Extended-Length Chip-Clearing Drill Bits
Access hard-to-reach spots and drill deep holes. Parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow. The split point keeps the bit centered without a pilot hole.

Replaceable Carbide-Insert Drill Bits
Use these bits to drill a large number of holes with high precision. When the cutting edges dull, replace the carbide inserts (sold separately) instead of the entire bit. Each drill bit requires two inserts—one on the inner cutting edge and one on the outer cutting edge. Bits can be used in CNC machines with coolant-through technology; holes in the bit allow coolant to be channeled through the tool for more efficient chip evacuation.
