Harvey Tool 34709-C3 Square End Mill 9/64 in 3 Flute Carbide

Product Description

The HARVEY TOOL 34709-C3 is a solid carbide square end mill designed for precision milling in demanding metalworking and machining applications. With a 9/64 inch (0.1406 inch) cutting diameter and a 7/32 inch (0.22 inch) length of cut, this end mill is built for tight-tolerance work in small-feature milling. The 3-flute geometry balances chip evacuation with surface finish quality, and the 30-degree helix angle promotes smooth cutting action. An AlTiN coating provides thermal resistance and extended tool life in hard and abrasive materials. This tool is installed by machinists and CNC operators in production and job shop environments.

This end mill is suited for milling ferrous and non-ferrous metals, including hardened steels and alloys, where small-diameter precision cutting is required. The extended reach design, with a 1-1/8 inch reach length, allows access to deeper features or pocketed areas without compromising rigidity. It is a single-end tool intended for use in CNC machining centers and manual milling machines where a 3/16 inch shank is compatible with the spindle or collet system in use.

Key Features

• 9/64 inch (0.1406 inch) cutting diameter for small-feature and fine-detail milling
• 3-flute design balances chip clearance and finish quality
• AlTiN coating for thermal resistance and improved tool life in hard materials
• 30-degree helix angle for smooth, efficient cutting action
• Extended reach at 1-1/8 inch reach length for deeper feature access
• Centercutting construction allows plunge entry directly into material

Compatibility

Compatible with CNC machining centers and manual milling machines equipped with a 3/16 inch collet or tool holder. Designed as a direct-fit solid carbide square end mill for applications requiring a 9/64 inch diameter cutting tool with a 3/16 inch shank.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Always power down and lock out the spindle before changing tooling. Secure the shank fully within the collet or tool holder to the manufacturer-specified engagement depth to prevent pullout during cutting. Inspect the collet and holder for wear or runout before mounting, as excessive runout will reduce tool life and surface finish quality at this diameter.
