Hexagonal shanks for sure grip in the chuck. Sharp cutting lip and a wide single spiral flute gives ample clearance for chip flow. Center screw point starts hole and helps pull bits through material.
Full length heat treated bit with wide lands keep the bit straight as it bores through the hole. The flutes are ground behind the lands to funnel chips to the inside of the bit and away from the outside diameter. Single spur cutting edge scribes the circumference of the hole; coarse screw point provides fast boring in hard and soft woods. All bits have a 4-1/2" twist length and a 7-1/2" overall length.
