Accupro 12179064 Square End Mill 1/8 in 4 Flute Carbide

Product Description

The ACCUPRO 12179064 is a solid carbide square end mill designed for precision milling operations across a range of ferrous and non-ferrous materials. With a 0.1250 inch mill diameter, a 4-flute spiral configuration, and a 40-degree helix angle, this tool delivers clean cuts and efficient chip evacuation in demanding machining environments. The nACRo coating provides enhanced wear resistance and heat reduction at the cutting edge. It is centercutting, allowing direct plunge entry. Machinists and tool-and-die professionals working on CNC mills and machining centers will find this end mill suited to tight-tolerance finishing and profiling passes.

This end mill is built for single-end use with a right-hand cut and right-hand flute orientation, which is the standard configuration for most vertical and horizontal CNC machining centers. The 0.7500 inch length of cut and 3.0000 inch overall length make it well-suited for shallow-to-moderate depth profiling, slotting, and contouring in both production and job-shop settings. The micrograin carbide substrate supports high-speed operation and maintains edge integrity longer than standard carbide grades under consistent cutting loads.

Key Features

• Solid micrograin carbide construction for extended tool life and edge retention
• nACRo coating reduces friction and thermal buildup at the cutting edge
• 40-degree helix angle promotes smooth cutting action and effective chip removal
• Centercutting design allows direct plunge milling without pre-drilling
• Right-hand cut and right-hand flute for standard CNC machining center compatibility
• Mill diameter tolerance of +0.000 / -0.002 inches ensures consistent fit and finish

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard CNC milling applications requiring a 1/8 inch shank and 1/8 inch cutting diameter.

Installation Notes

Installation should be performed by a qualified machinist familiar with toolholder runout requirements and proper collet or end mill holder torque procedures. Verify that the toolholder bore matches the 0.1250 inch shank diameter before seating the tool. Ensure the machine spindle is fully stopped and locked out before changing tooling. Do not exceed the rated depth of cut for the material being machined, and confirm tool projection length is minimized to reduce deflection.
