Cleveland C41843 Square End Mill 1/4 in 2 Flute Hss

Product Description

The CLEVELAND C41843 is a single-end square end mill designed for material removal, profiling, slotting, and peripheral milling operations in non-ferrous metals and similar workpiece materials. Manufactured from high speed steel (HSS) with a bright/uncoated finish, it features a 1/4 inch cutting diameter and a 37-degree helix angle that promotes efficient chip evacuation and smooth cutting action. With 2 flutes and a 5/8 inch length of cut, this end mill suits applications where controlled depth engagement and clean edge geometry are required. It is a center-cutting tool, allowing direct plunge entry into the workpiece without pre-drilling. Licensed machinists, tool and die professionals, and CNC operators are the typical end users.

The C41843 fits standard vertical and horizontal milling machines, CNC machining centers, and manual knee mills. Its 3/8 inch straight-cylindrical shank with Weldon flat is compatible with standard set-screw holders and collet chucks sized for 3/8 inch shanks. With a 2-7/16 inch overall length, it suits typical short-reach applications in production and maintenance machining environments. The HGA-2 series is optimized for non-ferrous metals including aluminum, brass, copper, and similar materials.

Key Features

• Center-cutting design allows direct plunge milling without pre-drilling
• 37-degree right-hand spiral flute helix promotes chip evacuation in non-ferrous metals
• Bright/uncoated finish suited for aluminum and other non-ferrous workpiece materials
• Straight-cylindrical shank with Weldon flat for positive retention in set-screw holders
• 2-flute geometry provides larger chip clearance for softer, gummy materials
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed for use in standard 3/8 inch end mill holders, collet chucks, or Weldon-style set-screw holders on CNC machining centers and manual milling machines. Optimized for non-ferrous metal workpiece materials per series HGA-2 specifications.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from its holder. Seat the Weldon flat against the set screw for positive axial retention and verify runout with a dial indicator before beginning the cut. Follow the machine manufacturer and tooling manufacturer guidelines for feeds, speeds, and depth-of-cut for the specific workpiece material.
