Accupro 12179661 Corner Radius End Mill 1/8 in 3 Flute

Product Description

The ACCUPRO 12179661 is a solid carbide corner radius end mill designed for precision milling operations in metal cutting and machining applications. With a 1/8 inch diameter and a 0.01 inch corner radius, this tool produces smooth transitions and reduces stress concentrations at milled corners. The 3-flute, right-hand spiral geometry with a 35-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiCN coating increases surface hardness and wear resistance, extending tool life in ferrous and non-ferrous materials. Licensed machinists and CNC operators working in job shops, toolrooms, and production environments are the primary users of this end mill.

This end mill is suited for stub-length milling operations where rigidity and minimal deflection are critical. The centercutting design allows for plunge milling as well as peripheral cuts. With a 1/4 inch length of cut and a 1-1/2 inch overall length, it is well-matched to shallow pocket milling, contouring, and profiling operations on CNC machining centers and manual mills. The 1/8 inch shank diameter is compatible with standard collets and end mill holders of the same bore size.

Key Features

• Solid carbide micrograin construction for high rigidity and dimensional stability
• TiCN coating improves wear resistance and reduces built-up edge in steel and stainless applications
• 0.01 inch corner radius reduces corner chipping and stress concentrations in milled profiles
• 3-flute right-hand spiral with 35-degree helix for efficient chip evacuation
• Centercutting geometry enables plunge entry without a pre-drilled hole
• Stub length design increases tool stiffness and reduces deflection in tight-tolerance cuts

Compatibility

Designed for use with standard 1/8 inch bore collets and end mill holders on CNC machining centers and manual vertical mills. Confirm holder bore and runout tolerance before use.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the collet or holder to the recommended engagement depth and torque the drawbar or nut to the holder manufacturer specification. Inspect the cutting edges and coating for chips or damage before each use.
