Description
Drill & countersinks, sometimes referred to as center drills are meant to create a conical hole for "between centers" manufacturing processes (typically lathe or cylindrical-grinder work). That is, they provide a location for a (live, dead, or driven) center to locate the part about an axis. Guhring offers a wide range of metric and fractional size options as stock standard items.
Radius form for high fracture resistance properties, precise concentricity of the point in relationship with the body and a protected center hole.
