Cleveland C41262 Square End Mill 11/16 in 4 Flute Hss

Product Description

The CLEVELAND C41262 is a 4-flute square end mill designed for material removal and profiling operations in ferrous and non-ferrous metals. Manufactured from high speed steel, it delivers reliable cutting performance in cast iron, non-ferrous metals, and steel. The tool features an 11/16-inch cutting diameter, a 1-5/8-inch length of cut, and a 3-3/4-inch overall length. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Centercutting geometry allows plunge entry as well as conventional peripheral milling. This end mill is installed and operated by machinists and toolroom professionals in manual and CNC milling setups.

The C41262 is built for general-purpose milling in job shops, toolrooms, and production environments. Its regular-length configuration suits typical slotting, side milling, and profiling tasks on cast iron, steel, and non-ferrous workpiece materials. The 5/8-inch straight cylindrical shank with Weldon flat provides positive drive and secure tool holding in standard end mill holders and collet chucks. Right-hand cut and right-hand spiral flute geometry are compatible with conventional spindle rotation on vertical and horizontal milling machines.

Key Features

• 4-flute spiral design improves surface finish and material removal rate compared to 2-flute configurations
• 30-degree helix angle promotes chip evacuation and reduces cutting forces
• Centercutting geometry enables direct plunge milling without pre-drilling
• High speed steel construction provides toughness in interrupted cuts and varied workpiece materials
• Weldon flat on shank prevents tool pullout under heavy side loads
• Uncoated finish allows easy resharpening and reconditioning

Compatibility

Designed as an OEM-style replacement or direct-use end mill fitting standard 5/8-inch end mill holders, collet chucks, and Weldon-style tool holders used on vertical and horizontal milling machines.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and locked out per applicable machine-safety procedures. Secure the Weldon flat setscrew against the flat on the shank to the tool holder manufacturer's specification to prevent pullout. Verify runout with a dial indicator before beginning cuts. A licensed machinist or qualified toolroom technician should select appropriate feeds, speeds, and depth of cut based on workpiece material and machine rigidity.
