  • Black-oxide finish reduces friction and protects against corrosion

60-degree 3-flute countersink for metalwork

The Cleveland C46170 is a high-speed steel countersink designed for creating 60-degree chamfers in metal. Its three-flute geometry helps produce a smooth finish and reduces chatter during operation. The black oxide coating adds wear resistance for extended tool life. This accessory suits machinists and fabricators preparing holes for fasteners or deburring edges.

Limited to 60-degree chamfering

The fixed 60-degree angle cannot produce the 90-degree countersinks common for many flat-head screws. Users needing different angles must acquire separate tools. The high-speed steel construction suits general-purpose steel and non-ferrous metals but is not optimised for hardened alloys or high-volume production. Shank compatibility depends on the specific holder or chuck used.

Questions about this item

Should I pick the 60-degree or the 90-degree version for my job?

Choose the 60-degree version when the specification calls for a 60-degree chamfer; choose the 90-degree version when a 90-degree chamfer is required.

What does the 60-degree angle mean once the cutter is in the machine?

The 60-degree angle produces a 60-degree included chamfer on the workpiece, matching the geometric requirement for fasteners or fits specified at that angle.
