Cleveland C38935 Keyway End Mill 2 Flute Hss Tin

Product Description

The CLEVELAND C38935 is a 2-flute keyway end mill designed for precision slotting and finishing operations in metalworking applications. Built from high speed steel with a titanium nitride (TiN) finish, this centercutting end mill offers good wear resistance and heat tolerance for general milling work. The cutting diameter is 0.25 inches with a length of cut (LOC) of 0.5 inches, a straight Weldon flat shank measuring 0.375 inches in diameter, and an overall length (OAL) of 2.4375 inches. The 30-degree helix angle supports smooth chip evacuation during finishing cuts. This tool is intended for use by machinists and toolroom professionals working in manual or CNC milling environments.

The C38935 is suited for finishing operations in ferrous materials including steel and cast iron. Its centercutting geometry allows it to plunge directly into workpieces, making it practical for keyway slotting, pocket milling, and profile work. The Weldon flat shank provides a secure, slip-resistant connection in standard set-screw tool holders. This end mill fits into general-purpose production and toolroom setups where a compact, short-LOC finishing mill is required.

Compatibility

Designed for use in standard 0.375-inch diameter collet chucks or Weldon flat end mill holders on manual knee mills and CNC machining centers. Compatible with steel and cast iron workpiece materials as noted in the CLEVELAND HG-2K series specifications.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling guidelines. Ensure the spindle is fully de-energized and locked out before inserting or removing the end mill from the tool holder. Tighten the set screw against the Weldon flat securely to prevent axial pullout under cutting loads. Always verify runout with a dial indicator after tool setup and before beginning a cut.
