Accupro 95168396 Corner Radius End Mill 1/4 in 4 Flute

Product Description

The ACCUPRO 95168396 is a solid carbide corner radius end mill designed for precision milling in ferrous and hardened materials. It features a 1/4-inch cutting diameter with a 0.0300-inch corner radius that reduces stress concentrations at the tool tip and extends tool life in demanding cuts. The 4-flute, right-hand spiral geometry promotes efficient chip evacuation while maintaining a quality surface finish. An AlTiN coating provides thermal and oxidation resistance, making this end mill well-suited for high-speed dry or near-dry machining applications. Machinists and tooling professionals in production shops and job shops install this tool in CNC machining centers and milling machines.

This end mill is built for single-end use with centercutting capability, allowing plunge entry into workpieces. The 3/8-inch length of cut and 2-1/8-inch reach length make it appropriate for accessing features at moderate depth without sacrificing rigidity. The extended reach design accommodates stepped or recessed workpiece geometries common in die, mold, and precision component machining. The 1/4-inch shank diameter fits standard ER collet chucks and end mill holders used across most CNC milling setups.

Key Features

• 0.0300-inch corner radius reduces tool stress and improves workpiece edge quality
• AlTiN coating enhances heat resistance for high-speed and dry machining
• 4-flute right-hand spiral design balances material removal rate and finish quality
• Centercutting geometry allows direct plunge milling
• Extended reach of 2-1/8 inches suits recessed or deep-feature workholding setups
• Micrograin solid carbide construction provides hardness and wear resistance

Compatibility

Designed as an OEM-style replacement-grade solid carbide corner radius end mill compatible with standard 1/4-inch ER collet chucks and end mill holders used in CNC vertical and horizontal milling machines.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Follow the tool holder manufacturer's torque specifications when tightening collet nuts or set screws. Verify runout with a dial indicator before cutting to protect both the tool and the workpiece.
