Accupro 12183119 Corner Radius End Mill 5/8 in 4 Flutes Ticn

Product Description

The ACCUPRO 12183119 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 5/8 inch diameter, a 2-1/8 inch length of cut, and a 0.03 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in aggressive profiling and slotting applications. The TiCN coating adds hardness and lubricity at the cutting surface, helping the tool resist heat and abrasion during high-speed cutting. With 4 right-hand spiral flutes and a centercutting design, this end mill handles both ramping and plunging without requiring a pre-drilled entry point. It is sold as a single-end tool in micrograin carbide for consistent edge geometry.

This end mill is suited for machining operations in metalworking shops, tool rooms, and production environments. Its long-reach geometry, with a 4-5/8 inch overall length and 2-1/8 inch length of cut, makes it appropriate for deep-pocket milling, contour profiling, and finish passes where a standard-length tool cannot reach. The 40-degree helix angle promotes smooth chip evacuation and reduces chatter on finishing cuts. It is installed in CNC machining centers and manual mills by machinists and tool-and-die professionals working to tight dimensional tolerances.

Key Features

• 0.03 inch corner radius reduces edge chipping and stress at part corners during profiling
• TiCN coating increases surface hardness and wear resistance for extended tool life
• 4 right-hand spiral flutes with 40-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry without pilot drilling
• Micrograin solid carbide construction maintains edge sharpness under high cutting loads
• Long-reach geometry with 4-5/8 inch OAL supports deep-pocket and cavity milling

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for 5/8 inch collet or end mill holder systems used in CNC machining centers and conventional vertical mills.

Installation Notes

Installation is performed by machinists using a 5/8 inch end mill holder, collet chuck, or shrink-fit toolholder. Ensure the holder and spindle taper are clean and free of chips or debris before seating the tool. Torque retention screws or collet nuts to the toolholder manufacturer specification. Follow shop safety procedures and machine guarding requirements before engaging the spindle.
