Harvey Tool 836947-C3 Square End Mill 3/64 in 4 Flute Altin

Product Description

The HARVEY TOOL 836947-C3 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. With a 3/64 inch (0.0470 inch) diameter and a 3/16 inch length of cut, this tool is built for tight-tolerance work in small-feature applications. The 4-flute geometry combined with a 30-degree helix angle promotes efficient chip evacuation and surface finish quality. An AlTiN coating provides thermal resistance and extended tool life in demanding cutting environments. Licensed machinists and CNC programmers working with small-diameter toolpaths will find this end mill suited to finishing passes and detail work.

This end mill is used in CNC machining centers and manual mills where small-diameter, high-precision cutting is required. The 1/8 inch shank diameter fits standard collets and toolholders common in production and job-shop environments. The 2-1/2 inch overall length provides clearance for many fixturing setups without sacrificing rigidity. Typical applications include slotting, profiling, and contouring in materials where AlTiN coating performance is advantageous, such as alloy steels, stainless steels, and cast iron. This is a single-end, right-hand cut tool with right-hand flute direction.

Key Features

• 3/64 inch (0.0470 inch) cutting diameter for small-feature precision work
• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for thermal protection and extended tool life in ferrous materials
• 4 flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows plunge entry
• Right-hand cut and right-hand flute direction; single-end configuration

Compatibility

Designed as a direct-fit replacement for 1/8 inch shank collets and toolholders in standard CNC machining centers and manual milling machines requiring a 3/64 inch diameter square end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool changer or collet is de-energized before changing tooling. Use the correct collet size for the 1/8 inch shank and torque to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a production run, as small-diameter end mills are sensitive to collet concentricity.
