Accupro 12182434 Square End Mill 7/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12182434 is a solid carbide square end mill designed for precision milling operations in metal, composites, and hard materials. It features a 7/64 inch (0.1094 inch decimal) cutting diameter, a 3/8 inch length of cut, and a 1/8 inch shank diameter with an overall length of 1.5 inches. The four-flute, right-hand spiral geometry operates at a 40-degree helix angle, and the TiCN coating adds surface hardness and lubricity to extend tool life in abrasive materials. Micrograin carbide substrate supports edge integrity at higher feed rates. Installed by machinists and tool-and-die professionals on CNC mills and manual milling machines.

This end mill is suited for slotting, profiling, and plunge cuts in ferrous and non-ferrous materials where tight tolerances are required. The centercutting design allows direct plunge entry without a pre-drilled hole. The regular-length geometry fits standard toolholders and collet chucks taking a 1/8 inch shank. Typical applications include mold work, fixture fabrication, and precision part machining where a small-diameter four-flute carbide tool is specified.

Key Features

• Solid micrograin carbide construction for edge sharpness and wear resistance
• TiCN finish for increased surface hardness and reduced friction in abrasive cuts
• 40-degree helix angle promotes efficient chip evacuation and smoother finish
• Centercutting capability allows direct plunge milling without pre-drilling
• Right-hand cut and right-hand flute for standard spindle operation
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit and finish

Compatibility

Designed for use in CNC and manual milling machines accepting a 1/8 inch shank collet or toolholder. Fits standard ER and precision collet systems sized for 1/8 inch shanks.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and the spindle locked. Ensure the collet or toolholder is clean and free of debris before seating the shank. Verify shank runout with a dial indicator after clamping to confirm concentricity. Follow the machine and toolholder manufacturer torque guidelines when securing the collet nut.
