Accupro 12176837 Corner Radius End Mill 1 in 2 Flute Carbide

Product Description

The ACCUPRO 12176837 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hard metals. Built from micrograin carbide and coated with AlTiN (aluminum titanium nitride), this tool delivers extended tool life at elevated cutting temperatures. It features a 1 inch mill diameter, a 1-3/4 inch length of cut, and a 1/8 inch corner radius that reduces stress concentrations at part edges. The 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces. This is a single-end, centercutting tool, meaning it can be used for plunge entry as well as peripheral and slot milling. Machinists and tool-and-die professionals rely on this geometry for finishing and semi-finishing passes where edge quality and dimensional accuracy are critical.

This end mill is suited for CNC machining centers and manual mills where corner radius profiles are required on steel, stainless steel, titanium, and other hard or abrasive workpiece materials. The AlTiN coating makes it particularly effective in dry or near-dry cutting environments common in high-speed machining. Typical applications include die and mold work, aerospace components, and general precision part production where sharp internal corners are not permissible and a defined radius must be maintained consistently across production runs.

Key Features

• 1/8 inch corner radius reduces edge stress and improves surface finish at part transitions
• AlTiN coating provides heat resistance and extended tool life in hard and abrasive materials
• Micrograin solid carbide substrate delivers rigidity and resistance to chipping
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Right-hand cut, right-hand flute spiral for use with standard CNC spindle rotation

Compatibility

Designed as an OEM-style solid carbide corner radius end mill for use in standard CNC machining centers and manual milling machines accepting a 1 inch straight shank. No specific machine model compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank in a collet chuck or end mill holder to the manufacturer-recommended engagement depth, ensuring the shank diameter tolerance range of -0.0001 to -0.0004 inches is accounted for when selecting the holder. Confirm spindle direction matches the right-hand cutting orientation before operation. Inspect the tool for edge chipping or coating wear before each use and replace when tolerances can no longer be maintained.
