Product identity
The Cleveland 75375 is a 4-flute high-speed steel corner rounding end mill with a Weldon flat shank. It is designed for machinists and fabricators who need to produce consistent edge radii on ferrous and non-ferrous workpieces using milling machines or CNC equipment.
Accessory impact
The uncoated bright finish suits general-purpose milling where coating buildup could affect radius accuracy. Four flutes provide smoother surface finishes and higher feed rates than two-flute alternatives, reducing the need for secondary deburring operations on rounded corners.
Installation notes
The Weldon flat locks securely into standard side-lock tool holders, preventing pull-out during heavy cuts. Ensure the holder set screw engages the flat fully; insufficient engagement or worn holder bores are the most common causes of vibration and poor radius quality.

Questions about this item
How often will the 4-flute HSS cutting edges on the Cleveland 75375 need resharpening or replacement?
Resharpening is required when the corner radius no longer meets tolerance; HSS allows multiple regrinds before the flute length is exhausted.
What limits continuous use of the 5/8 in corner rounding end mill first — tool deflection or heat buildup?
Heat buildup in the uncoated high-speed steel flutes typically limits sustained cuts before measurable deflection occurs.
How much heat and vibration does the Weldon-flat shank produce during all-day milling?
The Weldon flat holds the tool rigidly, so vibration stays low; heat rises with feed rate and lack of coolant rather than the shank itself.
