Accupro 12177372 Corner Radius End Mill 6mm 2 Flute Carbide

Product Description

The ACCUPRO 12177372 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hard materials. Built from micrograin carbide and coated with AlTiN (aluminum titanium nitride), it handles high-heat applications where tool life and dimensional accuracy are critical. The 6 mm cutting diameter pairs with a 1 mm corner radius that reduces stress concentrations and chip load at the cutting edge. With a 30-degree helix angle and right-hand spiral flutes, it evacuates chips efficiently in both climb and conventional milling passes. Centercutting geometry allows plunge entry directly into the workpiece. Machinists and toolroom operators use this end mill on CNC machining centers and manual knee mills.

This end mill is suited for profiling, slotting, and peripheral milling where a radiused corner is required for part geometry or to improve surface finish and tool life at the edge. The 6 mm length of cut and 16 mm reach length make it appropriate for shallow-to-moderate depth passes in pockets and contours. The single-end configuration and extended reach design keep it stable at working depth. It is commonly used in aerospace, die and mold, and precision parts machining on materials that benefit from AlTiN coating performance.

Key Features

• Micrograin solid carbide substrate for rigidity and wear resistance
• AlTiN coating provides high-temperature oxidation resistance for dry and high-speed machining
• 1 mm corner radius reduces edge chipping and improves part surface finish at corners
• 30-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Extended reach geometry with 16 mm reach length for access to moderate-depth features

Compatibility

Designed as an OEM-style solid carbide corner radius end mill for use in CNC machining centers and manual mills accepting a 6 mm shank diameter collet or toolholder.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding practices. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing or seating the end mill. Use a properly sized ER collet or shrink-fit holder matched to the 6 mm shank diameter and verify runout before beginning a cut. Do not exceed the tool manufacturer's recommended depth of cut or feed rate for the workpiece material.
