Accupro 95169967 Corner Radius End Mill 3/8 in 4 Flute

Product Description

The ACCUPRO 95169967 is a solid carbide corner radius end mill designed for high-performance milling operations in ferrous and hard materials. It features a 3/8-inch diameter, a 7/8-inch length of cut, and a 2.5-inch overall length. The four-flute, right-hand spiral design with a 38-degree helix angle promotes efficient chip evacuation and smooth surface finishes. An AlCrTiN coating provides excellent heat and oxidation resistance, extending tool life in demanding cutting conditions. The variable index geometry reduces chatter and vibration during aggressive cuts. This tool is installed and used by machinists and CNC operators in job shops, production facilities, and toolrooms.

This end mill is suited for profiling, slotting, and contouring applications where a blended corner radius is required to reduce stress concentrations in workpiece corners. The 0.020-inch corner radius makes it appropriate for finishing passes in mold and die work, aerospace components, and precision machined parts. The centercutting design allows plunge entry directly into the workpiece. The micrograin carbide substrate supports use in hardened steels, stainless steel, titanium, and other difficult-to-machine alloys where heat buildup and tool wear are primary concerns.

Key Features

• AlCrTiN coating for high heat resistance and extended tool life in hard materials
• Micrograin solid carbide substrate for rigidity and wear resistance
• 0.020-inch corner radius reduces stress risers and improves part finish quality
• 38-degree helix angle promotes efficient chip flow and reduced cutting forces
• Variable index flute spacing minimizes chatter during aggressive milling passes
• Centercutting design permits direct plunge entry without pre-drilled pilot hole

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 3/8-inch straight shank end mill in the HS series.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or end mill holder to achieve full shank engagement and secure clamping. Follow machine tool manufacturer guidelines for runout tolerance and tool projection to maintain dimensional accuracy and tool life.
