Cleveland C94582 Countersink 100 Degrees

The Cleveland C94582 is a cobalt countersink with a 100-degree angle and 3/8 in diameter. It creates clean chamfers for flat-head fasteners in metal. The bright uncoated finish suits general workshop use. Machinists and maintenance technicians choose it for reliable deburring.

Cobalt construction fits standard drill chucks

The cobalt body resists heat and wear when cutting steel or alloys. It mounts directly in a drill press or hand drill without extra adapters. The single-piece design eliminates set-screw adjustments. This frees up tool-changer slots in automated cells.

Upgrades from high-speed steel countersinks

Cobalt holds an edge longer than standard HSS on abrasive materials. The jump is worth it when tool life outweighs the higher upfront cost. It does not suit users who only occasionally countersink soft aluminium or plastic. High-volume production lines gain the most benefit.

Questions about this item

How does the 100-degree angle affect chatter when the cutter is run continuously?

The 100-degree included angle is designed for standard flat-head fasteners and reduces chatter compared with steeper angles during extended drilling sessions.

Does the cobalt body run hot enough to require coolant during all-day use?

Cobalt steel resists heat buildup better than high-speed steel, so the tool stays cooler during prolonged operation, though cutting fluid still extends edge life.

What shank size must my drill chuck accept for this 3/8-inch countersink?

The countersink uses a standard 3/8-inch straight shank, so any 3/8-inch or larger drill chuck will hold it securely.
