Cleveland C41527 Square End Mill 3/4 in 4 Flute Hss Tin

Product Description

The CLEVELAND C41527 is a square end mill designed for material removal and profiling operations on a milling machine or machining center. It features a 3/4 inch cutting diameter, a 1-5/8 inch length of cut, and a 3/4 inch straight cylindrical shank with Weldon flat. The tool is manufactured from high speed steel (HSS) and finished with a titanium nitride (TiN) coating, which improves surface hardness and extends tool life in moderate to high-speed applications. With four spiral flutes and a 30-degree helix angle, it provides efficient chip evacuation and smooth cutting action. It is centercutting, allowing plunge entry into the workpiece.

This end mill is suited for machining cast iron, non-ferrous metals, and steel in both job shop and production environments. The HG-4C series regular-length geometry works well in standard side milling, slotting, and contouring operations where a 3/4 inch tool diameter is specified. Right-hand cut and right-hand flute configuration match conventional machine spindle rotation. Machinists, tool and die makers, and CNC operators in metalworking shops are the primary users of this tool.

Key Features

• 3/4 inch cutting diameter with 1-5/8 inch length of cut for standard depth milling
• High speed steel construction with TiN coating for improved wear resistance
• Four spiral flutes at 30-degree helix angle for efficient chip removal
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Straight cylindrical shank with Weldon flat for positive tool holding
• Right-hand cut, right-hand flute — compatible with standard spindle rotation

Compatibility

Designed as a standard-geometry replacement end mill for milling applications in cast iron, non-ferrous metals, and steel. Fits any milling machine or machining center with a 3/4 inch collet, end mill holder, or Weldon-style tool holder.

Installation Notes

Installation should be performed by a qualified machinist following the tool holder manufacturer torque and runout requirements. Ensure the machine spindle is fully stopped and the machine is locked out before changing tooling. Verify shank engagement depth meets the tool holder minimum specification before operation. Select feeds and speeds appropriate for the workpiece material and HSS tooling per standard machining references.
