Accupro 12179063 Square End Mill 1 in 4 Flute Carbide

Product Description

The ACCUPRO 12179063 is a solid carbide square end mill designed for precision milling in demanding production and job-shop environments. Built from micrograin carbide stock, it carries a 1-inch cutting diameter with a 2-inch length of cut and a 6-inch overall length. The four-flute configuration with a 40-degree spiral helix promotes efficient chip evacuation while maintaining a stable cut. An nACRo finish extends tool life in high-temperature cutting conditions. Centercutting geometry allows plunge entry, giving machinists added flexibility in pocketing and profiling operations. This tool is installed by machinists and CNC operators working on milling machines and machining centers.

This end mill is suited for general-purpose and high-performance milling of ferrous and non-ferrous materials where a right-hand cut with right-hand flute is required. The 1-inch shank diameter matches standard ER and CAT toolholders common in vertical and horizontal machining centers. Its extended-reach designation is listed as no, making it a standard-reach tool appropriate for setups where workpiece clearance is not a limiting factor. Typical applications include face milling, contouring, slotting, and full-width roughing passes on steel, stainless, and alloy workpieces.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• nACRo coating for extended tool life in high-heat cutting conditions
• 40-degree helix spiral flute for improved chip flow and surface finish
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut with right-hand flute — standard configuration for most CNC milling setups
• 1-inch shank diameter with close-tolerance shank (-0.0001 / -0.0004 inches) for secure toolholder seating

Compatibility

Designed as an OEM-style replacement or direct-fit tool for standard 1-inch bore milling toolholders, including ER collet chucks, shrink-fit holders, and side-lock holders used on vertical and horizontal CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator following the machine builder's toolholder torque and runout specifications. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the toolholder to the recommended gauge-line depth and verify runout with a dial indicator before commencing cuts. Do not exceed the tool's rated depth of cut or feed rate for the workpiece material being machined.
