Sutton D511 6mm Medium Series Auger Bit - 230 mm - 1/4 in Hex Shank

The Sutton D511 is a medium series solid core auger bit in tungsten chrome alloy (TCA) with a Power Groove hex shank, designed for fast cutting through holes in timber such as fence posts and railway sleepers. It comes in 12 sizes from 6 to 32 mm, with overall lengths of 225 to 330 mm and flute lengths of 165 to 240 mm.

The range is suitable for kiln dried timber hardwood, softwood, MDF and particle boards. It is not suitable for green sap woods. The solid centre is designed to add rigidity while drilling, the coarse screw point draws the bit into the work piece, and the single-spur cutting edge scribes the hole for a smoother finish. Applications for the range include DIY, trade, electrical, plumbing, carpentry, woodworking and roofing.

Using the auger bit

• Match the shank (1/4 in hex or 7/16 in hex, see the size table) to the chuck or driver you are using.
• Start at a low speed so the screw point can engage and draw the bit into the timber, then keep a steady pressure and let the bit feed itself.
• In deep holes, withdraw the bit from time to time to clear the chips from the flutes.
• Back the timber with a scrap piece, or ease off as the bit breaks through, to reduce break-out on the exit side.
