The Blue Groove 4X wood drill bits are 4 times faster than standard flat wood bits. The 1/4'' hex shank prevents slipping in the chuck. The specially designed blade cuts wood 4 times faster and speeds up chip ejection. The cutting edge also ensures fast chip removal. Double cutting spurs score the outer edge of the hole, reducing the risk of wood breakage. They also provide clean holes and reduce the risk of splintering. A thicker cutting edge ensures longer bit life. A 10% larger shank provides additional reinforcement.
