Accupro 95169871 Corner Radius End Mill 3/16 in 5 Flute

Product Description

The ACCUPRO 95169871 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hardened materials. Built on the HS series platform, it features a 3/16 inch diameter with a 5/16 inch length of cut and an AlCrTiN coating that extends tool life under high-heat cutting conditions. The 5-flute geometry with a 38-degree helix angle promotes efficient chip evacuation and smooth surface finishes. This is a centercutting tool, allowing plunge entry without pre-drilling. It is intended for use by machinists and tooling technicians in CNC machining centers and manual milling applications.

This end mill is suited for finish milling, profiling, and contouring operations where a blended corner radius is required to reduce stress concentrations in machined parts. The right-hand flute direction and right-hand cutting orientation make it compatible with standard spindle configurations. Its compact 3/16 inch diameter and 2 inch overall length make it well-suited for tight-tolerance work in die and mold applications, aerospace components, and general precision machining. The variable index feature helps reduce harmonic chatter during high-feed passes.

Key Features

• AlCrTiN coating provides heat and oxidation resistance for extended tool life in hard materials
• 5-flute design increases feed rate capability and improves surface finish quality
• 38-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Centercutting geometry allows direct plunge milling without a pilot hole
• Variable index flute spacing reduces chatter and vibration during aggressive cuts
• Micrograin solid carbide construction delivers rigidity and edge sharpness retention

Compatibility

Designed as an OEM-style replacement for solid carbide corner radius end mills used in standard 3/16 inch collet or end mill holder setups on CNC machining centers and conventional knee mills.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Seat the shank fully into a properly sized collet or end mill holder and torque the retention system per the machine tool manufacturer specifications. Verify runout with a dial indicator before beginning cuts to avoid premature tool wear or breakage.
