Cleveland C75099 11 mm Square End Mill

The Cleveland C75099 is a four-flute high-speed steel square end mill with a centre-cutting design. It features an 11 mm milling diameter and a 9.52 mm shank diameter with a Weldon flat for secure clamping. The tool suits general-purpose milling in ferrous and non-ferrous materials where carbide is not required.

Practical limits of high-speed steel tooling

High-speed steel offers toughness and lower cost but wears faster than carbide at high cutting speeds. The 25.4 mm length of cut and 68.26 mm overall length restrict reach in deep cavities. Uncoated finish limits performance in abrasive alloys or high-temperature applications without coolant.

Installation and common issues

The Weldon flat shank locks into a matching holder with a set screw for quick changes. Ensure the holder bore matches the 9.52 mm shank exactly to prevent runout. Common problems include chatter from excessive overhang and premature flank wear if feed rates exceed material recommendations.

Questions about this item

Should I choose the 11 mm diameter or the 9.52 mm shank size for my milling setup?

The 11 mm figure is the cutting diameter; the 9.52 mm figure is the shank diameter. Both are fixed on this tool. Select based on the cutter diameter your operation requires and the collet or holder that matches a 9.52 mm shank.

What does the 25.4 mm length of cut mean when the end mill is in the spindle?

It is the maximum axial depth the 4-flute high-speed steel cutter can engage in a single pass. Plan roughing and finishing passes so the depth of cut does not exceed 25.4 mm.

How does the Weldon flat on the 9.52 mm shank affect tool holding?

The Weldon flat provides a positive drive surface for a set-screw holder, preventing the 11 mm cutter from slipping under heavy side loads during milling.
