Square End Mill for Finishing

This Cleveland square end mill is a general-purpose cutting tool made from high-speed steel with a TiCN finish. It suits machinists and fabricators performing finishing operations on a range of materials. The two-flute, single-end design provides a standard geometry for milling tasks. It is not intended for roughing or heavy material removal applications.

Sustained Cutting Behaviour

The 30-degree helix angle promotes consistent chip evacuation during extended finishing passes. High-speed steel construction maintains acceptable edge retention when run at appropriate speeds for the material. The TiCN coating reduces friction and heat buildup at the cutting interface over time. Operators must manage feed rates to prevent excessive tool deflection in deeper slots.

Fractional Inch Shank Interface

The 3/8-inch shank diameter fits standard fractional-inch tool holders and collets. This shank size limits the tool to holders accepting that specific diameter. The 2-1/2-inch overall length determines the maximum reach within the holder assembly. Users requiring metric shank compatibility or longer reach must select a different tool specification.

Questions about this item

Does the 30-degree helix on this end mill run quietly and stay cool during a full day of milling?

The 30-degree helix and TiCN finish are designed to reduce cutting forces and heat buildup, helping the tool run smoothly through extended finishing passes.

What tool holder or collet do I need to fit the 3/8-inch shank on this cutter?

You will need a 3/8-inch end-mill holder, ER collet, or Weldon flat holder that accepts a 3/8-inch diameter shank for secure clamping.

Will this 5/16-inch, two-flute mill work in an older manual knee mill that only takes fractional-inch tooling?

Yes, the fractional 5/16-inch diameter, 3/8-inch shank, and 2-1/2-inch overall length match traditional manual-mill tooling standards.
