Accupro 12177334 Corner Radius End Mill 1.2mm 2 Flute

Product Description

The ACCUPRO 12177334 is a solid carbide corner radius end mill designed for precision machining in tight-tolerance applications. It features a 1.2 mm cutting diameter with a 0.1 mm corner radius and a 1.2 mm length of cut. The tool is coated with AlTiN (aluminum titanium nitride) for heat resistance and extended tool life in ferrous and hardened materials. With a 30-degree helix angle and right-hand spiral flutes, it delivers efficient chip evacuation and smooth cutting action. Machinists and tool-and-die professionals use this end mill for micro-milling, die work, and fine-detail profiling where edge integrity and dimensional accuracy are critical.

This end mill is suited for CNC machining centers and milling machines handling small-feature work in steel, stainless steel, cast iron, and hardened alloys. The 6 mm shank diameter fits standard ER collet systems commonly used in high-speed spindles. Extended reach geometry, with a 7 mm reach length and 57 mm overall length, allows access to recessed features and deep pocket walls without interference. The centercutting design permits direct plunge entry, adding flexibility to toolpath programming.

Key Features

• 1.2 mm cutting diameter with 0.1 mm corner radius for fine-detail profiling
• AlTiN coating provides thermal resistance and extends tool life in hardened and ferrous materials
• Solid micrograin carbide construction for rigidity and wear resistance at small diameters
• 30-degree helix angle promotes smooth cutting and efficient chip evacuation
• Centercutting design allows direct plunge milling
• Extended reach with 7 mm reach length for recessed feature access

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for CNC milling applications requiring a 6 mm shank and 1.2 mm cutting diameter.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Secure the 6 mm shank in a properly sized ER collet or end mill holder and torque to the machine spindle manufacturer specification. Verify runout with a dial indicator before cutting to protect the small-diameter tool from premature breakage. Always confirm spindle speed and feed rate in the CAM program or machining data reference before engaging the workpiece.
