Accupro 95169903 Corner Radius End Mill 3/4 in 4-flute

Product Description

The ACCUPRO 95169903 is a solid carbide corner radius end mill designed for precision milling operations in demanding machining environments. Built from micrograin solid carbide and coated with AlCrTiN for heat and wear resistance, this single-end mill features a 0.0300-inch corner radius that reduces stress concentrations at the floor of a cut. With four flutes, a 38-degree helix, and a right-hand cutting direction, it is suited for high-speed finishing and semi-finishing passes in ferrous and hardened materials. Licensed machinists and CNC operators install this tool in standard 3/4-inch toolholders.

This end mill is used in vertical and horizontal CNC machining centers for profiling, slotting, and peripheral milling in tool steels, stainless, and hardened workpieces. The variable index flute spacing reduces chatter during interrupted cuts or when machining deep pockets. The AlCrTiN coating supports dry and near-dry cutting strategies, making it a practical choice for shops looking to extend tool life without flood coolant. Overall length of 3 inches and a 7/8-inch length of cut suit it to moderate-depth pocketing operations.

Key Features

• AlCrTiN coating for elevated heat resistance and extended tool life in hard materials
• Micrograin solid carbide substrate for rigidity and edge retention
• 0.0300-inch corner radius reduces stress risers and part edge chipping
• Four-flute, right-hand spiral design with variable index for chatter suppression
• Centercutting geometry allows plunge entry into the workpiece
• 38-degree helix angle promotes chip evacuation and smooth cutting action

Compatibility

Designed as a direct-fit replacement for 3/4-inch shank toolholders, collet chucks, and shrink-fit holders used in standard CNC milling applications.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in an E-stop state before changing tooling. Seat the shank to the full recommended grip length in the toolholder and verify runout with a dial indicator before beginning a cut. Follow the tool manufacturer feed-and-speed charts and machine shop safety protocols when establishing cutting parameters.
