Sutton H127 22mm TCT Multi-Purpose Holesaw

The Sutton H127 is the multi-purpose holesaw range in the Sutton range, and this 22mm size carries the tungsten carbide tipped teeth that give the series its TCT name. The saw is built for machine or hand drilling in steel, stainless steel, cast iron, non-ferrous metals, plastic and wood, and it cuts to a 32mm depth. The body is made from bi-metal cobalt HSS, the construction Sutton uses for toughness and longer life, with the carbide tips doing the hard work on the cutting edge.

What You Need To Complete The Job

Mount this 22mm saw on a Sutton quick fit arbor with a BD26 pilot drill. Use a cutting lubricant on metal. When the job is concrete or brick, step up to an SDS masonry drill. More cutting gear is under Carpentry Tools.

Frequently Asked Questions

What makes the H127 different from the H125?

The H127 is the TCT multi-purpose series, so the teeth are tungsten carbide tipped rather than plain bi-metal. That gives the cutting edge extra wear resistance across a wider spread of materials, which is why Sutton markets the series for multi-purpose cutting work.

Do the carbide tips need a different cutting speed?

Carbide tipped teeth still want a moderate speed in steel, similar to a bi-metal saw, but they hold their edge longer across abrasive materials. Keep the feed steady and use a lubricant on metal, and the carbide tips will outlast a plain steel edge on a long run of holes.

Can I cut hardwood with this saw?

Yes. Hardwood is one of the materials the multi-purpose series handles well, and the carbide tips keep cutting through the denser timber without losing their bite as quickly as a plain HSS edge. Feed steadily and clear the flutes on deeper cuts.

Is the 22mm size good for electrical work?

Yes. A 22mm knockout is the standard entry for 20mm conduit and cable through steel panels, and the carbide tips make the saw a solid choice when you are cutting a run of holes in switchboard steel where edge life matters.
