Square End Mill for Finishing Cuts

This square end mill is a general-purpose cutting tool made from cobalt steel for machining operations that require a clean, square-cornered finish. It is suited for machinists and fabricators working on manual or CNC milling machines who need a reliable tool for profiling, slotting and pocketing in a range of materials.

TiCN Coating Reduces Heat and Wear

The titanium carbonitride finish provides higher hardness and heat resistance than uncoated cobalt, allowing the tool to run at elevated temperatures without rapid degradation. A 30-degree helix angle promotes smooth chip evacuation, which helps maintain lower cutting forces and consistent performance during finishing passes.

Two-Flute Geometry with Single-End Design

The two-flute configuration offers a balance of chip clearance and core strength, making it effective for both peripheral and plunge cuts. A single-end construction with a 3/8-inch shank fits standard tool holders, while the 9/16-inch length of cut and 2-1/2-inch overall length provide reach for typical finishing applications.

Questions about this item

How do I install the 3/8 shank into my tool holder, and what step is often missed?

Insert the 3/8 shank fully into a matching collet or end-mill holder and tighten securely; the step often missed is verifying that the 2-flute, 30-degree helix tool runs true before starting the cut.

What maintenance or replacement will this cobalt end mill need later?

The TiCN coating and cobalt substrate wear gradually; when the 2-flute cutting edges dull or chip, the tool must be resharpened or replaced to maintain finish quality.

What limit appears first during sustained cutting with this 5/16 diameter end mill?

Heat buildup at the 9/16 length of cut typically becomes the limiting factor, causing coating degradation and reduced tool life before other issues arise.
