Accupro 12182055 Square End Mill 15/32 Inch 3 Flute Carbide

Product Description

The ACCUPRO 12182055 is a solid carbide square end mill designed for precision milling operations in metal, composites, and engineering plastics. With a 15/32 inch (0.4688 inch) milling diameter, a 40-degree helix angle, and a 3-flute spiral flute geometry, this tool delivers efficient chip evacuation and a clean finish on a wide range of workpiece materials. The micrograin carbide construction provides the hardness and wear resistance required for demanding cutting applications. It is a centercutting, right-hand cut, right-hand flute tool suited for use on vertical machining centers, CNC mills, and manual knee mills.

This end mill fits standard 1/2 inch toolholders and collet chucks, making it compatible with common shop setups in job shops, toolrooms, and production environments. With a 1 inch length of cut and a 3 inch overall length, it is classified as a regular-length tool, appropriate for general-purpose slotting, profiling, and peripheral milling at moderate depths. It is well-suited for machinists and toolmakers performing prototype work, repair machining, or short-run production. The uncoated finish makes it easy to re-sharpen when dulling occurs.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• 40-degree helix angle promotes smooth cutting action and efficient chip flow
• Centercutting design allows direct plunge entry into the workpiece
• 3 spiral flutes balance cutting speed and chip clearance
• Right-hand cut and right-hand flute configuration for standard spindle direction
• Uncoated finish simplifies resharpening and suits a broad range of materials

Compatibility

Designed for use in 1/2 inch collet chucks, end mill holders, and shrink-fit toolholders on CNC and manual milling machines. No specific OEM machine model compatibility was provided by the manufacturer for this part number.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is in an energy-isolated state before changing tooling. Insert the shank to the full recommended engagement depth in the toolholder to avoid runout and tool pullout during cutting. Follow machine manufacturer torque specifications for set screws or collet nuts, and verify runout with a dial indicator before beginning the cut.
