Accupro 12177418 Square End Mill 7/16 in 6 Flute Carbide

Product Description

The ACCUPRO 12177418 is a 6-flute solid carbide square end mill designed for high-performance milling in ferrous and non-ferrous materials. It carries an AlTiN (aluminum titanium nitride) coating that extends tool life under high-heat cutting conditions. The mill features a 45-degree helix angle with a spiral flute geometry that promotes efficient chip evacuation and reduces chatter. At 7/16 inch in diameter with a 1 inch length of cut, this end mill is suited for slotting, profiling, and peripheral milling operations. It is installed and operated by machinists and tool-and-die professionals working with CNC machining centers and manual milling equipment.

This end mill is appropriate for use in production and job-shop environments where consistent dimensional accuracy is required. The micrograin carbide substrate provides rigidity and wear resistance suitable for hardened steels, stainless alloys, and cast iron. The centercutting configuration allows direct plunge entry into the workpiece. Right-hand cut and right-hand flute orientation are standard for conventional CNC spindle rotation. The 7/16 inch shank diameter matches the 7/16 inch cutter diameter, maintaining a straight-shank profile for use in standard collet chucks and end mill holders.

Key Features

• Solid micrograin carbide construction for rigidity and extended tool life
• AlTiN coating provides heat resistance and reduces friction at high cutting speeds
• 6-flute design increases feed rates and improves surface finish in finishing passes
• 45-degree helix angle promotes smooth chip flow and reduces axial cutting forces
• Centercutting geometry allows direct plunge milling without a pre-drilled pilot hole
• Right-hand cut, right-hand flute — compatible with standard CNC and manual mill spindle rotation

Compatibility

Designed as a direct-fit replacement or standard tooling selection for 7/16 inch straight-shank collet chucks, end mill holders, and hydraulic chucks used on CNC machining centers and knee mills. No specific OEM model compatibility was stated in the product data.

Installation Notes

Installation is performed by a machinist or tooling technician. The machine spindle must be fully stopped and the tool holder must be secured in a vise or holder block before inserting or removing the end mill. Ensure the shank is clean and free of burrs before seating it in the collet or holder to maintain runout within tolerance. Verify spindle speed, feed rate, and depth of cut against the material being machined before engaging the cutter; exceeding recommended parameters can cause premature tool failure or workpiece damage.
