Cleveland C81081 Corner Radius End Mill .09 1.5

Cleveland C81081 Corner Radius End Mill

The Cleveland C81081 is a 2-flute carbide end mill with a .09 inch corner radius and 1.5 inch length of cut. It is designed for general-purpose milling in a variety of materials using standard inch-based tooling setups. Machinists and fabricators use it for profiling and slotting operations where a specific radius is required. The TiAlN coating supports higher cutting speeds and extends tool life in production environments.

Upgrade from worn or uncoated tooling

This cutter replaces dull high-speed steel or uncoated carbide mills that struggle with heat buildup and edge wear. The TiAlN coating allows faster feed rates and better chip evacuation in steel and alloy workpieces. The jump is worth it when cycle times need to improve or when a precise .09 radius must be held consistently across multiple parts. It also upgrades tooling for jobs requiring a 1.5 inch reach in deeper cavities.

Straight shank fits standard holders

The straight shank design fits directly into standard collets, end mill holders, and shrink-fit systems without adapters. Carbide construction makes the tool rigid but brittle, so secure clamping and minimal runout are essential to prevent chipping. Common issues include vibration from excessive stick-out and corner breakdown if feed rates are too aggressive for the material. Proper coolant or air blast helps manage chips in deep slots.
