Cleveland Countersink 60° Cobalt

The Cleveland C94563 is a 5/8 in single-flute countersink with a 60 degree angle. It is made from cobalt steel and has a bright uncoated finish. The tool is designed for chamfering and deburring holes in metal.

Suited for metal deburring and chamfering

Machinists and fabricators who need a 60 degree countersink for general steel work will find this cobalt tool effective. It is not intended for wood or plastic applications. Buyers needing a different included angle or a coated cutter for high-volume production should look at other options.

60 degree included angle

The 60 degree angle is the critical specification that determines if this countersink matches the fastener or print requirement. Verify the required angle before ordering. The cobalt construction offers heat resistance for steel cutting.

Questions about this item

How is the 5/8 in 60° cobalt countersink installed in a drill chuck and what step is often missed?

Insert the shank fully into the chuck and tighten securely; the step often missed is verifying the tool runs true before applying pressure to the workpiece.

What maintenance or replacement will this bright uncoated cobalt countersink need later?

The cutting edges will dull with use; resharpen the 60° flutes or replace the tool when holes show chatter or oversized countersinks.

What limit appears first on this cobalt countersink during sustained high-speed drilling?

Heat buildup at the cutting edges is the first limit; cobalt resists heat well but excessive speed without coolant will accelerate edge wear.
