Accupro 12177338 Corner Radius End Mill 1.2mm 2 Flute

Product Description

The ACCUPRO 12177338 is a solid carbide corner radius end mill designed for high-precision milling of tight-tolerance features in hard and abrasive materials. With a 1.2 mm cutting diameter and a 0.1 mm corner radius, this tool produces fine detail work where edge integrity and dimensional accuracy are critical. The AlTiN coating provides excellent heat resistance and extended tool life in demanding cutting environments. The micrograin carbide substrate supports sharp edge retention and consistent performance in ferrous and non-ferrous applications. This tool is intended for use by machinists and CNC tooling professionals working in precision manufacturing, mold and die, and aerospace component production.

This end mill is suited for finishing passes, profiling, and slotting operations where a small-diameter, corner-radiused tool is required. The single-end, centercutting design allows for plunge entry and versatile toolpath strategies. Extended reach geometry, with a 20 mm reach length and 57 mm overall length, supports applications where clearance is required between the spindle and workpiece. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC milling setups.

Key Features

• 1.2 mm cutting diameter with 0.1 mm corner radius for precise edge forming
• AlTiN coating for high heat resistance and extended tool life in hard materials
• Micrograin solid carbide substrate for sharp, durable cutting edges
• Centercutting design allows direct plunge entry
• Extended reach with 20 mm reach length and 57 mm overall length
• 30-degree helix angle promotes efficient chip evacuation and smooth cutting action

Compatibility

Designed as an OEM-style replacement or direct-use end mill compatible with CNC machining centers and manual mills accepting a 6 mm straight shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully powered down and locked before changing tooling. Secure the 6 mm shank in a collet or end mill holder rated for the shank diameter, and verify runout with a dial indicator before beginning a cut. Follow all applicable machine tool safety procedures and manufacturer feed and speed guidelines for the workpiece material.
