Sutton H125 Plumber Holesaw Set

The Sutton H125 plumber holesaw set is the five size kit built around the larger holes a plumber cuts for drainage, vent and exhaust work. It holds bi-metal cobalt M42 saws in 44, 57, 63, 92 and 111mm, so it skips the small electrical sizes and focuses on the big penetrations. Every saw cuts to a 32mm depth and suits machine or hand drilling in steels, cast iron, non-ferrous metals, plastic and wood.

Frequently Asked Questions

Why does the plumber set start at 44mm?

Because the small electrical knockout sizes are already covered by most kits, and a plumber doing drainage and vent work mostly needs the bigger penetrations. Starting at 44mm keeps the set focused on pipe and fitting holes from 40mm pipe up to vent and duct entries.

Are the big sizes hard to drive?

The 92 and 111mm saws have a large rim and want a drill with low-speed torque. In timber and sheet steel a corded drill or a heavy 18V cordless will manage, and a pillar drill is best for a run of large holes. Let the saw cut at its own pace.

Do all five saws use the same arbor?

Yes. The H125 series uses the international thread standard, so the one quick fit arbor and the one BD26 pilot drill drive every size in the box. You swap the saw body, not the mounting.

Can this set cut through metal roof and cladding?

Yes. The bi-metal cobalt HSS handles steel roofing and cladding cleanly, which is why the set suits vent and exhaust penetrations through roof metal. The 32mm depth covers single skin panels, and the knock-out slots make clearing the core quick.
