Accupro 12181741 Square End Mill 1 in 2 Flute Carbide Ticn

Product Description

The ACCUPRO 12181741 is a solid carbide square end mill designed for high-performance milling in demanding shop environments. Built from micrograin carbide and coated with titanium carbonitride (TiCN), this tool handles ferrous and non-ferrous materials with consistent edge retention. It features a 1 inch cutting diameter, a 3 inch length of cut, and a 40-degree helix angle that promotes efficient chip evacuation and smooth surface finishes. The extra-long overall length of 6 inches makes it well suited for deep-cavity work where standard-length tooling cannot reach. Machinists, tool-and-die makers, and CNC operators install this end mill in milling machines and machining centers.

This end mill is configured as a single-end, right-hand cutting, right-hand spiral tool with a spiral flute geometry. The extra-long reach classification and 3 inch length of cut make it appropriate for deep-pocket milling, slotting, and profiling operations where axial depth is a primary constraint. The 1 inch shank diameter provides rigid clamping in standard end mill holders, collet chucks, and hydraulic toolholders used on vertical and horizontal machining centers in both production and job-shop settings.

Key Features

• TiCN coating improves surface hardness and wear resistance compared to uncoated carbide
• 40-degree helix angle promotes efficient chip flow and reduces cutting forces
• Micrograin carbide substrate supports sharp edges and extended tool life
• Extra-long 6 inch overall length enables deep-reach milling applications
• Center-cutting geometry allows direct plunge entry into workpiece material
• Right-hand cut and right-hand spiral — compatible with standard spindle rotation on CNC mills

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 1 inch end mill holders, collet chucks, and hydraulic toolholding systems on CNC and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank fully into the holder to the recommended engagement depth and torque the retention screw or collet nut per the toolholder manufacturer specifications. Inspect the cutting edges and coating for chips or wear before each use; a damaged TiCN coating reduces tool life and surface finish quality.
