Tackle soft and hard wood with the 1-1/4 in. Solid Center Auger with Cutting Spur, designed with a solid center for extra rigidity while drilling. This bit is full-length and heat-treated to prevent bending during heavy-duty use. The coarse screw point enables fast drilling, while the single cutting spur scribes the circumference of the hole for an overall smooth finish.
- 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
