Cleveland C94593 Countersink Set 82°

This five-piece countersink set from Cleveland is designed for creating clean 82-degree chamfers in metal and other materials. The cobalt construction provides high hardness and heat resistance for extended tool life. It suits machinists, fabricators and maintenance technicians who need reliable deburring and countersinking performance.

Cobalt material for heat resistance

Cobalt steel retains hardness at elevated temperatures generated during cutting, reducing wear compared with standard high-speed steel. The bright uncoated finish avoids coating buildup that can affect hole quality. Normal use produces manageable heat and vibration when operated at appropriate speeds for the workpiece material.

Five-piece range covers common sizes

The set supplies five countersinks to handle a variety of hole diameters without needing separate purchases. Each tool is ready to use straight from the package with no additional accessories or software required. Buyers who need coated tools for abrasive materials or specialised angles not included here will need to source those separately.

Questions about this item

How do I install the 82° countersinks from the Cleveland C94593 set, and what step is often missed?

Chuck the bright uncoated cobalt shank into a drill or driver, then apply steady axial pressure while keeping the tool perpendicular to the workpiece; the step users skip is clearing chips frequently to prevent chatter.

What maintenance or replacement will the Cleveland C94593 countersinks need later?

The bright uncoated cobalt cutters will dull with use; resharpen the 82° flutes on a bench grinder or replace individual bits when cutting edges no longer produce clean chamfers.

What limit appears first when using the Cleveland C94593 set under sustained drilling?

Heat buildup in the uncoated cobalt bits is the first limit; prolonged high-speed drilling softens the cutting edges, so reduce RPM and use cutting fluid to extend tool life.
