Accupro 95168429 Corner Radius End Mill 0.5 in 4 Flute

Product Description

The ACCUPRO 95168429 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hard materials. With a 0.5-inch diameter, a 0.1200-inch corner radius, and an AlTiN (aluminum titanium nitride) coating, this tool handles high-temperature cutting environments where uncoated carbide would wear prematurely. The 4-flute, right-hand spiral geometry with a variable helix provides efficient chip evacuation and reduced chatter. It is a single-end, centercutting tool, meaning it can plunge directly into material as well as cut laterally. Machinists and toolroom technicians working in job shops, production facilities, or maintenance environments select this end mill for profiling, slotting, and contouring operations.

This end mill is suited for use in CNC machining centers and manual mills where a stub-length, close-tolerance tool is required. The 0.5-inch shank diameter fits standard ER collets and end mill holders common across most vertical and horizontal machining centers. Its 5/8-inch length of cut (0.6250 inches) and 2.5-inch overall length make it well-suited for shallow-to-medium-depth passes in mold work, die work, and general part profiling. The micrograin carbide substrate supports high surface footage and extends tool life in alloy steels, stainless steels, and hardened materials.

Key Features

• 0.1200-inch corner radius reduces stress concentration and extends tool life at part corners
• AlTiN coating provides high heat resistance and oxidation protection at elevated cutting speeds
• Variable helix design reduces harmonic vibration and chatter during aggressive cuts
• Centercutting geometry allows direct plunge entry without a pre-drilled hole
• Micrograin solid carbide substrate maintains edge integrity in hard and abrasive materials
• Right-hand cut, right-hand spiral flute configuration suits standard CNC spindle rotation

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 shank diameter toolholder or collet.

Installation Notes

Install and remove end mills only with the machine spindle fully stopped and the machine locked out per your facility safety protocol. Seat the shank fully in the collet or end mill holder to the minimum recommended engagement depth before torquing the retention nut. Inspect the collet bore and tool shank for chips or contamination before seating, as debris causes runout and premature edge failure. Tool changes on CNC equipment should follow the machine builder guidelines for spindle orientation and toolholder seating.
