Sutton H125 63mm Bi-Metal Cobalt M42 Holesaw

The Sutton H125 is a 63mm holesaw, the 2 1/2 inch size, made from bi-metal cobalt HSS and built for the bigger penetrations in pipe, vent and duct work. It cuts to a 32mm depth and suits machine or hand drilling in steel, stainless steel, cast iron, non-ferrous metals, plastic and wood. At this size the saw moves onto the UA3 or QFX arbor class, which gives the larger rim the firmer mount it needs.

Frequently Asked Questions

What is a 63mm holesaw used for?

A 63mm holesaw suits pipe and duct penetrations that need a hole just over 2 and a half inches, including 50mm drainage pipe entries through floors and walls, exhaust vents, and cable runs. It is a size plumbers and roof plumbers reach for often.

Will a 63mm saw work in a hand held drill?

It can, in timber and thin sheet, if the drill has torque and you feed steadily. For steel plate or a run of holes, a pillar drill or a low-speed drill is the better tool. The key is a sharp pilot, a tight arbor and patience on the feed.

How do I know when to replace the saw?

When the teeth stop cutting and start rubbing, and a resharpening does not bring the edge back, the saw has done its run. A dull holesaw burns the work and takes far longer. Keeping a lubricant on metal cuts extends the life of the teeth.

Does the 32mm depth limit what I can cut?

It covers single skin roofing, wall cladding, timber framing and most panels. For thicker material, drill through, clear the core and continue from the far side. That keeps the holesaw working well beyond its single pass depth.
