Sutton D501 28mm Spade Bit

The Sutton D501 is a 28mm spade bit built for fast, clean holes in timber and light building materials. Sutton states the range drills up to 5 times faster than standard spade bits, with a power chip breaker and a heavy duty shank that clear the waste quickly and keep the bit running true. The 28mm size is a larger hole, used for pipe and heavier cable runs through framing where a smaller diameter will not fit.

What You Need To Complete The Job

A 28mm bit wants a drill with strong torque. For deeper work, add a D502 300mm extension, and for a full range the D501 3 piece set is the match. For masonry, use an SDS masonry drill instead. More cutting gear is under Carpentry Tools.

Frequently Asked Questions

What is a 28mm spade bit used for?

A 28mm spade bit drills the larger holes needed for pipe runs, heavy cable and conduit through timber framing. It is a plumbers and electricians size, used when the run is too big for the everyday 20 or 25mm holes.

Do I need a heavy drill for 28mm?

At 28mm the bit cuts a large hole, so a drill with good low speed torque makes the job easier. A corded drill or a strong 18V cordless will manage it in framing timber. Feed steadily and let the chip breaker clear the waste.

Can I use this bit on hardwood?

Yes, though hardwood asks more of any bit. The power chip breaker and heavy duty shank keep the D501 cutting cleanly in dense timber, but feed a little slower and keep the edge sharp for the best result.

How do I stop the hole tearing out on the far side?

Ease the pressure as the point breaks through, and back the work with a scrap piece where you can. A sharp bit and a steady feed give a clean hole with minimal break out on exit, which is what the D501 is designed to do.
