Speed and Efficiency: Hole saws allow for quick and efficient hole cutting, making them ideal for projects that require multiple holes.
Clean and Precise Cuts: With sharp teeth and a well-designed cutting profile, hole saws produce clean and accurate holes, reducing the need for additional finishing work.
Versatility: Hole saws are compatible with different materials, making them a go-to tool for a wide range of applications.
Interchangeable Bits: The ability to swap out hole saw bits on the same arbor allows for flexibility in hole sizes, maximizing efficiency during various tasks.
Cost-Effectiveness: Hole saws are relatively affordable and provide a cost-effective solution for hole cutting compared to other cutting tools.
Type of Electroplate Diamond Hole Saw
Bi-metal Hole Saws : The most common Hole Saw Tool, this is typically constructed from stainless-steel material and can tackle most materials and most projects. Due to their robust structure, these hole saws can handle the most heavy duty tasks and projects. Suitable for unalloyed steel (up to 700 N/mm² strength), non-ferrous and light metals, plastics, tiling, plasterboard and light building boards, fibreboard, plywood and wood.
Tungsten Carbide Hole Saws: Ideal for Metal Cutting, these Hole Saw tools are strong and powerful, delivering a fast and aggressive hole cutting process. Shallow Cut TC Hole Saws are equipped for steel thickness up to 2.0mm and plastics up to 4.0mm, whilst Multigrade TC Hole Saws can handle up to 20.0mm of steel and 28.0mm plastic thickness.
Carbon Steel Hole Saws : Suitable for electrical and plumbing based applications, these hole saw cutters are ideal for handling lighter materials such as plasterboards. This is due to their less durable material in comparison to Bi-metal Hole Saws for example, thus making them more for home diy improvements and light duty activities. However, due to their durability, they can offer the perfect tool for the weaker more fragile materials which require a hole cut.
Welded Shank Soffit Cutter : These Hole Saw Cutter Tools are pre-fitted with an Arbor Drill piece, hence giving it the name of "Welded Shank". The second part of their name "Soffit Cutter" owes to the fact that they are most suited for hole cutting within Soffit boards. Other materials include Plywood, PVC and most metals.
Diamond-Edged Hole Saw: DE Hole Saws do not have teething. These are purpose tools for dealing with ceramic based materials, commonly utilised for hole cutting ceramic tiles. The diamond material makes it hard with strong durability, tough wear resistance and high heat resistance.

How to Use a Electroplate Diamond Hole Saw
Mark the Centre
Use a pencil or punch to mark the centre of the hole you want to cut. This will guide your pilot bit and keep your saw from drifting when you begin.
Secure the Workpiece
Clamp your material in place if it’s movable. For example, if you’re cutting into timber, tile, or pipework on a bench, keep it stable to prevent spinning or slipping.
Drill the Pilot Hole (optional for harder surfaces)
For extra accuracy, especially in metal or tile, pre-drill a pilot hole using a standard drill bit the same size as the pilot in your arbor. This helps prevent wobble when starting the cut.
Align and Start Slowly
Line the pilot bit up with your mark. Start your drill at a low speed, let the pilot bit take the lead and ease the teeth of the hole saw into the surface gradually. Don't force it, the idea is that you’re guiding, not punching through.
Apply Steady Pressure
As the saw bites into the material, apply consistent, gentle pressure. Let the tool do the work because pressing too hard can cause overheating or a jammed drill.
Pull Back Regularly to Clear Dust and Cool the Blade
Every few seconds, withdraw the hole saw slightly while it’s still spinning. This helps clear debris and cool the blade, which is especially important when cutting metal.
Finish Cleanly
If you’re cutting timber and worried about splintering on the reverse side, stop before breaking through and complete the cut from the opposite side — if it’s safe and practical to do so.
Remove the Plug
Once your hole is cut, switch off the drill and remove the plug of waste material from inside the saw. If your arbor has an ejector spring, this should pop out easily. Otherwise, a screwdriver may help to lever it loose.
Continuous rim or slotted designs
Customizable pilot diameters, with or without diamond coating
Fully customizable sizes, drilling depths, rim types, shank diameters and lengths, pilot sizes, diamond depths, grit sizes, and keyhole configurations
Precision tolerances available for specialized tasks
Maintenance
Take Your Time
Slow and steady drilling avoids burning out your saw or marring your material.
01
Clear Debris As You Go
It helps with cooling and keeps your cuts neat.
02
Clean After Use
Wipe blades down and remove leftover material to prevent rust.
03
Store Dry
A sealed case keeps moisture out and parts organised.
04
Use Lubricant When Needed
Especially when working with metals — it reduces heat and wear.
