Cleveland C46171 3-Flute Countersink 60 Degree Angle

Cleveland C46171 3-Flute Countersink

The Cleveland C46171 is a three-flute countersink manufactured from high-speed steel for use in power and pneumatic tools. It serves machinists and technicians who require clean, precise countersunk holes in metal and other machinable materials. The tool features a 60-degree cutting angle designed for specific fastener profiles and chamfering tasks. Its high-speed steel construction provides the hardness and wear resistance needed for repetitive cutting operations.

60-degree angle capacity and headroom

The 60-degree angle suits applications such as deburring, chamfering and preparing holes for matching screw heads, delivering consistent results within its intended range. Hardened steels or abrasive composites will dull the cutting edges more quickly, limiting tool life in those materials. The single 60-degree geometry cannot produce the 100-degree countersinks required by certain fastener standards. Users needing different angles or larger diameters must select alternative tooling.
