Sutton D501 38mm Spade Bit

The Sutton D501 is a 38mm spade bit, the largest of the single sizes in this range, 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 38mm size is a big bore, used for pipe, duct and heavy penetrations through framing where a large clear hole is needed.

What You Need To Complete The Job

A 38mm bit wants a drill with strong torque and a steady feed. For deeper work, add a D502 300mm extension, and for a full range the D501 6 piece wallet 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 38mm spade bit used for?

A 38mm spade bit drills the largest single holes in the D501 range, used for pipe, duct and heavy cable penetrations through timber framing. It is a size for the big runs where a smaller spade bit cannot fit the pipe or duct.

Can a cordless drill drive a 38mm bit?

A strong 18V cordless drill can, though it is near the top of what a hand held drill comfortably drives. The power chip breaker keeps the cut moving, but a corded drill or a low-speed drill gives the steady torque a 38mm bore wants.

How do I get a clean hole through thick timber at 38mm?

Back the bit out part way to clear the waste, feed steadily, and ease off as the point breaks through. On very deep timber, use the 300mm extension and clear the hole in stages rather than forcing one long cut.

Is the 38mm bit good for soil and waste pipe?

For the smaller soil and vent pipe entries through timber, a 38mm hole gives useful clearance. Check the outside diameter of the pipe you are running and choose the bit that clears it, which is often the 38mm for the compact waste pipes.
