Harvey Tool 837862-C3 Square End Mill 1/16 in 3 Flute Carbide

Product Description

The HARVEY TOOL 837862-C3 is a solid carbide square end mill designed for precision milling in demanding metalworking and machining applications. With a 1/16 inch (0.0625 inch) cutting diameter and a 9/16 inch (0.5620 inch) length of cut, this tool is built for tight-tolerance work in small-feature geometries. The AlTiN coating provides thermal resistance and hardness at the cutting edge, extending tool life in ferrous and high-temperature alloy materials. Installed by machinists and CNC operators, this end mill suits production shops and toolrooms running vertical machining centers or CNC routers.

This end mill is suited for slotting, profiling, and peripheral milling operations where a small-diameter, short-reach tool is required. The 30-degree helix angle promotes chip evacuation and reduces cutting forces in shallow-to-moderate depth-of-cut applications. Its single-end, right-hand cutting configuration is standard for conventional CNC milling setups. The 1/8 inch shank diameter fits standard ER collets and end mill holders commonly found in production and prototype machining environments.

Key Features

• 1/16 inch cutting diameter for small-feature and fine-detail milling
• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for elevated thermal hardness and extended tool life in ferrous materials
• 3-flute geometry balances chip clearance with edge strength at small diameters
• 30-degree helix angle promotes chip flow and reduces cutting forces
• Right-hand cut and right-hand flute configuration for standard CNC milling spindles

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for CNC machining centers and milling machines accepting a 1/8 inch shank diameter end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet or end mill holder to the recommended gauge length before tightening. Do not exceed the tool's rated depth of cut or feed rate for the workpiece material.
