Sutton H125 19mm Bi-Metal Cobalt M42 Holesaw

The Sutton H125 is a 19mm holesaw made from bi-metal cobalt HSS for a tough cutting edge and a longer working life. It cuts to a depth of 32mm and is built for machine or hand drilling in steel, stainless steel, cast iron, non-ferrous metals, plastic and wood. The international thread pattern accepts standard arbor systems, so the saw suits a range of quick fit arbors rather than locking you into one brand.

What You Need To Complete The Job

A holesaw cuts on the rim, so you need a pilot drill to hold the centre and an arbor to connect the saw to your drill. Pair this 19mm saw with the Sutton H112 BD26 pilot drill and a quick fit arbor. For concrete and brick, change to an SDS masonry drill. The rest of your cutting kit is under Carpentry Tools.

Frequently Asked Questions

Do I need an arbor for this holesaw?

Yes. A holesaw without an arbor cannot be held in a drill chuck. The arbor screws into the thread on the top of the saw, carries the pilot drill in the centre, and its shank goes into your drill chuck. The international thread on this saw accepts the standard quick fit arbor systems sold on this site.

What pilot drill does it use?

This size is listed for the BD24 or BD26 pilot drill, both 6.35mm HSS pilots that fit the arbor and keep the saw running true on the centre mark. A sharp pilot is important because it holds the saw steady while the rim teeth start the cut.

Can I use this holesaw in a hand drill?

Yes. A 19mm saw is small enough to run in a standard corded or cordless drill, and Sutton lists it for machine or hand drilling. Run it at a moderate speed, keep the pilot centred, and ease off the pressure as the teeth break through the back of the material.

What materials can it cut?

The listing covers steel, stainless steel, cast iron, non-ferrous metals, plastic and wood. For stainless and harder steel, run at a slower speed and use a cutting lubricant so the bi-metal edge keeps its bite.
