Cleveland C41612 Square End Mill 3/8 in 2 Flute Hss

Product Description

The CLEVELAND C41612 is a 2-flute, square-end, single-end end mill designed for precision milling of ferrous and non-ferrous metals. Manufactured from high speed steel (HSS), it features a 3/8-inch diameter cutting end with a 9/16-inch length of cut and a 30-degree right-hand spiral flute geometry. The straight cylindrical shank with Weldon flat accepts standard end mill holders and collet chucks. This tool is centercutting, allowing direct plunge entry into a workpiece. It is part of the CLEVELAND HG-2 series and is intended for use by machinists, tool and die makers, and general metalworking shops.

The C41612 is suited for slotting, profiling, and peripheral milling operations in cast iron, non-ferrous metals, and steel. With a regular-length geometry and 2-1/2-inch overall length, it fits standard vertical and horizontal milling machines, as well as CNC machining centers where shorter reach is acceptable. The uncoated HSS construction makes it a cost-effective choice for lower-speed conventional milling setups and regrindable tooling programs.

Key Features

• Centercutting design allows direct plunge milling without pre-drilling
• 30-degree right-hand helix promotes efficient chip evacuation in ferrous and non-ferrous materials
• Straight cylindrical shank with Weldon flat for secure tool holding
• Uncoated HSS construction supports regrinding and use in conventional milling applications
• Regular-length geometry for rigidity in slotting and profiling cuts
• Right-hand cut and right-hand flute for standard spindle rotation

Compatibility

Compatible with cast iron, non-ferrous metals, and steel workpiece materials. Designed for use in standard end mill holders and collet chucks accepting a 3/8-inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Secure the shank fully into the holder, engaging the Weldon flat set screw to prevent axial pullout under load. Ensure the spindle is at a complete stop and the machine is powered down before changing tooling. Verify runout with a dial indicator after mounting to confirm concentricity before cutting.
