Corner Rounding End Mill 1 in

The Cleveland C75379 is a 4-flute high-speed steel corner rounding end mill with a 1 in radius and uncoated bright finish. It is intended for machinists and maintenance technicians who need to create consistent rounded edges on workpieces using milling machines or CNC equipment.

Check Shank and Holder Compatibility

Verify that your tool holder accepts a Weldon flat shank before ordering. Confirm the machine spindle provides sufficient rigidity for a 4-flute HSS cutter at the planned feed rates. Ensure coolant or lubrication strategy matches uncoated tooling requirements for the workpiece material.

Sustained Cutting Behaviour

Under continuous load the uncoated HSS flutes will generate heat more quickly than coated alternatives, so consistent chip evacuation is essential to avoid built-up edge. The 4-flute design distributes cutting forces evenly, helping maintain radius accuracy during longer passes. Tool life depends heavily on proper speeds, feeds, and cooling for the specific alloy being machined.

Questions about this item

What comes in the box with the Cleveland C75379 corner rounding end mill and what else do I need?

The package contains a single 1-inch 4-flute HSS corner rounding end mill with a Weldon flat; you will need a compatible tool holder or collet to mount it in your milling machine.

How do I choose between the available versions of this end mill?

The Cleveland C75379 is offered in one specification — 1-inch diameter, 4-flute high-speed steel, uncoated with a Weldon flat — so there are no alternative capacities or coatings to select from.

What does the 1-inch size mean when I put this cutter in my mill?

The 1-inch diameter produces a quarter-inch radius on the workpiece corner; the four-flute HSS design gives a smooth finish in steel and aluminium at standard milling speeds.
