Sutton D501 20mm Spade Bit

The Sutton D501 is a 20mm 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. That combination also increases the efficiency and battery life of your power tool, which matters when you are running a cordless drill through a long day of framing.

What You Need To Complete The Job

A 20mm bit suits a corded or cordless drill with enough torque. When you need to reach deeper, add a D502 spade bit extension, and for a full range in one kit the D501 3 piece set is the match. For masonry work, use an SDS masonry drill instead. More cutting gear is under Carpentry Tools.

Frequently Asked Questions

What is a 20mm spade bit used for?

A 20mm spade bit drills the size of hole you need for running cable, conduit and small pipe through timber studs, joists and framing. It is a common electrical and carpentry size, big enough for most cable runs but still easy to drive in a hand held drill.

How does a power chip breaker help?

The chip breaker breaks the cut waste into smaller pieces as the bit turns, so it clears out of the hole instead of jamming the cutting edge. That lets the bit cut faster and cleaner, and it is one of the reasons Sutton rates the range at up to 5 times faster than standard spade bits.

Will this bit work in a cordless drill?

Yes. The heavy duty shank and the clean cutting design are made to run well in a cordless drill, and Sutton lists the bit as increasing efficiency and battery life. Use a drill with decent torque and feed the bit steadily through the timber.

How do I stop the wood splitting on exit?

Ease the pressure as the point breaks through the far side, 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.
