Accupro 12179683 Corner Radius End Mill 0.5in 3 Flute Ticn

Product Description

The ACCUPRO 12179683 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 0.5 inch diameter with a 0.02 inch corner radius, a 1.25 inch length of cut, and a 3 inch overall length. The three-flute, right-hand spiral geometry paired with a 35-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiCN (Titanium Carbonitride) coating improves surface hardness and wear resistance, extending tool life in demanding applications. This end mill is center-cutting, allowing direct plunge entry into workpiece material.

This end mill is suited for profiling, slotting, and finishing operations on ferrous and non-ferrous metals where a controlled corner radius is required to reduce stress concentrations and improve part geometry. It is a single-end tool with a 0.5 inch shank diameter, making it compatible with standard end mill holders and collet chucks found in CNC machining centers and manual knee mills. Typical users include machinists and toolroom operators in job shop and production environments.

Key Features

• 0.02 inch corner radius reduces stress risers and improves finish at part edges
• TiCN coating increases surface hardness and wear resistance compared to uncoated carbide
• 35-degree helix angle promotes smooth chip flow and reduces cutting forces
• Center-cutting design allows plunge milling without a pre-drilled entry hole
• Micrograin solid carbide substrate supports tight tolerances and rigidity
• Right-hand flute direction and right-hand cutting for standard spindle rotation

Compatibility

Designed as a direct-fit replacement or standard tooling selection for 0.5 inch end mill holders, ER collet chucks, and Weldon-style tool holders used in CNC machining centers and manual milling machines accepting 0.5 inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the holder to the recommended engagement depth and torque set screws or collet nuts to the holder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates wear on carbide tooling.
