Accupro 12177362 Corner Radius End Mill 4mm 2-flute Carbide

Product Description

The ACCUPRO 12177362 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and tooling applications. It features a 4 mm cutting diameter with a 0.25 mm corner radius, a 4 mm length of cut, and an AlTiN (aluminum titanium nitride) coating that extends tool life at elevated cutting temperatures. The micrograin carbide substrate supports sharp edge retention and dimensional stability. With a 6 mm shank diameter and 57 mm overall length, this single-end, centercutting tool is suited for finish milling, contouring, and ramping operations in hardened and abrasive workpiece materials.

This end mill is used in CNC machining centers for light to medium stock removal and finishing passes on ferrous and non-ferrous metals, including hardened steels and stainless. The centercutting geometry allows direct plunge entry. The 30-degree helix angle promotes smooth chip evacuation in slotting, profiling, and peripheral milling operations. Extended reach of 30 mm provides clearance in deep pocket and tall workpiece setups. It is installed and run by CNC machinists and tool-and-die professionals.

Key Features

• AlTiN coating for high-temperature resistance and extended tool life in ferrous materials
• Micrograin solid carbide substrate for sharp, stable cutting edges
• 0.25 mm corner radius reduces stress concentration and improves corner finish quality
• Centercutting design allows direct plunge entry without pre-drilled pilot holes
• 30-degree right-hand helix promotes efficient chip evacuation in slotting and profiling
• Extended reach of 30 mm suitable for deep pocket and tall fixturing setups

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill compatible with standard CNC milling tool holders accepting a 6 mm shank diameter.

Installation Notes

Installation is performed by a qualified CNC machinist or tooling technician. Seat the 6 mm shank fully and evenly in a collet or end mill holder and torque the retention mechanism per the tool holder manufacturer specification. Confirm runout with a dial indicator before initiating a cut. Do not exceed the manufacturer-recommended cutting parameters for the workpiece material and coating type.
