Accupro 12176675 Corner Radius End Mill 0.2188 in 3 Flute

Product Description

The ACCUPRO 12176675 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. Built from micrograin solid carbide with a TiCN (Titanium Carbonitride) coating, it delivers extended tool life and improved wear resistance in ferrous and non-ferrous materials. The 0.2188-inch cutting diameter and 0.0200-inch corner radius reduce stress concentrations at part edges, producing clean, radiused transitions without secondary operations. A 35-degree helix angle promotes efficient chip evacuation and smoother cutting action. This tool is sold as a single-end, centercutting end mill, meaning it can be plunged directly into workpiece material.

This end mill fits standard CNC machining centers, vertical mills, and manual milling machines equipped with a 1/4-inch collet or toolholder. The stub-length geometry, with a 3/8-inch length of cut and 2-inch overall length, provides rigidity for finish milling, contouring, slotting, and profiling in tight-clearance setups. It is suited for shops and toolrooms performing precision detail work in steel, stainless, cast iron, and similar materials where corner integrity and dimensional accuracy are critical.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• TiCN coating improves surface hardness and reduces friction at the cutting edge
• 0.0200-inch corner radius reduces edge chipping and stress at workpiece corners
• 35-degree helix angle promotes smooth cutting and efficient chip flow
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand flute direction and right-hand cutting for standard spindle rotation

Compatibility

Designed for use in any milling machine or CNC machining center equipped with a 1/4-inch collet, end mill holder, or compatible toolholder accepting a 1/4-inch shank.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or toolholder to the minimum insertion depth recommended by the toolholder manufacturer, and verify runout with a dial indicator before beginning cuts. Follow applicable shop safety procedures for high-speed rotating cutting tools.
