Cleveland C41526 Square End Mill 5/8 in 4 Flute Hss Tin

Product Description

The CLEVELAND C41526 is a 4-flute square end mill designed for precision milling in ferrous and non-ferrous materials. Manufactured from high speed steel with a titanium nitride (TiN) finish, this tool offers improved wear resistance and longer tool life compared to uncoated HSS. The mill features a 5/8 inch cutting diameter, a 1-5/8 inch length of cut, and a 3-3/4 inch overall length. The centercutting geometry allows for direct plunge entry into the workpiece, making it a versatile choice for slotting, side milling, and plunge operations. Right-hand cut and right-hand flute orientation are standard. This tool is installed and operated by machinists, tool-and-die makers, and CNC operators.

The C41526 is suited for milling cast iron, non-ferrous metals, and steel in both manual and CNC machining environments. The 30-degree helix angle promotes efficient chip evacuation and reduced cutting forces during extended passes. The HG-4C series is configured for regular-length applications where rigidity and surface finish quality are priorities. The straight cylindrical shank with Weldon flat accommodates standard end mill holders and set-screw style toolholders commonly found in vertical mills and machining centers.

Key Features

• 4-flute spiral design for improved surface finish and feed rate capability
• TiN coating increases surface hardness and reduces friction at the cutting edge
• Centercutting geometry supports direct plunge milling without pre-drilling
• 30-degree helix angle promotes chip flow and reduces heat buildup
• Right-hand cut and right-hand flute for standard milling setups
• Weldon flat on straight shank for secure toolholder engagement

Compatibility

Compatible with milling applications in cast iron, non-ferrous metals, and steel. Fits standard end mill holders and Weldon-style toolholders accepting a 5/8 inch straight shank. Designed for use in the CLEVELAND HG-4C series.

Installation Notes

Installation should be performed by qualified machinists following shop safety procedures. Ensure the machine spindle is fully powered down and locked out before inserting or removing tooling. Seat the Weldon flat against the set screw in the toolholder and torque per the toolholder specification. Verify runout at the cutting diameter before beginning the first pass.
