Accupro 12183844 Square End Mill 3/4 in 5 Flute Carbide

Product Description

The ACCUPRO 12183844 is a solid carbide square end mill designed for high-performance milling in ferrous and non-ferrous materials. It features a 3/4 inch cutting diameter, a 3-1/4 inch length of cut, and a 6 inch overall length with a matching 3/4 inch shank. The five-flute geometry with a 45-degree helix angle promotes aggressive material removal while maintaining surface finish. An AlTiN coating provides heat resistance and extended tool life in dry or semi-dry cutting conditions. This is a centercutting tool, allowing direct plunge entry without a pre-drilled starting hole. Licensed machinists and CNC operators install this tool in vertical or horizontal machining centers.

This end mill suits production and job-shop environments running steel, stainless steel, cast iron, and similar hard materials. The spiral flute design with right-hand cut and right-hand flute direction is the standard configuration for conventional and climb milling on CNC machining centers. The regular-length body and non-extended reach geometry make it well suited for general-purpose pocketing, profiling, and slotting operations where rigidity is a priority. It is sold as a single-piece unit with a minimum order quantity of one.

Key Features

• Solid carbide micrograin substrate for rigidity and wear resistance
• AlTiN coating for thermal protection in high-speed and dry machining
• 45-degree helix angle improves chip evacuation and reduces cutting forces
• Five flutes provide higher feed rates compared to standard four-flute geometry
• Centercutting design allows direct plunge milling without pilot drilling
• Right-hand cut and right-hand spiral flute for standard CNC spindle use

Compatibility

Designed as a standard 3/4 inch shank end mill compatible with ER collets, milling chucks, and shrink-fit holders sized for 3/4 inch straight shanks on CNC vertical and horizontal machining centers.

Installation Notes

Installation is performed by licensed machinists or CNC operators. Confirm the holder bore and collet size match the 3/4 inch shank before mounting. Verify spindle rotation direction is right-hand before engaging the cut. Follow the machine tool manufacturer runout and clamping torque guidelines for the toolholder type in use.
