Accupro 95172698 Corner Radius End Mill 3/4 in 4 Flute

Product Description

The ACCUPRO 95172698 is a solid carbide corner radius end mill designed for precision milling operations in metal cutting and machining environments. It features a 3/4-inch diameter with a 0.0300-inch corner radius, a 4-flute spiral geometry, and a 1-1/2-inch length of cut. The AlCrTiN PVD coating provides high-temperature resistance and extended tool life in demanding materials. This is a single-end, centercutting tool, meaning it can plunge directly into the workpiece as well as cut on the periphery. It is installed and operated by machinists and CNC tool-setup technicians working on vertical or horizontal machining centers.

This end mill is suited for finish and semi-finish milling passes in ferrous metals, hardened steels, stainless steels, and similar difficult-to-machine alloys where corner radius geometry is required to reduce stress concentration and improve surface finish. The VS series variable index and variable helix design helps suppress harmonic chatter during extended cuts. The right-hand cutting, right-hand flute direction configuration fits standard spindle toolholders with a 3/4-inch straight-cylindrical shank bore. Typical applications include die and mold work, aerospace component machining, and general precision job-shop work.

Key Features

• Solid carbide micrograin substrate for rigidity and wear resistance in hard materials
• AlCrTiN PVD coating for elevated heat resistance and extended cutting tool life
• Variable index and variable helix geometry reduces chatter in demanding cuts
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• 0.0300-inch corner radius reduces edge chipping and improves workpiece surface finish
• Single-end, 4-flute configuration balances chip evacuation with finish quality

Compatibility

Designed for use with standard 3/4-inch straight-bore toolholders including collet chucks, hydraulic chucks, and shrink-fit holders on CNC vertical or horizontal machining centers requiring a corner radius end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the spindle before seating or removing the tool from the toolholder. Ensure the shank is fully seated to the recommended gauge line depth and that the toolholder bore meets the h6 shank tolerance specification to maintain runout within the 0.0029-inch TIR maximum. Verify spindle direction is set to right-hand rotation before initiating any cut.
