Accupro 12177086 Square End Mill 7/16 Inch 4 Flute Carbide

Product Description

The ACCUPRO 12177086 is a solid carbide square end mill designed for precision milling operations in metal, composites, and hard plastics. Built from micrograin carbide, it delivers consistent cutting performance and edge retention across a wide range of machining applications. The tool features a 7/16 inch cutting diameter with a 1 inch length of cut, a 4-flute spiral geometry, and a 40-degree helix angle that promotes smooth chip evacuation and reduces cutting forces. At 2-3/4 inches overall length with a matching 7/16 inch shank, it mounts directly in standard end mill holders or collet chucks. Machinists and tool-and-die professionals install this end mill on CNC mills and manual knee mills requiring a reliable uncoated general-purpose cutter.

This end mill is suited for slotting, profiling, and peripheral milling in general machining environments. The centercutting design allows direct plunge entry into workpiece material without pre-drilling. Right-hand cut and right-hand flute configuration make it compatible with standard CNC spindle rotation. The uncoated finish works well in applications where coolant is used and where coating buildup or galling is a concern, such as when machining aluminum or other non-ferrous materials. It is a single-end tool intended for production and job-shop use alike.

Key Features

• Micrograin solid carbide construction for high edge retention and wear resistance
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting geometry allows direct plunge milling without a pilot hole
• 4-flute spiral design balances material removal rate with surface finish quality
• Uncoated finish suitable for coolant-assisted machining of non-ferrous and ferrous materials
• Right-hand cut and right-hand flute for use with standard CNC and manual mill spindles

Compatibility

Designed as a general-purpose OEM-style solid carbide square end mill compatible with standard 7/16 inch end mill holders, ER collet chucks, and milling machine spindles accepting that shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the controller is in a safe state before installing or removing the tool. Seat the shank fully in the holder and torque set screws or collet nuts to the holder manufacturer specification. Inspect the cutting edges for chips or damage before each use and replace the tool if edge integrity is compromised.
