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.

Questions about this item
How hot do the cobalt cutters get during extended deburring sessions?
Cobalt steel resists heat buildup better than standard high-speed steel, so the cutters stay cooler during prolonged 90-degree countersinking.
What shank size must my drill chuck accept to run these countersinks?
Each tool in the C94594 set uses a straight shank that fits standard drill chucks; check your chuck capacity before use.
Will the 90-degree angle match the countersink holes in my older machine screws?
The 90-degree profile is the industry standard for most flat-head machine screws, so it aligns with legacy fastener heads.
