Sutton H125 51mm Bi-Metal Cobalt M42 Holesaw

The Sutton H125 is a 51mm holesaw, the 2 inch size, made from bi-metal cobalt HSS for the tougher cutting edge the bigger diameter needs. It cuts to a 32mm depth and is built for machine or hand drilling in steel, stainless steel, cast iron, non-ferrous metals, plastic and wood. The listing places this size on the UA2 or QFX arbor with a BD24 or BD26 pilot.

What You Need To Complete The Job

A 51mm saw pulls harder than a small one, so fit it to a Sutton quick fit arbor with a BD26 pilot drill and run it in a drill with decent torque. Use a cutting lubricant in metal, and switch to an SDS masonry drill for concrete or brick. More trade tools are under Carpentry Tools.

Frequently Asked Questions

What is a 2 inch holesaw used for?

A 51mm holesaw is the size for pipe and cable entries that need a 2 inch round hole, common in plumbing for 40mm pipe penetrations through floors and walls, and in electrical work for large cable runs. It is also used for vents, fans and extractor fittings in timber and steel.

Do I need a heavy drill for this size?

At 51mm the saw has a lot of tooth contact, so a low-speed drill with good torque makes the job easier than a small high-speed drill. A corded drill or a heavy 18V cordless will handle it in sheet steel and timber. Let the saw cut at its own pace rather than forcing it.

How do I avoid overheating the teeth in steel?

Run at a moderate speed and keep a cutting lubricant on the cut so the bi-metal teeth stay cool. If you see the metal discolouring or smoke, ease the pressure and let the saw cut freely. Overheating is what dulls a good holesaw fastest.

Will this saw cut through both sides of a box?

You can cut through both walls of an enclosure if the 32mm depth reaches. For a deep box, drill the near side, clear the core, then start again on the far side. Backing the work where you can stops the teeth snatching on the exit.
