Harvey Tool 67708-C3 Corner Rounding End Mill 0.125in Radius

Product Description

The HARVEY TOOL 67708-C3 is a double-end corner rounding end mill designed for precision edge-breaking and radius milling on ferrous and non-ferrous materials. Built from solid carbide with an AlTiN coating, this tool delivers heat resistance and extended tool life in demanding cutting environments. It produces a 0.125 inch radius with a 0.3125 inch mill diameter and a 0.058 inch tip diameter. The 4-flute, right-hand flute geometry with a straight shank suits CNC machining centers and manual milling operations. Machinists and tool-and-die professionals rely on this geometry for consistent, repeatable corner profiles on production runs.

This end mill is suited for milling operations requiring a controlled edge radius on part corners in both prototype and production settings. The double-end configuration extends usable tool life before replacement. The flared corner rounding profile makes it appropriate for finishing passes on steel, stainless, aluminum, and similar materials where a precise, burr-free radius is required. Installation is performed by qualified machinists operating CNC or manual milling equipment.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-speed cutting
• AlTiN coating provides high-temperature oxidation resistance for extended tool life
• Double-end design doubles usable cutting ends before tool replacement
• 4-flute, right-hand straight flute geometry for smooth corner radius profiles
• 0.125 inch radius with 0.058 inch tip diameter for precise edge breaking
• Straight shank compatible with standard ER collet and end mill holder systems

Compatibility

Designed as a standard straight-shank corner rounding end mill compatible with CNC machining centers and manual mills equipped with collet or end mill holders accepting a 5.0 mm shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following standard tool-holding procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the collet or holder and torque to the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning a cutting operation.
