Sutton H112 BD24 HSS Pilot Drill

The Sutton H112 BD24 is the pilot drill that runs in the centre of a holesaw arbor, sized at 6.35mm diameter and 82mm overall length. It is made from high speed steel and built to locate the saw on the mark and hold it there while the rim teeth cut. The 82mm length is the compact option for standard panel work, and the sharpened split point tip starts cleanly and reduces wandering on contact with the work.

Frequently Asked Questions

What is the difference between the BD24 and BD26 pilot?

Both are 6.35mm HSS pilot drills. The BD24 is the 82mm length for standard panel work, and the BD26 is the 105mm length for extra reach. They fit the same arbor class, so the choice comes down to how deep the work is.

Why does the pilot reduce wandering?

The split point tip bites into the surface on contact instead of skidding sideways, so the drill starts exactly where you put it. That holds the holesaw on the centre mark while the rim teeth start cutting, which gives a round hole rather than an oversized one.

Can I use this pilot with my existing holesaws?

If your holesaws use the international thread and a quick fit arbor with a 6.35mm pilot seat, yes. The BD24 is the pilot listed across the Sutton H125 and H127 range sold on this site, and it fits the same quick fit arbor as the BD26.

Is 82mm long enough for most holesaw work?

Yes. The 82mm length covers standard panel, sheet and timber work, where the pilot only needs to reach through the arbor and start the hole. The 105mm BD26 is the one to grab when you are working on a deeper or awkward surface.
