Solid center design provides extra rigidity while boring
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, producing a faster, cleaner cut
Single-spur cutting edge scribes the circumference of the hole for a smoother finish
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
Full-length heat treated bit guards against bending in heavy-duty applications and strengthens the twist where the greatest strain occurs.
Stocked in a large range of sizes and diameters
Flat Bits
Blue-Groove point and cutting edge for faster chip removal - 4x faster than standard spade bits
Double cutting spurs scribe the outside of the hole reducing breakout
10% larger shank for added durability
Grooved hex shank prevents slipping in drill chuck or bit extension
