Carbide Reverse Countersinks
181 Series
181 SERIES carbide reverse countersinks are similar in design to the 180 Series speed cutters. They excel in cutting highly abrasive materials, the “difficult to machine” materials, and in cutting any material where longer tool life is desired. 186 Series step pilots are recommended for use with carbide tipped cutters as tipped cutters have a maximum non-cutting diameter 1/32 larger than pilot hole, see sketch.
Standard in three flutes with 100 degree countersink angle. Special “D” cutter diameters readily ground from standard. Special sizes given prompt attention.
