Accupro 95172684 Corner Radius End Mill 1/2 in 4 Flute Carbide

Product Description

The ACCUPRO 95172684 is a solid carbide corner radius end mill designed for high-performance milling applications in metal fabrication and machining environments. It features a 1/2 inch diameter, a 0.0150 inch corner radius, and four flutes with variable index and variable helix geometry. The AlCrTiN coating, applied via PVD process, provides thermal resistance and extended tool life in demanding cutting conditions. This is a single-end, centercutting tool, allowing plunge entry into workpiece material. It is primarily installed and operated by machinists and CNC programmers working in production or tool room settings.

This end mill is suited for profiling, slotting, and peripheral milling operations in ferrous and hardened materials. The VS Series designation indicates variable spacing and helix geometry engineered to reduce harmonic chatter during aggressive cuts. With a 1-1/4 inch length of cut and a 3 inch overall length on a straight cylindrical 1/2 inch shank, this tool fits standard ER and side-lock toolholders common to vertical machining centers and CNC milling machines.

Key Features

• 0.0150 inch corner radius reduces stress concentration at the cutting edge and extends tool life on contoured surfaces
• Variable index and variable helix flute geometry minimizes chatter during high-feed profiling operations
• AlCrTiN PVD coating provides elevated heat resistance and wear resistance in ferrous and exotic alloy cutting
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Micrograin solid carbide substrate delivers rigidity and edge retention in interrupted and continuous cuts
• Right-hand flute direction and right-hand cutting orientation for standard spindle rotation

Compatibility

Designed as a direct-fit replacement or new-application tool for standard 1/2 inch straight-cylindrical shank toolholders used in CNC vertical machining centers and manual milling machines requiring corner radius end mill geometry.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the shank fully into the toolholder to the minimum insertion depth recommended by the holder manufacturer, and torque retention screws or collet nuts per the toolholder specification. Verify runout against the TIR maximum of 0.0040 inch after mounting before beginning any cut.
