Accupro 12183450 Square End Mill 3/16 in 4 Flute Carbide

Product Description

The ACCUPRO 12183450 is a solid carbide square end mill designed for precision milling operations in metal, composites, and hard plastics. Built from micrograin carbide, it offers a 3/16 inch cutting diameter with a 1 inch length of cut and a 4 inch overall length, making it a long-series tool suited for deeper reach applications. The 4-flute, spiral geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. The centercutting design allows direct plunge entry without a pilot hole. This tool is installed and operated by machinists and tool-and-die professionals using CNC mills and manual knee mills.

This end mill is suited for slotting, profiling, and contouring operations in ferrous and non-ferrous materials where a long-reach tool is required. The uncoated micrograin carbide construction works well in applications where coolant is used or where coating compatibility with the workpiece material is a concern. The 3/16 inch shank diameter matches the cutting diameter, keeping the setup straightforward for standard collets and end mill holders. Right-hand cut and right-hand flute orientation are standard for conventional CNC and manual milling machine spindles.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• 4-flute spiral geometry with 40-degree helix for efficient chip flow
• Centercutting capable — supports direct plunge milling
• Long-series length with 1 inch length of cut and 4 inch overall length
• Uncoated finish suitable for use with cutting fluids
• Right-hand cut, right-hand flute — compatible with standard spindle rotation

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 3/16 inch collets and end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully in the collet or holder and torque the retention hardware to the machine manufacturer specification. Verify runout with a dial indicator before beginning a production cut.
