Cleveland C31296 Roughing End Mill

The Cleveland C31296 is a 4-flute cobalt 8% roughing end mill built for aggressive material removal. Its coarse square profile and TiCN coating extend tool life in heavy milling passes. The Weldon flat shank provides secure clamping in standard holders. It suits CNC operators and machinists who need reliable stock removal.

Suited for high-volume roughing.

This cutter serves shops that prioritise rapid metal removal over surface finish. The coarse tooth geometry excels in deep slots and wide profiles where chip evacuation matters. It is not intended for light finishing cuts, tight-tolerance contours, or non-ferrous materials that demand sharp, polished flutes. Buyers who need a fine surface finish should select a different tool.

0.375 in diameter with 1.5 in length of cut

The milling diameter is .375 in and the length of cut is 1.5 in, giving a 4:1 reach ratio for deep pocket work. Overall length measures 3 1/4 in with a matching 3/8 in shank diameter. These dimensions decide whether the tool clears the workpiece and fits the machine envelope. Verify both values against your setup before ordering.

Questions about this item

How much heat does the .375 in cobalt 8% roughing end mill generate during continuous cutting?

Heat output depends on workpiece material, cutting speed and feed rate; the 1.5 in length of cut and four-flute design help evacuate chips to reduce localised temperature.

What tool holder is required for the 3/8 in Weldon flat shank?

A standard Weldon-compatible end-mill holder with a 3/8 in bore and set-screw locking is needed to secure the flat on the shank.

Will the TiCN coating on this 31296 end mill wear faster on older manual knee mills?

TiCN coating resists abrasive wear on any rigid machine; on older manual mills maintain proper feeds and speeds to avoid chatter that can accelerate coating loss.
