TiN-coated Single Flute Countersinks from Rushmore for Tough Applications. The straight shank, single flute countersink tool is made from M42 solid carbide with 8% Cobalt. It supports enlarging the opening of a hole on a wide range of difficult-to-machine workpiece materials. Single flute Countersinks have a greater range of applications under its portfolio. Thanks to Titanium Nitride (TiN) coating, it performs well in heavy-duty countersinking, chamfering, or deburring. It is highly efficient in hole-making when holes are too small for a multi-flute countersink or when multi-flute countersinks chatter. These countersinks are designed for both machine tools & portable equipment. Rushmore offers single flute countersinks in 9 standard sizes ranging from 1/8" to 1-1/4" with included angles 60°, 82°, 90°to fit most head screws. Models are available in overall tool length from 1-1/2" up to 3" and shank diameter sizes of 1/8", 3/16", 1/4", 3/8", and 1/2".
