Accupro 95170366 Corner Radius End Mill 5/8 in 5 Flute

Product Description

The ACCUPRO 95170366 is a solid carbide corner radius end mill designed for high-performance milling in demanding machining environments. Built from micrograin solid carbide and coated with AlCrTiN for heat and wear resistance, this single-end tool features a 0.625-inch diameter, a 0.0300-inch corner radius, and five flutes with a variable index geometry. The 38-degree helix angle and right-hand spiral flutes promote efficient chip evacuation and stable cutting. Center-cutting capability allows plunge entry. This tool is intended for machinists and CNC operators working in job shops, tool rooms, and production facilities.

This end mill suits applications requiring a controlled corner radius to reduce stress concentrations and improve surface finish on profiled edges and pockets. It is well suited for finishing and semi-finishing passes in ferrous alloys, hardened steels, stainless steel, and similar high-temp alloys where AlCrTiN coating provides oxidation resistance at elevated cutting temperatures. The 2.5-inch length of cut and 5-inch overall length accommodate moderate depth applications in vertical machining centers and CNC mills.

Key Features

• 0.0300-inch corner radius reduces edge chipping and improves profile finish quality
• AlCrTiN coating provides high heat resistance and extended tool life in ferrous and hardened materials
• 5-flute variable index design reduces harmonic vibration during high-feed passes
• Micrograin solid carbide substrate delivers rigidity and resistance to deflection
• Center-cutting geometry allows direct plunge milling without pre-drilled entry
• Right-hand cut, right-hand spiral with straight-cylindrical shank for standard collet and end mill holder compatibility

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for CNC machining centers and manual mills accepting a 5/8-inch straight-cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank in a clean, properly sized collet or end mill holder to the full recommended grip depth before use. Verify spindle runout is within acceptable tolerance prior to cutting, as excessive runout accelerates wear on carbide tooling. Always power down and lock out the spindle before changing tooling in accordance with applicable shop safety procedures.
