Accupro 12181450 Square End Mill 29/64 in 2 Flute Carbide

Product Description

The ACCUPRO 12181450 is a solid carbide square end mill designed for precise milling operations in metal, alloy, and hard material applications. With a 29/64 inch (0.4531 inch) cutting diameter and a 2-flute spiral design, it delivers efficient chip evacuation and clean edge finishes in a variety of cut types. The TiCN coating increases surface hardness and reduces friction at the cutting edge, extending tool life in abrasive materials. A 40-degree helix angle promotes smooth cutting action and reduces chatter during full-depth passes. This end mill is single-end, centercutting, and built from micrograin solid carbide for dimensional stability under thermal load.

This end mill is suited for CNC machining centers, manual mills, and production milling environments where close-tolerance slotting, profiling, and plunge operations are required. The 1 inch length of cut and 3 inch overall length make it practical for standard-depth pocket milling and peripheral profiling on ferrous and non-ferrous workpieces. Machinists and tool-and-die professionals handling precision stock removal will find this geometry well-matched to medium-to-hard materials. Right-hand cut and right-hand flute orientation are standard for conventional CNC spindle setups.

Key Features

• 29/64 inch (0.4531 inch) cutting diameter with a tolerance of +0.000 / -0.002 inches for consistent fit
• TiCN coating for improved wear resistance and reduced built-up edge in hard and abrasive materials
• 40-degree helix angle promotes smooth chip flow and reduces cutting forces
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Micrograin solid carbide substrate delivers rigidity and resistance to deflection
• 2-flute spiral geometry suited for slotting and profiling with adequate chip clearance

Compatibility

Designed as a standard-geometry replacement or working end mill for CNC machining centers and manual knee mills accepting a 1/2 inch shank diameter collet or end mill holder.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Secure the 1/2 inch shank in a properly sized collet, end mill holder, or shrink-fit toolholder, ensuring full seating depth before torquing the retention mechanism. Confirm spindle runout is within acceptable limits before engaging the cut, as excessive runout accelerates coating wear and reduces dimensional accuracy. Always power down and lock out the spindle before changing tooling.
