Sutton H127 20mm TCT Multi-Purpose Holesaw

The Sutton H127 is the multi-purpose holesaw series in the Sutton range, and this 20mm size carries the tungsten carbide tipped teeth that give the series its TCT name. It 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 bi-metal cobalt HSS, the construction Sutton uses for toughness and longer life, with the carbide tips doing the cutting edge work.

Frequently Asked Questions

What is a 20mm holesaw used for?

A 20mm holesaw is the standard size for 20mm conduit and cable entries through steel panels and junction boxes, and it is a common electrical size. It also cuts timber and plastic panels cleanly, which makes it a useful all rounder in a trade kit.

Why pick the TCT version for a 20mm saw?

If you cut a lot of steel, the tungsten carbide tipped teeth hold their edge much longer than a plain bi-metal edge on the same size saw. For a sparkie cutting a run of holes in switchboard steel, the TCT tips make the saw last noticeably longer.

Can I use it in a cordless drill?

Yes. A 20mm saw is easy to drive in a standard 18V cordless drill. Run at a moderate speed, let the pilot start the hole, and feed steadily. It is one of the smallest and most controllable sizes in the holesaw range.

Does the saw need a separate pilot drill?

Yes. The pilot drill is sold separately and is the 6.35mm BD24 or BD26 HSS pilot listed for this size. The pilot fits the arbor and holds the saw on the centre mark while the rim teeth start the cut.
