Sutton D502 150mm Spade Bit Extension

The Sutton D502 is a 150mm extension shank that increases the reach of Sutton spade bits 19mm and over. It gives you the extra length to drill deeper through timber framing, walls and joists without moving the drill, while staying short enough to control in tight work. The extension connects to the heavy duty shank of the D501 spade bit range.

Frequently Asked Questions

Which spade bits work with this extension?

The listing states the D502 increases the reach of spade bits 19mm and over, which is the Sutton D501 range from 19mm up to 38mm. The smaller D501 bits under 19mm do not suit the extension shank.

What is the difference between the 150mm and 300mm extension?

The 150mm gives a moderate reach that stays easy to control in tight work, while the 300mm gives the full reach for very deep timber and thick walls. Many trades keep both, using the shorter one for everyday holes and the longer one for deep runs.

How do I fit the extension?

The extension sits between the drill chuck and the spade bit, connecting to the heavy duty shank of the D501 bit. Fit the bit into the extension and the extension into the chuck, and you have the extra reach without moving the drill.

Does a longer setup bend more in the hole?

There is a little more flex in an extended setup than a short bit, so feed evenly and keep the drill square to the work. The 150mm length keeps that flex small, which is why it is a good everyday reach for most jobs.

Can I use the extension in a drill chuck directly?

Yes. The extension goes straight into the drill chuck and the spade bit fits into the other end, so the setup works with any standard drill. Fit it firmly, keep the drill square to the work, and feed steadily for a straight hole.
