Accupro 12183531 Square End Mill 3/8 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12183531 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. The tool measures 0.375 inches in diameter with a 1-inch length of cut and a 4-inch overall length. Four spiral flutes with a 40-degree helix angle promote efficient chip evacuation and smooth cutting action. A TiCN (titanium carbonitride) coating increases surface hardness and wear resistance compared to uncoated carbide. The micrograin carbide substrate supports edge sharpness at higher feed rates. This is a right-hand cut, right-hand flute, centercutting tool, meaning it can plunge directly into material. Licensed machinists, tool-and-die makers, and CNC operators are the typical end users.

This end mill suits long-reach milling applications in job shops, production machining, and maintenance environments. The long length type and 1-inch length of cut make it appropriate for slot milling, profiling, and pocket work where a standard-length tool cannot reach the floor of a deep feature. The 3/8-inch shank diameter fits standard collets and end mill holders common to vertical machining centers and manual knee mills. Applications include side milling, full-slot cutting, and plunge entry without a pre-drilled hole.

Key Features

• Solid micrograin carbide construction for edge retention in demanding cuts
• TiCN coating improves wear resistance and reduces built-up edge on the cutting face
• 40-degree helix angle promotes aggressive chip lift and reduced cutting forces
• Centercutting geometry allows direct plunge entry without a pilot hole
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• Long length type with 1-inch LOC provides access to deeper features

Compatibility

Designed for use in standard 3/8-inch collets, end mill holders, and shrink-fit tooling on vertical machining centers and manual mills. No specific machine model compatibility was provided by the manufacturer for this part number.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and lock out the spindle drive before loading or removing the tool from its holder. Seat the shank fully into the collet or holder to the recommended grip length before torquing the retention nut. Verify runout with a dial indicator after installation and before starting the cut, as runout directly affects tool life and surface finish on carbide end mills.
