Accupro 12185046 Square End Mill 3/8 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12185046 is a square end mill designed for precision milling operations in metal and alloy workpieces. It features a 0.375-inch mill diameter, a 0.75-inch length of cut, and a 3.5-inch overall length, making it suited for standard-depth slotting, profiling, and peripheral milling tasks. Constructed from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it handles elevated cutting temperatures and resists wear in ferrous and hardened materials. The 2-flute configuration and 40-degree helix angle promote efficient chip evacuation. This tool is installed and operated by machinists and CNC programmers in job shop, toolroom, and production environments.

This end mill fits standard milling applications including slotting, contouring, and full-width cuts on ferrous metals, stainless steel, titanium, and similar hard materials. The centercutting geometry allows plunge entry directly into the workpiece. The AlTiN coating extends tool life at higher surface footage compared to uncoated carbide. Its right-hand cut and right-hand spiral flute configuration suits conventional CNC machining centers and manual knee mills using standard toolholding. The 0.375-inch shank fits common collet chucks, end mill holders, and shrink-fit toolholding systems.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for high-temperature performance and extended tool life
• 40-degree helix angle for smooth cutting action and efficient chip evacuation
• Centercutting design allows direct plunge milling into the workpiece
• Right-hand cut with right-hand spiral flute for standard CNC and manual milling setups
• Double-end geometry provides two usable cutting ends, extending service life

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual milling machines accepting a 0.375-inch shank via collet chuck, end mill holder, or shrink-fit toolholding.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with rotating cutting tool safety. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify collet or toolholder condition and proper shank seating depth before operation. Follow machine manufacturer torque specifications for drawbar and toolholder fasteners, and confirm runout with a dial indicator before beginning a cut.
