Accupro 95169785 Corner Radius End Mill 1/4 in 4 Flute

Product Description

The ACCUPRO 95169785 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 1/4 inch diameter, a 1 inch length of cut, and a 0.090 inch corner radius, making it well suited for producing blended floor-to-wall transitions and reducing stress concentrations in machined pockets and slots. The AlCrTiN coating provides heat and wear resistance during high-speed cutting. With four flutes and a right-hand spiral flute direction, this tool is built for efficient chip evacuation and consistent surface finish. It is installed and operated by machinists and CNC programmers in production and job shop settings.

This end mill is intended for use in CNC machining centers and manual milling machines where corner radius profiling, slotting, and peripheral milling are required. The centercutting design allows plunge entry into the workpiece. The variable index flute spacing helps reduce harmonic vibration during cutting. With a 38 degree helix angle and micrograin solid carbide substrate, this tool performs well in ferrous and hardened materials. It is a single-end tool with a straight cylindrical shank, suitable for standard collet or end mill holders.

Key Features

• AlCrTiN coating for elevated heat resistance and extended tool life in hard and abrasive materials
• 0.090 inch corner radius reduces stress risers in pocketed features
• 4-flute, right-hand spiral design promotes efficient chip removal and smooth surface finish
• Variable index flute geometry reduces chatter and harmonic vibration
• Centercutting capability allows direct plunge milling without pre-drilling
• Micrograin solid carbide construction provides rigidity and dimensional stability

Compatibility

Designed as an OEM-style replacement or direct-use tooling for standard 1/4 inch straight-cylindrical shank collets and end mill holders on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the collet or holder and torque to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a production cut, and confirm cutting parameters match the workpiece material and coating recommendations.
