Accupro 12177423 Square End Mill 1/2 in 6 Flute Carbide

Product Description

The ACCUPRO 12177423 is a 6-flute solid carbide square end mill designed for precision milling operations in metal cutting and finishing applications. Built from micrograin carbide, it delivers a 0.5000-inch cutting diameter and a 2-inch length of cut, with an overall length of 4 inches and a matching 1/2-inch shank diameter. The 45-degree helix angle promotes efficient chip evacuation and smooth cutting action. This is a single-end, centercutting tool, meaning it can be plunged directly into a workpiece. The bright uncoated finish makes it suitable for general-purpose use across a range of ferrous and non-ferrous materials. Machinists and toolmakers in job shops, production facilities, and maintenance environments are the primary users.

This end mill fits standard CNC machining centers, knee mills, and manual milling machines that accept a 1/2-inch tool shank. The 6-flute geometry provides a higher feed rate capability compared to 4-flute designs of the same diameter, making it well suited for finishing passes and light to moderate material removal in steel, cast iron, and aluminum. The right-hand cut and right-hand spiral flute configuration is the standard orientation compatible with conventional spindle setups. The extended reach designation does not apply to this tool, keeping the tool profile compact and rigid for close-tolerance work.

Key Features

• 6-flute design supports higher feed rates and improved surface finish compared to fewer-flute alternatives
• 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Centercutting geometry allows direct plunge entry without pre-drilling
• Micrograin solid carbide construction provides hardness and wear resistance for extended tool life
• Bright uncoated finish suitable for general-purpose milling across a variety of workpiece materials
• Right-hand cut and right-hand flute configuration matches standard CNC and manual mill spindle rotation

Compatibility

Designed as a standard 1/2-inch shank square end mill compatible with any milling machine or machining center spindle, collet, or tool holder accepting a 1/2-inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Power down and lock out the machine spindle before installing or changing tooling. Seat the shank fully into the collet or end mill holder to the recommended engagement depth before tightening, and verify runout with an indicator before commencing a cut. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and depth of cut.
