Conical and deburring countersink, 90°, unevenly graduated, solid carbide, cylindrical shank
Design: with radial grind of the stroke, with straight flute and chip chambers ground from solid material.
Application: for all materials with max. hardness 60 HRC. The highly uneven graduation of the cutting edges ensures extremely calm work during countersinking, resulting in a cleaner surface and a load on the cutting edges is reduced to a minimum.
