Sutton D502 300mm Spade Bit Extension

The Sutton D502 is a 300mm extension shank that increases the reach of Sutton spade bits 19mm and over. It lets you drive a spade bit deeper into the work, which is the tool you need when you are running holes through deep timber framing, thick walls or floor joists and the bit shank alone cannot reach. 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.

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.

Will the extension affect the straightness of the hole?

With a steady feed and the drill held square, the extension gives a straight hole through deep timber. The longer setup has a little more flex than a short bit, so feed evenly and let the bit do the cutting.

Why use an extension instead of a longer bit?

An extension is cheaper and more flexible than owning long versions of every spade bit size. One D502 shank turns the whole D501 range into deep reach bits, which is why it earns a place in the kit.

Is the extension worth carrying on site?

Yes. One extension shank turns every D501 spade bit from 19mm up into a deep reach bit, which saves carrying a set of long bits. It is a small, light tool that earns its place when you are running holes through walls and floors.
