Cleveland 4-Flute HSS Corner Rounding End Mill

The Cleveland C75376 is a high-speed steel corner rounding end mill designed for machinists and maintenance technicians who need to create smooth radius edges on workpieces. Its four-flute configuration provides a fine finish on ferrous and non-ferrous materials during milling operations.

Practical limits of uncoated high-speed steel

Uncoated high-speed steel offers good toughness for interrupted cuts but wears faster than carbide when machining abrasive alloys or running at high surface speeds. Heat buildup in prolonged passes can reduce edge life, so coolant or reduced feed rates are advisable for harder materials.

Verify shank fit and clearance before ordering

Confirm that your tool holder accepts a Weldon flat shank, as this end mill uses that retention style rather than a plain cylindrical shank. Ensure the machine spindle provides enough clearance for the 3/4 inch cutting diameter and that the workholding allows full access to the corner being rounded.
