Cleveland C43302 Square End Mill 4 Flute Powdered Metal

Product Description

The CLEVELAND C43302 is a square end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 0.75 inch cutting diameter, a 1.625 inch length of cut, and a 0.75 inch shank diameter, with an overall length of 3.875 inches. The tool is manufactured from powdered metal (PM) high-speed steel, which provides improved wear resistance and toughness compared to conventional HSS. Four spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. This is a single-end, uncoated tool suited for general-purpose milling work on manual mills and CNC machining centers.

This end mill is used in metalworking shops for slotting, profiling, and peripheral milling applications. The coarse pitch flute geometry and right-hand cut with right-hand flute configuration make it a standard choice for a wide range of ferrous metals and alloys. It is a common selection for job shops, maintenance machining, and production environments where a reliable general-purpose PM end mill is needed without a specialty coating.

Key Features

• 0.75 inch cutting diameter with 1.625 inch length of cut for moderate-depth passes
• Powdered metal construction for enhanced wear resistance over conventional HSS
• 4-flute spiral design with 30-degree helix angle for efficient chip flow
• Right-hand cut, right-hand flute — standard orientation for most milling setups
• Coarse pitch geometry suited for general-purpose slotting and profiling
• Single-end, uncoated tool for versatile regrinding and reuse

Compatibility

Designed as an OEM-style replacement or standard tooling option for 0.75 inch collet or end mill holder setups on vertical and horizontal milling machines and CNC machining centers accepting a 0.75 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into a properly sized collet or end mill holder and torque retention hardware according to the holder manufacturer specifications. Confirm runout with a dial indicator before beginning a cut to avoid premature tool wear or workpiece damage.
