Accupro 95169740 Corner Radius End Mill 1/2 in 5 Flute Carbide

Product Description

The ACCUPRO 95169740 is a solid carbide corner radius end mill designed for high-performance milling in demanding metal-cutting applications. Built on the HS series platform, it features a 0.5 inch mill diameter, a 1 inch length of cut, and a 0.0300 inch corner radius that reduces stress concentrations at the cutting edge and extends tool life in interrupted or finishing passes. The AlCrTiN coating provides excellent heat and oxidation resistance at elevated cutting temperatures, making this end mill well suited for hard steels, stainless steels, and high-temperature alloys. Machinists and toolroom technicians working in CNC milling environments are the primary users of this tooling.

This end mill fits standard CNC machining centers and manual mills using a straight-cylindrical 0.5 inch shank with an ER or side-lock collet system. The 5-flute, right-hand cutting, right-hand spiral geometry with variable index and chipbreaker features improves chip evacuation and reduces chatter in slotting, profiling, and finishing operations. The 3 inch overall length provides sufficient reach for most standard workpiece setups without sacrificing rigidity. It is appropriate for both roughing-to-finish and semi-finish passes in ferrous and exotic alloy materials in production and job-shop environments.

Key Features

• AlCrTiN coating for high heat and oxidation resistance in hard and abrasive materials
• 5-flute, right-hand spiral geometry with variable index for reduced chatter and improved surface finish
• Chipbreaker geometry aids chip management in deep slotting and high-feed passes
• 0.0300 inch corner radius reduces tool stress and improves corner strength at the cutting edge
• Centercutting design allows plunge entry without a pre-drilled starting hole
• Micrograin solid carbide substrate for high rigidity and wear resistance

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 0.5 inch straight-cylindrical shank.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the machine in a locked-out, de-energized state per applicable shop safety and OSHA lockout-tagout procedures. Seat the shank fully in a clean, properly sized collet or tool holder and torque the retention mechanism to the holder manufacturer's specification. Inspect the cutting edges and corner radius for chips or coating damage before use. Confirm runout with a dial indicator after tool setup to ensure accurate cutting and extended tool life.
