Accupro 95168353 Corner Radius End Mill 1/4 in 5 Flute

Product Description

The ACCUPRO 95168353 is a single-end corner radius end mill designed for precision milling operations in ferrous and non-ferrous materials. It is manufactured from micrograin solid carbide and carries an AlTiN (aluminum titanium nitride) coating for elevated heat resistance and extended tool life at higher cutting speeds. The mill measures 0.2500 inches in diameter with a 0.0300 inch corner radius, a 3/8 inch length of cut, and a 2 inch overall length. The 5-flute, right-hand spiral geometry with a 45-degree helix promotes smooth chip evacuation and reduces chatter during finish passes. This is a centercutting tool, allowing plunge entry directly into the workpiece.

This end mill is suited for finish and semi-finish milling in machining centers and CNC mills where a radiused corner profile is required to reduce stress concentrations in pocketed or stepped features. The stub-length configuration provides added rigidity in tight setups. The 1/4 inch shank diameter fits standard collet chucks and end mill holders commonly found in both horizontal and vertical machining centers. It is intended for use by machinists and tool-and-die professionals working in job shops, production environments, and precision fabrication settings.

Key Features

• Micrograin solid carbide construction for dimensional stability and wear resistance
• AlTiN coating supports high-speed dry or near-dry cutting conditions
• 5-flute right-hand spiral geometry at 45-degree helix angle reduces chatter and improves surface finish
• 0.0300 inch corner radius reduces edge chipping and stress risers in milled pockets
• Centercutting design allows direct plunge milling without a pre-drilled entry point
• Stub-length body increases rigidity in shallow-reach applications

Compatibility

Designed as an OEM-style cutting tool for use in standard 1/4 inch collet chucks and end mill holders on CNC vertical or horizontal machining centers requiring a corner radius end mill profile.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully powered down and locked out per facility lockout/tagout procedures. Ensure the shank is fully seated and the collet or holder is torqued to the tool holder manufacturer's specification. Inspect the cutting edges and coating for chips or wear before each use. Do not exceed the recommended speeds and feeds for the workpiece material and coating type.
