Cleveland C81666 End Mill

The Cleveland C81666 is a three-flute carbide square end mill built for general-purpose milling. Its TiAlN coating improves wear resistance and allows higher cutting speeds. The tool suits machinists and fabricators who need a reliable cutter for slotting, profiling and plunging in a range of materials.

Best for General Milling Tasks

This cutter suits shops that run standard milling operations on ferrous and non-ferrous metals. It is not designed for high-feed roughing strategies or deep-cavity work that demands extended reach. Buyers who need coolant-through capability or a longer flute length should look at other tooling options.

0.1875 Inch Cutting Diameter

The cutting diameter is 0.1875 in with a 0.625 in length of cut and a 3/16 in straight shank. Overall length measures 2 in and the tool has no neck relief. Match these dimensions to your holder and part geometry before ordering.

Questions about this item

What collet or holder do I need for the 3/16 in shank?

Use a 3/16 in collet or a Weldon flat holder that matches the straight shank diameter.

Can the 2 in overall length and .625 in length of cut reach the same features as my older high-speed steel end mills?

The 2 in overall length and .625 in length of cut are shorter than many HSS end mills, so you may need longer tooling for deep pockets.

How can I confirm the TiAlN coating is performing after the first cuts?

Look for gold-coloured chips and reduced built-up edge on the carbide flutes compared with uncoated tools.
