Accupro 12178801 Square End Mill 31/64 Inch 2 Flute Carbide

Product Description

The ACCUPRO 12178801 is a solid carbide square end mill designed for precise milling operations in metal fabrication and machining environments. With a 31/64 inch (0.4844 inch) mill diameter and a 5/8 inch length of cut, this tool handles slotting, profiling, and peripheral milling in ferrous and non-ferrous materials. The nACRo coating improves wear resistance and reduces friction at the cutting edge. A 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces. Licensed machinists and CNC programmers working in job shops, production facilities, and toolrooms are the primary users of this end mill.

This end mill is suited for use in CNC machining centers and manual mills where a right-hand cut, right-hand spiral flute configuration is required. The centercutting design allows plunge entry directly into a workpiece. Micrograin carbide construction supports high-speed feeds and speeds in demanding applications. It is appropriate for finish and semi-finish milling passes on steel, stainless, aluminum, and similar materials where tight dimensional tolerances are required.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• nACRo finish coating reduces friction and extends tool life in ferrous materials
• 40-degree helix angle promotes efficient chip evacuation
• Centercutting geometry allows direct plunge entry into workpiece
• Right-hand cut and right-hand spiral flute for standard CNC and manual mill compatibility
• Mill diameter tolerance of +0.000 / -0.002 inch for consistent fit and finish

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 1/2 inch collet or end mill holder setups on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked before changing tooling. Seat the 1/2 inch shank fully into the collet or tool holder and torque to the tool holder manufacturer specification. Confirm runout with a dial indicator before beginning a cut to protect both the tool and the workpiece.
