Accupro 95169773 Square End Mill 1/4 in 7 Flute Carbide

Product Description

The ACCUPRO 95169773 is a 7-flute solid carbide square end mill designed for high-performance material removal in demanding machining applications. Built from micrograin carbide and coated with AlTiCrN for enhanced heat and wear resistance, this end mill runs at aggressive parameters where standard tooling falls short. The 1/4 inch diameter and 1-3/4 inch length of cut suit it to slotting, profiling, and finishing passes in hardened steels, stainless, and high-temp alloys. Right-hand cut and right-hand spiral flutes provide efficient chip evacuation. The 38-degree helix angle reduces cutting forces and improves surface finish. Machinists and tool room technicians are the primary users of this tool.

This end mill fits vertical and horizontal CNC machining centers and manual mills where a 1/4 inch shank is accommodated. The 4 inch overall length provides reach for deeper cavities while the single-end configuration keeps runout minimal. The HS series designation indicates this tool is engineered for high-speed machining strategies, making it well suited for die and mold work, aerospace component machining, and precision part production requiring tight tolerances and fine surface finishes.

Key Features

• 7-flute geometry increases feed rates and improves surface finish compared to standard 4-flute tools
• AlTiCrN coating provides high oxidation resistance for dry or minimum-quantity lubrication cutting
• Micrograin solid carbide substrate delivers rigidity and edge retention in tough materials
• 38-degree helix angle reduces cutting forces and improves chip flow
• Right-hand cut and right-hand flute spiral for compatibility with standard spindle rotation
• Single-end design minimizes runout for precision finishing work

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 1/4 inch round shank end mill. Part of the ACCUPRO HS series for high-speed machining applications.

Installation Notes

Installation is performed by qualified machinists or tool room technicians. Secure the shank fully into a collet or end mill holder to the recommended grip depth before torquing the retention mechanism. Inspect the collet and holder for runout before cutting. Never exceed the machine spindle speed or feed rate limits for the workpiece material and tool diameter combination.
