Cleveland C94561 Countersink
The Cleveland C94561 is a 3/8 inch cobalt countersink with a 60 degree angle and an overall length of 1-7/8 inches. It is designed for deburring and chamfering holes in metal, plastic and wood. The bright uncoated finish helps reduce friction and material buildup during use. This accessory fits standard drill chucks and quick-change holders.
Installation and common issues
The countersink installs directly into any drill chuck that accepts a 3/8 inch shank; simply tighten the jaws securely before starting the motor. Cobalt steel is brittle, so applying excessive feed pressure or running at very high RPM can cause the cutting edges to chip. Always use cutting fluid when working in steel and clear chips frequently to prevent overheating and premature wear.
Who this suits and who should look elsewhere
This tool suits machinists, maintenance technicians and DIY users who need a durable countersink for general-purpose hole preparation in ferrous and non-ferrous materials. Buyers who require a coated tool for extended life in abrasive alloys or high-volume production should look elsewhere. Users needing a larger diameter, a different included angle or a multi-piece set will need a different product.
