Accupro 12181363 Square End Mill 19/64 in 2 Flute Carbide Ticn

Product Description

The ACCUPRO 12181363 is a solid carbide square end mill designed for precision milling operations in metal-cutting and machining applications. This two-flute tool measures 0.2969 inches (19/64 inch) in cutting diameter with a 0.75-inch length of cut and a 5/16-inch shank diameter. The micrograin carbide substrate provides hardness and wear resistance, while the TiCN (titanium carbonitride) coating reduces friction and extends tool life in demanding cuts. At 2.5 inches overall length, it fits standard toolholders used in CNC machining centers and manual mills. Installation and operation are performed by machinists and tool-and-die professionals in production and job-shop environments.

This end mill suits ferrous and non-ferrous material removal, profiling, slotting, and side-milling operations. The regular-length designation makes it appropriate for general-purpose work where extended reach is not required. The centercutting geometry allows plunge entry directly into the workpiece, enabling ramping and plunge-milling tool paths. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action in a variety of materials.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• TiCN coating reduces friction and extends tool life compared to uncoated carbide
• 40-degree helix angle for efficient chip evacuation and smooth cutting action
• Centercutting geometry allows direct plunge entry into the workpiece
• Right-hand cut, right-hand spiral flute configuration for standard spindle rotation
• Regular-length design provides stiffness and minimizes deflection in typical applications

Compatibility

Designed for use in CNC machining centers, knee mills, and manual milling machines accepting a 5/16-inch straight shank. Compatible with standard collet chucks, end mill holders, and shrink-fit toolholders rated for that shank diameter.

Installation Notes

Install and remove end mills only with the machine spindle at a full stop and the machine locked out per applicable shop safety procedures. Ensure the shank is fully seated in the toolholder to the minimum engagement depth before tightening. Verify runout with a dial indicator after installation to confirm the tool is seated correctly. Follow the tool manufacturer's recommended speeds and feeds for the specific workpiece material and apply cutting fluid or coolant as appropriate.
