Accupro 12182235 Square End Mill 1/8 in 3 Flute Carbide

Product Description

The ACCUPRO 12182235 is a solid carbide square end mill designed for precision milling operations across a wide range of materials. With a 0.125-inch mill diameter, a 1-inch length of cut, and a 3-inch overall length, this tool is built for tight-tolerance work where consistency matters. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Constructed from micrograin solid carbide, it delivers the hardness and edge retention required for demanding production environments. This is a centercutting, single-end tool with a right-hand cut and right-hand flute spiral configuration, suitable for plunge, slot, and profile milling.

This end mill is intended for use in CNC machining centers, manual mills, and toolroom applications where small-diameter, high-precision cutting is required. The extra-long length classification and 3-flute geometry make it suitable for reaching into deeper pockets and cavities while maintaining surface finish quality. It is sized for use in standard 1/8-inch collets or ER collet chucks. This tool is commonly installed and operated by machinists and toolroom professionals in aerospace, automotive, medical device, and general metalworking applications.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• 40-degree helix angle for efficient chip evacuation during milling
• Centercutting design allows direct plunge entry into workpieces
• Right-hand cut and right-hand spiral flute configuration
• Uncoated finish suitable for use with cutting fluids on ferrous and non-ferrous materials
• Mill diameter tolerance of +0.000/-0.002 inches for precise fitment and repeatable results

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 1/8-inch collet systems on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the collet or chuck. Use a torque wrench calibrated to the toolholder manufacturer specification when tightening collet nuts — do not overtighten. Inspect the cutting edges for chipping or wear before each use and replace if edge integrity is compromised.
