Accupro 12181744 Square End Mill 2 Flute Solid Carbide Ticn

Product Description

The ACCUPRO 12181744 is a solid carbide square end mill designed for precision milling operations in metal fabrication, toolroom work, and production machining environments. The cutter measures 0.125 inches in diameter with a matching 0.125-inch shank and delivers a 1-inch length of cut within a 3-inch overall length. A TiCN (titanium carbonitride) finish increases surface hardness and lubricity, extending tool life in ferrous and non-ferrous materials. The micrograin carbide substrate supports fine edge geometry and resists chipping under demanding feed rates. This is a single-end tool installed and operated by machinists and CNC programmers.

This end mill fits standard CNC machining centers, vertical mills, and manual knee mills accepting a 0.125-inch collet or toolholder. The extra-long 3-inch overall length suits applications requiring extended reach into deep pockets, stepped features, or fixtures with limited clearance. Right-hand cut and right-hand spiral flute configuration is compatible with conventional spindle rotation on most machining platforms. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action across a range of work materials.

Key Features

• TiCN coating improves hardness and reduces friction for extended tool life
• Micrograin solid carbide construction supports sharp, durable cutting edges
• 40-degree helix angle promotes chip evacuation and reduces chatter
• Centercutting geometry allows plunge entry into workpiece material
• Extra-long 3-inch OAL provides reach for deep-pocket and stepped-feature milling
• Right-hand cut and right-hand flute for standard spindle rotation compatibility

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills equipped with 0.125-inch collet toolholders or ER-series collet chucks accepting 1/8-inch shank end mills.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet or toolholder to the recommended gauge-line depth before torquing the collet nut to the toolholder specification. Inspect the collet for wear or runout before use, as excess runout at this diameter will accelerate edge wear and reduce surface finish quality.
