Accupro 12177416 Square End Mill 3/8 in 6 Flute Solid Carbide

Product Description

The ACCUPRO 12177416 is a 6-flute solid carbide square end mill designed for high-performance milling in demanding shop environments. It carries a 3/8 inch cutter diameter with a 1-1/2 inch length of cut and a 4 inch overall length. The micrograin carbide substrate is finished with an AlTiN (aluminum titanium nitride) coating, which supports elevated cutting temperatures and extends tool life in ferrous and hardened materials. The 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces. Centercutting geometry allows plunge milling as well as conventional peripheral cuts. Machinists and tool-and-die professionals select this end mill for finishing and semi-finishing operations where tight tolerances and surface finish matter.

This end mill suits CNC machining centers and manual knee mills running steel, stainless, cast iron, and similar hard materials. The spiral flute design and right-hand cut with right-hand flute configuration follow standard conventions for most vertical milling setups. It is well suited to applications requiring longer reach into pockets or slots where a shorter tool would not clear the workpiece. The single-end configuration is standard for precision work requiring consistent runout control.

Key Features

• 6-flute geometry increases feed rate capability and improves surface finish compared to 4-flute designs
• AlTiN coating extends tool life in high-heat cutting environments and reduces built-up edge on ferrous materials
• 45-degree helix angle promotes aggressive chip evacuation and lowers radial cutting forces
• Centercutting design enables plunge entry without a pre-drilled hole
• Micrograin solid carbide substrate provides rigidity and wear resistance at the cutting edge
• Right-hand cut and right-hand flute configuration compatible with standard spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard 3/8 inch collet or end mill holder setups on CNC and manual milling machines.

Installation Notes

Installation is performed by a machinist or toolroom technician. Secure the shank in a properly sized collet, end mill holder, or shrink-fit holder rated for the 3/8 inch shank diameter, and verify runout before starting a cut. Power down and lock out the spindle before changing or adjusting any tooling. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and depth of cut.
