Harvey Tool 76450 Square End Mill 0.05 in 4 Flute Carbide

Product Description

The HARVEY TOOL 76450 is a solid carbide square end mill designed for precision milling operations requiring tight tolerances and a sharp corner geometry. With a 0.05-inch cutting diameter, a 0.15-inch length of cut, and four flutes arranged in a right-hand spiral at a 30-degree helix angle, this end mill is built for fine detail work in ferrous and non-ferrous materials. The extended reach configuration and 0.5-inch reach length make it suited for accessing recessed features and pockets where standard-reach tooling cannot reach. It is installed and operated by machinists and tooling professionals in CNC milling environments.

This end mill is suited for use in vertical machining centers and CNC mills where small-diameter, high-precision cutting is required. The bright uncoated finish makes it a practical choice for applications in aluminum, brass, copper, and other non-ferrous materials, as well as some plastics. The centercutting design allows plunge entry directly into the workpiece. With a 1/8-inch shank diameter and 1.5-inch overall length, it fits standard collet systems used in production and prototype machining environments.

Key Features

• 0.05-inch cutting diameter for fine detail and micro-feature milling
• Four flutes with right-hand cutting and right-hand flute direction for efficient chip evacuation
• 30-degree helix angle balances cutting forces and surface finish
• Extended reach design with 0.5-inch reach length for deep pocket access
• Centercutting geometry allows direct plunge entry
• Bright uncoated solid carbide construction for dimensional stability and wear resistance

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC milling machines and machining centers that accept a 1/8-inch shank collet. Compatible with applications requiring a length-of-cut range of 0.1 to 0.2 inches.

Installation Notes

This end mill is installed by qualified machinists using a collet or end mill holder rated for the 1/8-inch shank diameter. Ensure the collet is properly torqued and the shank is fully seated before operation. Verify spindle speed and feed rate parameters match the material being cut before engaging the tool. Inspect the cutting edges for chipping or wear before each use, as small-diameter carbide tools are susceptible to breakage if run out-of-spec.
