Cleveland 46138 60 Degree Countersink

The Cleveland 46138 is a single-flute countersink with a 60 degree angle made from high speed steel. It is designed for power and pneumatic tools used in automotive and general workshop tasks. The tool creates clean chamfers for screw heads or deburring drilled holes. Its construction suits repeated use in metal and plastic materials.

Suited for 60 degree chamfer work, not 90 degree

This countersink suits machinists and technicians who need a precise 60 degree angle for specific fastener profiles. It will not suit anyone requiring a 90 degree countersink for standard flat-head screws. Buyers needing a set with multiple angles or diameters should look at a dedicated countersink set instead. The single flute design limits material removal rate in very hard alloys.

Highlights

  • High-speed steel construction resists wear
  • Single-flute design clears chips efficiently
  • 60-degree angle suits standard countersinking tasks
  • Black oxide finish adds corrosion protection

Questions about this item

How do I install the Cleveland 46138 countersink in my drill press or hand drill, and what step is often missed?

Chuck the shank tightly, set low speed for the 60-degree flute, and apply steady pressure; the step many miss is using cutting fluid to prevent chatter.

When will the high-speed steel cutting edges need replacement or resharpening?

Replace or resharpen when the 60-degree flute stops cutting cleanly or shows visible wear; high-speed steel dulls faster in hardened steel than in aluminium.
