Accupro 12176838 Corner Radius End Mill 1 in 2 Flute Altin

Product Description

The ACCUPRO 12176838 is a single-end corner radius end mill designed for precision milling of ferrous and non-ferrous metals. Built from micrograin solid carbide and coated with AlTiN (Aluminum Titanium Nitride), it handles high-heat cutting environments where tool life and surface finish matter. The 1 inch cutting diameter, 1.75 inch length of cut, and 0.015 inch corner radius make it well-suited for profiling, slotting, and contouring operations that require a controlled edge break. The 40-degree helix angle improves chip evacuation and reduces cutting forces. This tool is installed by machinists and CNC operators in job shop and production environments.

This end mill is used in vertical and horizontal machining centers for medium to finishing passes on hardened steels, stainless alloys, and titanium. The centercutting geometry allows plunge entry into the workpiece. The right-hand flute direction and right-hand cutting direction are standard for conventional CNC setups. With a 1 inch shank diameter and 4 inch overall length, it fits standard collet and side-lock toolholders without an extension.

Key Features

• Micrograin solid carbide substrate for rigidity and wear resistance in high-temp alloys
• AlTiN coating extends tool life in dry and semi-dry cutting of ferrous materials
• 0.015 inch corner radius reduces chipping at the cutting edge and improves part finish
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting design permits direct plunge milling without a pre-drilled entry hole
• Single-end configuration with right-hand cut and right-hand spiral flute direction

Compatibility

Designed as an OEM-style replacement or direct-use end mill for CNC machining centers accepting a 1 inch straight shank in standard collet, Weldon, or milling chuck toolholders.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state per shop lockout/tagout procedures. Ensure the shank is seated to the full recommended grip depth in the toolholder and that runout is verified with a dial indicator before the first cut. Consult the toolholder manufacturer's torque specifications for set screws or collet nuts. Do not exceed the tool's rated depth of cut or feed rate for the workpiece material.
