Accupro 12176923 Square End Mill 3/8 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12176923 is a solid carbide square end mill designed for precision milling operations in metal and hard material applications. It features a 3/8-inch cutting diameter, a 9/16-inch length of cut, and a stub-length overall length of 2 inches. The micrograin carbide substrate paired with a TiCN coating provides elevated wear resistance and heat tolerance, making this tool well suited for ferrous and non-ferrous cutting. The 4-flute, right-hand spiral configuration with a 40-degree helix angle promotes efficient chip evacuation and a smooth cutting action. Centercutting geometry allows for plunge entry. Licensed machinists and CNC operators are the primary installers of this tool.

This end mill is suited for use in vertical machining centers, CNC mills, and manual knee mills where stub-length rigidity is preferred to minimize deflection in tight-clearance setups. The 3/8-inch shank diameter fits standard ER collet chucks and end mill holders commonly found in production and job-shop environments. It is appropriate for milling slots, profiles, pockets, and contour work in steel, stainless steel, cast iron, and similar materials where TiCN coating performance is advantageous.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• TiCN finish improves surface lubricity and extends tool life in ferrous materials
• 40-degree helix angle promotes aggressive chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge milling without a pre-drilled pilot hole
• Stub-length OAL of 2 inches maximizes rigidity and minimizes runout in shallow-depth operations
• Right-hand cut and right-hand flute configuration for standard spindle use

Compatibility

Designed for use in standard 3/8-inch ER collet chucks, shrink-fit holders, and end mill holders on CNC and manual milling machines. No specific OEM system compatibility was provided by the manufacturer for this part number.

Installation Notes

This tool is installed and operated by machinists and CNC programmers following standard toolholding procedures. Ensure the spindle is fully stopped and locked out before changing tools. Secure the shank to the full recommended insertion depth within the holder to minimize overhang and vibration. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.
