Sutton H125 22mm Bi-Metal Cobalt M42 Holesaw

The Sutton H125 is a 22mm holesaw made from bi-metal cobalt HSS, built to cut steel, stainless steel, cast iron, non-ferrous metals, plastic and wood to a depth of 32mm. It is a trade and industrial quality saw that runs in a machine drill or a hand held drill. The thread is cut to the international standard, so the saw accepts the standard quick fit arbors used across the Sutton holesaw system.

What You Need To Complete The Job

Pair this 22mm saw with a BD26 pilot drill and a quick fit arbor so the saw runs true on the centre. When the job moves to concrete or brick, use an SDS masonry drill instead. More trade hand tools are under Carpentry Tools.

Frequently Asked Questions

What is a 22mm holesaw used for?

A 22mm holesaw is a common size for 20mm conduit and cable entries through steel panels and enclosures, where the knockout is made to the metric electrical standard. It is also used for pipe and cable entries in timber and for general sheet metal work.

What speed should I run it at?

A 22mm saw wants a moderate speed, not a screaming fast one. Too fast and the bi-metal teeth overheat and dull; too slow and the saw binds. In mild steel, run at a steady speed with light, even pressure, and back off as the teeth break through.

Is the 32mm cutting depth enough for my job?

The 32mm depth covers sheet steel, plate up to about an inch thick, and most panel and timber jobs. If you are cutting deeper material, drill through, clear the core, and continue from the other side, or use a saw with a longer body.

Can I cut stainless with this saw?

Yes, stainless is on the listed material range. It is harder on the teeth, so run at a slower speed, use a cutting lubricant, and keep the feed steady so the edge cuts rather than rubs. The cobalt in the HSS helps the teeth hold up on the harder metals.
