Counterbores are available in High Speed Steel and Carbide tipped, with three and four flutes, and set screw for the pilot. Counterbores are used where a flat for a bolt/nut/washer must be used when assembling the part.  

Counterbore pilots will fit most standard Counterbores, are made from quality tool steel, heat-treated, and ground to ensure concentricity.

Our HSS and Carbide tipped Counterbores are the short series with a 2 3/8” OAL and a 1/4 “ shank.  

The radius on our Carbide tipped Counterbores is 1/64” and the non cutting area of the cutter is 1/32” larger than the pilot hole.

Counterbores and pilots are manufactured in the USA.
