Double end HSS square end mills have a cutting edge on both ends of the tool, doubling usable tool life and reducing cost per cutting edge. Available in 2, 3, and 4 flute configurations, including a 4 flute left-hand-cut, non-center-cutting (LHC, Non CC) option for specific machine setups.

Two Cutting Edges, One Tool: Once the first end wears down, flip the tool to use the second cutting edge — a straightforward way to reduce tooling costs on general-purpose work.

Flute Count: 2 flute tools clear chips fastest in slotting and deeper cuts. 3 and 4 flute versions offer a smoother finish and greater rigidity for profiling work.

LHC Non-CC Option: The left-hand-cut, non-center-cutting variant is built for specific machine and spindle rotation setups — confirm your machine's rotation direction before ordering this option.
