Accupro 12185138 Square End Mill 3/8 in 4 Flute Carbide Ticn

Product Description

The ACCUPRO 12185138 is a double-end square end mill designed for precision milling operations in metal and composite materials. Built from micrograin solid carbide, it delivers hardness and wear resistance well beyond high-speed steel tooling. The TiCN (Titanium Carbonitride) coating further extends tool life by reducing friction and heat buildup at the cutting edge. With a 3/8 inch cutting diameter, 3/4 inch length of cut, and a 40-degree helix angle, this end mill is suited for aggressive side milling, slotting, and finishing passes. It is centercutting, allowing direct plunge entry into workpiece material. Machinists, toolmakers, and CNC operators install and run this tool in vertical and horizontal milling machines and machining centers.

This end mill is used in job shops, production facilities, and tool rooms for milling ferrous and non-ferrous metals, hardened steels, stainless steels, and similar materials. The double-end configuration provides two usable cutting ends, extending overall tool value per unit. The spiral flute geometry promotes efficient chip evacuation, reducing the risk of chip packing in slots and pockets. The 3/8 inch shank diameter allows direct installation into standard collets, end mill holders, and shrink-fit tooling systems sized for 3/8 inch shanks.

Key Features

• Micrograin solid carbide construction for high hardness and edge retention
• TiCN coating reduces friction and extends cutting tool life
• 40-degree helix angle supports efficient chip evacuation and smooth cutting action
• Centercutting geometry allows direct plunge milling without pre-drilled entry
• Double-end design provides two cutting ends per tool
• Right-hand cut and right-hand spiral flute for standard CNC and manual mill setups

Compatibility

Designed as an OEM-style replacement and standard fit for milling machines and machining centers accepting a 3/8 inch shank end mill holder or collet.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Always power down and lock out the machine spindle before changing tooling. Seat the shank fully and evenly in the collet or end mill holder to the recommended gauge line before tightening. Verify runout with a dial indicator after installation, as excessive runout will accelerate tool wear and degrade surface finish.
