Accupro 95169938 Corner Radius End Mill 3/4 in 5 Flute

Product Description

The ACCUPRO 95169938 is a solid carbide corner radius end mill designed for high-performance milling in demanding machining environments. It measures 3/4 inch in diameter with a 2-1/4 inch length of cut and a 0.0600 inch corner radius, making it well suited for finishing and semi-finishing operations where a controlled edge radius is required. The five-flute geometry with a 38-degree helix angle promotes efficient chip evacuation and smooth surface finishes. An AlCrTiN coating provides thermal resistance and extended tool life in high-speed, high-temperature cutting conditions. This end mill is centercutting and single-end, intended for use by machinists and toolroom professionals on CNC milling machines and machining centers.

This end mill is used in ferrous and hardened steel applications where corner strength and wear resistance are critical. The Series HS designation targets high-speed machining strategies. The variable index geometry helps reduce chatter and harmonic vibration during deep-pocket and slotting operations. It is suitable for mold and die work, aerospace components, and general precision machining. The straight-cylindrical shank fits standard ER and side-lock toolholders with a 3/4 inch bore.

Key Features

• 0.0600 inch corner radius reduces stress concentration and improves edge durability
• AlCrTiN coating provides high-temperature wear resistance for dry and high-speed cutting
• Five-flute design with 38-degree helix angle for improved chip flow and surface finish
• Variable index flute spacing reduces chatter and vibration in aggressive cuts
• Centercutting geometry allows plunge entry and ramping operations
• Micrograin solid carbide substrate for rigidity and edge retention

Compatibility

Designed as an OEM-style solid carbide corner radius end mill for use in standard 3/4 inch straight-cylindrical toolholders on CNC machining centers and milling machines.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank fully within a clean, properly torqued toolholder to the holder manufacturer's specifications before use. Verify runout with a dial indicator prior to cutting. Always power down the spindle and lock out the machine before changing tooling.
