Harvey Tool 934862-C3 Square End Mill 1/16 in 3 Flute Altin

Product Description

The HARVEY TOOL 934862-C3 is a solid carbide square end mill designed for high-precision milling in demanding metalworking applications. With a 1/16 inch (0.0625 inch) mill diameter and a 3/32 inch (0.093 inch) length of cut, this tool is built for fine detail work in tight geometries. The three-flute configuration with a 30-degree helix angle balances chip evacuation and surface finish. An AlTiN coating provides thermal resistance and wear protection, extending tool life in ferrous and high-temperature alloy cutting. Installed by machinists and CNC operators in production and job shop environments.

This end mill is suited for precision slotting, profiling, and pocketing operations where a small-diameter tool with extended reach is required. The 7/16 inch reach length and overall length of 2.5 inches allow access to recessed features without sacrificing rigidity relative to its diameter. The 1/8 inch shank diameter fits standard collets and tool holders used on CNC machining centers and manual mills. Right-hand cutting and right-hand flute direction follow conventional milling setups. Centercutting capability allows plunge entry directly into the workpiece.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision milling
• AlTiN coating improves heat resistance and extends tool life in ferrous and exotic alloys
• Three flutes with 30-degree helix angle for balanced chip flow and surface finish
• Centercutting design permits direct plunge milling without a pre-drilled entry
• Extended reach of 7/16 inch (0.437 inch) for access to recessed features
• Right-hand cut and right-hand flute direction for standard CNC and manual mill setups

Compatibility

Designed as a direct-fit replacement for applications requiring a 1/8 inch shank, 1/16 inch diameter solid carbide square end mill in standard collet or end mill tool holders on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Use a calibrated torque wrench and the appropriate collet nut wrench when tightening to avoid shank damage. Verify runout with a dial indicator after installation, as excessive runout will significantly reduce tool life and part accuracy at this diameter.
