Smooth-Finish Drill Bits for Wood
Carbide-Tipped Steel
Alloy Tool Steel
Bore clean, flat bottom holes in soft wood, veneer, and laminates. The center guide point prevents the bit from wandering. Also known as Forstner bits.
Carbide-tipped steel drill bits maintain their sharp edges longer than alloy tool steel bits, and can cut through tough, abrasive material such as plywood, hard wood, and composites.
