These single-flute high-carbon steel bits are accurately ground and have excellent chip-carrying capacity. Usually used at low speeds, they have a well-formed lead screw, a single scoring spur, and hexagonal shanks (bits 3/4" and larger require a 1/2" chuck).
These are construction bits and are intended for use on softwoods or green hardwoods only. They will work with dry hardwood, but eventually burning the scoring spur is almost inevitable. Though we offer 1/4" bits, they must be used with care as the generous flute size makes the small bits inherently weaker.
All of this sounds a bit negative, but it is just realistic. These are good bits at a very good price. They will serve you well if treated reasonably.
Overall bit length of 18".
