Stop Countersinks

Series 420, 420CT, 420SC

Integral pilot male threaded shank countersink cutters are made from high speed tool steel, precision ground in one operation to ensure concentricity of pilot, cutting angle and shank. The countersink incorporates a taper between the threaded shank and the body of the cutter. This seats on a taper in the countersink unit to insure minimum eccentricity.

Cutters are available in 78° – 82° – 90° – 100° – 110° – 120°

Add “CO” after the number for cobalt. Add CT after the number for carbide tipped. Add SC for solid carbide. For two flute cutters add letter “S” after the part number.
