Sutton 10mm x 460mm D637 SDS Plus Masonry Drill Bit - 4 Cut - TCT

The Sutton D637 is a 4-cut SDS Plus masonry drill bit with a tungsten carbide tip (TCT), 460 mm overall length with a 400 mm flute length. This range has 5 sizes: 10, 12, 14, 16 and 20 mm. It is for reinforced concrete, brick, aerated concrete, stone and granite.

The unique TCT head has four thin external tips, designed for less friction. The combination spiral flute pairs a half-round spiral, which accelerates dust extraction away from the tip, with a square spiral that combines a compression channel with a depression chamber for controlled dust removal. The SDS Plus shank suits all SDS Plus rotary hammer drills. The sand-blasted finish is an environmentally friendly production method with zero heavy metals.

Drilling notes

• Use in an SDS Plus rotary hammer drill with the hammer action on (rotation plus percussion).
• Apply steady, moderate pressure and let the hammer do the work; extra force does not speed up the cut.
• Choose a length so the hole depth sits within the flute length. For deeper holes step up to a longer series.
• Withdraw the bit from time to time in deep holes to help clear dust, and clear the dust from the hole before fitting an anchor.
• Match the drill diameter to the hole size the anchor or fixing manufacturer specifies.
