MAKITA D-07478 Single Spur Wood Auger Bit Round Shank 16x400 mm

MAKITA D-07478 Single Spur Wood Auger Bit, Round Shank, Size 16x400 mm
The MAKITA D-07478 drill bit is a wood auger bit focused on drilling medium-to-large diameter holes at extra-deep depths. With an overall length of 400 mm, it is the ideal tool for drilling through very thick wood such as timber beams or complex structures in construction work.Self-feeding: The tip of the bit features a threaded screw point that grips and pulls the bit into the wood automatically, eliminating the need for heavy pushing effort from the user and ensuring continuous, fast drilling.Single Spur Design: The bit features a lead cutting spur that scores the wood fibers cleanly around the edge of the hole before the main cutting edge cuts the wood, resulting in clean holes and reduced splintering.Shank: This bit model utilizes an approx. 10.5 mm straight (round) shank, which is compatible with standard drill chucks.
