Cleveland C40038 Roughing End Mill

The Cleveland C40038 is a 3-flute roughing end mill built from powdered metal HSS-E with a TiCN coating. It features a 0.75 in milling diameter and a Weldon flat shank for secure tool holding. Designed for high metal removal rates, it suits general-purpose roughing operations in a variety of materials.

For machinists running heavy roughing passes

This tool suits operators who need aggressive stock removal on manual or CNC milling machines. The powdered metal substrate and TiCN coating handle the heat and wear of deep cuts. It is not suited for finishing passes requiring a fine surface finish or for high-speed machining strategies demanding specialised carbide geometries.

0.75 in diameter with .12 in corner radius

The 0.75 in cutting diameter provides substantial engagement for rapid material removal in slots and profiles. The .12 in corner radius adds strength to the cutting edges during heavy feeds. Overall length reaches 5 1/4 in with a 3 in length of cut, offering reach for deep pockets while the Weldon flat ensures rigid clamping.

Questions about this item

What shank size must my milling machine accept to hold this 0.75 in diameter cutter?

The tool has a Weldon flat shank; your holder must match the standard flat size for a 0.75 in diameter end mill.

Can this roughing end mill be used in a conventional knee mill without CNC rigidity?

The PM+ HSS-E substrate and TiCN coating tolerate moderate vibration, making it suitable for manual machines if feeds are kept conservative.

How do I confirm the 0.12 in corner radius is cutting correctly after installation?

Measure the first workpiece corner with a radius gauge; a clean 0.12 in fillet without chatter marks shows the tool is engaged properly.
