What You Need To Complete The Job

A 25mm bit wants a drill with a bit of torque. When you need to reach deeper, 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 25mm spade bit used for?

A 25mm spade bit drills the standard size hole for running cable, conduit and pipe through timber framing, studs and joists. It is the largest everyday drilling size in the D501 range and a staple for electricians and plumbers chasing runs through walls.

Why does the heavy duty shank matter at 25mm?

At 25mm the bit cuts a big hole and takes more torque to drive. The heavy duty shank holds it firmly in the chuck without slipping, and it is the shank that the D502 extension is built to suit for deeper work.

Can a cordless drill drive a 25mm bit?

Yes, with a decent 18V cordless drill. The D501 is designed to increase efficiency and battery life, so it runs well on cordless. Feed the bit steadily and let the chip breaker clear the waste, and the drill does not have to work as hard.

How do I drill a straight hole through a stud?

Keep the drill square to the timber and feed steadily, and the bit will follow its own line. For a long run through multiple studs, use a level or a straight edge to keep the holes in line, and an extension shank saves moving the drill on each hole.
