OSG Countersink: 82°, 1 Flute, 5/8 in Body Dia

An OSG 82° countersink creates a conical recess for flat-head screws in metal, plastic, or wood. The single-flute carbide design delivers fast, chatter-free cutting and a smooth finish. It is widely used in machining, aerospace, and automotive applications where precision countersinking is required.

The OSG 700-6254 is an 82° single-flute countersink with a 5/8 in body diameter, made from carbide. It is designed for fast cutting and long tool life. The 82° angle matches standard flat-head screw angles, ensuring proper seating and flush assembly in precision work.
