The Kit

One of the easiest ways to turn a useful hole saw kit into an unusable one is to separate its arbor from the case.

The same applies to pilot drills.

After use:

► Remove chips
► Inspect cutting teeth
► Check the pilot drill
► Return the arbor to its position
► Replace missing accessories
► Store cutters securely
► Keep the case dry

A five-minute reset after the job is easier than discovering a missing arbor on the next site.

For other Starrett equipment that benefits from dedicated protection between jobs, Starrett | Tool Storage & Cases provides a closely related storage pathway.

Kit Or Individual Hole Saws – Which Makes More Sense?

Choose a kit when:

► Several hole diameters recur in your work
► You need a ready-to-carry setup
► Arbor plus pilot compatibility needs to stay organised
► Different jobs regularly require different sizes
► You are building a hole-cutting setup from scratch

Buy individual cutters when:

► One diameter dominates the work
► You already own the correct arbor
► You are replacing a worn cutter
► You need a specialist diameter not included in a kit
► You are extending an existing set

There is no advantage in buying duplicate tooling simply because it comes in a case.

Build The Kit Around The Work You Invoice

A useful general-purpose kit should reflect paid work rather than theoretical versatility.

Look at the last month of jobs.

Which hole diameters were actually used?

Which materials appeared repeatedly?

Which cutter had to be borrowed?

Which arbor went missing?

Which specialist size forced an extra supplier trip?

Those answers tell you more about the right kit than the largest piece count on the shelf.

For tradespeople reviewing what belongs in a practical working kit, The Apprentice's First Tool Kit: What You Actually Need takes the same task-first approach to tool selection.

Expert Tips For Getting More From A Hole Saw Kit

Write the common sizes inside the case. You'll know immediately whether the kit covers the next job.

Check material before choosing the cutter. “General purpose” does not remove material limitations.

Keep the correct arbor in the case. A complete kit should remain complete.

Inspect the pilot drill first. A damaged pilot can compromise positioning before the saw starts cutting.

Mark the centre accurately. The pilot follows the mark you give it.

Adjust speed for diameter plus material. Maximum drill speed is rarely a universal setting.

Secure loose workpieces. Especially when cutting sheet, panels or smaller components.

Replace worn cutters individually. A blunt hole saw does not mean the entire kit has reached the end of its life.

For workshops preparing equipment before a busy period, Spring Jobsite Prep Getting Your Gear Ready is particularly relevant to checking cutters, pilots, arbors plus cases before the next job exposes what's missing.

The Case Has Value Only If The Tools Come Back To It

The biggest advantage of a kit can disappear through poor tool discipline.

One hole saw ends up in the drill box.

The arbor stays on a bench.

A pilot drill gets borrowed.

Suddenly the “complete kit” is three unrelated cutters plus an empty slot.

A tool is not just a tool. It’s a promise. is a useful reminder that professional equipment delivers its value through the way it is selected, maintained plus used.
