- 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
- Full-length heat treated bit guards against bending in heavy duty applications and strengthens the twist where the greatest strain occurs
- Screw+spur+cutter point shape, CW spiral angle
