Cleveland C94594 Countersink/Deburring Tool Set 5 Pieces 90 Degrees Cobalt

5-Piece Cobalt Countersink Set

The Cleveland C94594 set provides five cobalt countersink and deburring tools with a 90-degree angle. It is designed for metalworkers and fabricators who need clean, chamfered holes in steel, stainless steel and other hard alloys. The bright uncoated finish preserves the cobalt substrate for high heat resistance. Each tool suits hand-held drills and drill presses in workshop and maintenance tasks.

Sustained Cutting Performance

Cobalt construction keeps cutting edges hard during extended drilling sessions, reducing the need for frequent tool changes. The 90-degree geometry produces consistent chamfers across multiple workpieces without wandering. Bright uncoated flutes evacuate chips efficiently when cutting deep or repetitive holes. The five-piece assortment lets operators switch sizes to match hole diameters without interrupting workflow.

Heat, Noise and Power Considerations

Cobalt steel tolerates the elevated temperatures generated by sustained high-speed drilling in tough metals. Uncoated surfaces avoid coating delamination that can occur under heavy feed pressure. Noise and vibration levels depend on the driving tool, workpiece rigidity and cutting parameters selected by the operator. Standard cutting fluid or lubricant is recommended to manage heat and extend tool life.
