Accupro 312071 Corner Radius End Mill 3/16 in 5 Flute

Product Description

The ACCUPRO 312071 is a solid carbide corner radius end mill designed for precision milling in demanding machining environments. Built from micrograin solid carbide and coated with AlCrTiN, it delivers high heat resistance and extended tool life in hard and abrasive materials. The 3/16 inch diameter tool features 5 flutes with a right-hand cutting direction, a 38-degree helix angle, and a variable index design that reduces chatter and improves surface finish. With a 1/4 inch length of cut and an extended reach configuration, it is suited for tight-tolerance profiling and contouring work performed by machinists and toolroom operators.

This end mill is intended for use in CNC machining centers and manual mills where extended reach and corner radius geometry are required. The 1-1/8 inch reach length allows access to deeper pockets and stepped features without interference. The centercutting design permits plunge entry, adding versatility for slotting and ramping operations. It is a single-end tool packaged individually.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• AlCrTiN coating for high-temperature performance in hard materials
• 5-flute geometry with variable index to reduce harmonics and chatter
• Centercutting design allows direct plunge entry
• Extended reach with 1-1/8 inch reach length for deep-pocket access
• Right-hand flute spiral and cutting direction for standard CNC spindle use

Compatibility

Designed as an OEM-style replacement and standard production end mill for CNC machining centers and manual milling machines accepting a 3/16 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists following standard toolholder and collet procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Use a collet or end mill holder rated for the 3/16 inch shank diameter and verify runout with a dial indicator before production cuts. Follow machine manufacturer guidelines and applicable shop safety standards for speeds, feeds, and coolant application.
