Accupro 95168661 Corner Radius End Mill 0.5in 5 Flute Altin

Product Description

The ACCUPRO 95168661 is a solid carbide corner radius end mill designed for high-performance milling in demanding machining environments. Built with five flutes and a 0.0600-inch corner radius, this tool delivers smooth surface finishes and extended tool life in hardened and abrasive materials. The AlTiN coating provides thermal resistance and wear protection at elevated cutting speeds. At 6 inches overall length with a 3.375-inch reach, this is a long-reach configuration suited for deep-cavity and extended-projection work. Right-hand cutting and right-hand flute direction are standard. The variable helix geometry reduces chatter and improves chip evacuation. A licensed machinist or CNC programmer typically selects and installs this tool.

This end mill is suited for CNC machining centers performing profiling, contouring, and finish milling in steel, stainless steel, cast iron, and other ferrous alloys where AlTiN coating provides optimal performance. The centercutting design allows plunge entry, and the long-reach body accommodates deep-pocket geometries and tall-wall features in production and job-shop environments. The 0.5-inch shank diameter fits standard ER and end mill holders with a 0.5-inch bore.

Key Features

• 0.0600-inch corner radius reduces stress concentrations and improves edge strength on profiled cuts
• AlTiN coating for high heat resistance and extended tool life in ferrous and hardened materials
• Five-flute design increases feed rate capability compared to four-flute tools of the same diameter
• Variable helix geometry dampens vibration and reduces chatter during deep-reach cuts
• Long-reach configuration with 3.375-inch reach length for deep-cavity accessibility
• Centercutting construction permits plunge milling without a pre-drilled entry point

Compatibility

Designed for use in standard 0.5-inch end mill holders, ER collet chucks, and shrink-fit holders on CNC vertical and horizontal machining centers configured for solid carbide end mills of this shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing any cutting tool. Seat the shank to the minimum recommended insertion depth in the tool holder to prevent runout and tool pull-out during cutting. Inspect the collet or end mill holder bore for wear or contamination before clamping, as holder condition directly affects runout and tool life.
