Cleveland C81810 end mill
The Cleveland C81810 is a four-flute carbide end mill with a corner radius and TiAlN coating. It is designed for general-purpose milling in a range of materials. Machinists and fabricators select it for slotting, profiling, and finishing operations where tool rigidity and wear resistance matter. The single-end design suits standard tool holders in both CNC and manual setups.
Sustained cutting behaviour
Carbide construction and the TiAlN layer maintain hardness at elevated temperatures generated during extended cuts. Four flutes evacuate chips efficiently while distributing load across multiple edges, reducing deflection when the tool stays engaged for long passes. The corner radius strengthens the tip against chipping, helping the tool hold size and finish through a full production run without premature edge breakdown.
Deciding specification
The milling diameter is .0625 in with a corner radius of .01 in and a length of cut of .25 in. These three dimensions determine whether the tool can reach the feature, produce the required fillet, and clear the workpiece in a single pass. If the geometry calls for a larger radius, a longer reach, or a different diameter, this end mill will not suit the operation.

Questions about this item
How much heat does the 4-flute carbide CrN end mill generate during extended milling runs?
The carbide substrate with CrN coating reduces friction, so the tool runs cooler than uncoated carbide during long cuts.
What shank size must my collet or holder accept for the C81810 to fit?
The end mill has a 0.25 in straight shank, so a 1/4 in collet or holder is required.
Will the 0.0625 in diameter cutter work in my older manual mill with standard R8 tooling?
Yes, the 1/4 in straight shank fits R8 collets, and the 1 1/2 in overall length clears most manual-mill spindles.
