Accupro 12177404 Square End Mill 3/16 in 6 Flute Carbide

Product Description

The ACCUPRO 12177404 is a solid carbide square end mill designed for high-performance milling in demanding shop environments. Built from micrograin carbide and coated with AlTiN for heat and wear resistance, this tool handles hard materials and elevated cutting speeds with consistency. It features a 3/16 inch cutting diameter, a 5/16 inch length of cut, and a 6-flute geometry with a 45-degree helix angle for efficient chip evacuation and smooth surface finishes. Single-end configuration and right-hand cutting direction make it a straightforward replacement for standard finishing and semi-finishing operations on CNC machining centers and manual mills.

This end mill is suited for ferrous and non-ferrous machining in both production and job-shop settings. The 6-flute design supports higher feed rates compared to 4-flute tools, making it a practical choice when cycle time and surface finish both matter. The AlTiN coating extends tool life in harder steels, stainless, and cast iron. The 3/16 inch shank diameter matches the cutting diameter, allowing direct collet chuck mounting without adapters in standard toolholding systems. Overall length is 2 inches, keeping the tool compact and rigid for shallow-to-medium depth applications.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• AlTiN coating for thermal resistance and extended tool life in hard materials
• 6-flute spiral geometry with 45-degree helix angle for efficient chip flow
• Centercutting capable, allowing plunge entry into workpieces
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• Tight mill diameter tolerance of +0.000/-0.002 inches for precise fit and finish

Compatibility

Designed as a direct-fit replacement or standard-spec square end mill for CNC machining centers and manual milling machines using 3/16 inch collet or end mill holders.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the shank fully into the collet or holder before torquing the retention nut to the toolholder specification. Inspect the shank and collet bore for chips or debris before mounting to avoid runout issues.
