Cleveland 60° single-flute countersink

The Cleveland C46121 is a single-flute countersink with a 60° angle, designed for deburring and chamfering holes in metal or plastic. It fits pneumatic or power-tool chucks for workshop and maintenance tasks.

High-speed steel with black-oxide finish

High-speed steel construction resists wear during repetitive countersinking, while the black-oxide coating reduces friction and corrosion. The single-flute geometry clears chips efficiently in hand-held or fixture-mounted operations.

Replaces worn or multi-flute countersinks

This tool upgrades from dull or chipped countersinks that leave rough edges, and from multi-flute versions that clog in softer materials. The jump is worth it when a clean 60° chamfer is required for fastener seating or deburring.

Questions about this item

What angle does the 60-degree single-flute countersink actually produce?

The tool is a 60-degree single-flute countersink, so it cuts a 60-degree chamfer in the workpiece.

What shank style lets this countersink mount in my pneumatic driver?

The accessory uses a standard pneumatic shank that fits common air-powered quick-change chucks.

How do I install the countersink bit without it slipping in the chuck?

Insert the shank fully into the quick-change chuck until it locks, then tug gently to confirm engagement before running the tool.
