Cleveland C46177 Countersink 100 Degree

This Cleveland C46177 countersink creates a 100-degree chamfer in materials up to 3/4 inch diameter. It is built from high-speed steel with a black oxide finish for wear resistance. The tool suits machinists and maintenance technicians preparing fastener seats in metal stock.

Installing and common issues

Secure the shank firmly in a drill press or powered hand drill before engaging the workpiece. Use cutting fluid and moderate speed to prevent chatter and overheating. Dull flutes or excessive feed pressure often produce rough, off-centre countersinks that weaken the joint.

Who this suits and who should look elsewhere

This single 3/4 inch cutter suits shops that need one precise 100-degree angle for recurring fastener work. Buyers who want more diameters or a complete countersink set should look elsewhere. High-volume production lines needing carbide tooling will also need a different solution.

Questions about this item

How can I verify the countersink is cutting cleanly after setup?

Check that the 100-degree angle produces a flush fit for flat-head screws without chatter or burrs on the workpiece.

What comes in the box and what must I supply separately?

The box contains the C46177 high-speed steel countersink with black oxide finish; you will need a compatible drill or driver and the appropriate flat-head fasteners.

When should I choose the 100-degree version over other angles?

Select the 100-degree countersink when your drawings or fastener specifications call for a 100-degree included angle to match flat-head screw heads.
