Accupro 12181630 Square End Mill 1/4 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12181630 is a 2-flute solid carbide square end mill designed for precision milling in a wide range of ferrous and non-ferrous materials. It features a micrograin carbide substrate and a TiCN (titanium carbonitride) coating that increases surface hardness and reduces friction during cutting. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 0.250 inches in diameter with a 0.375-inch length of cut and a 2.000-inch overall length, this is a stub-length tool built for rigidity in tight-clearance machining setups. Licensed machinists and toolroom professionals install and operate this type of end mill in vertical and horizontal milling machines and CNC machining centers.

This end mill is suited for slotting, profiling, and light plunge operations in milling applications where dimensional accuracy is critical. The centercutting geometry allows direct plunge entry without a pre-drilled hole. The right-hand cut and right-hand spiral flute configuration is standard for conventional and climb milling on CNC and manual knee mills. The stub-length classification makes it a preferred choice when minimizing deflection is a priority, particularly in finishing passes or when working with harder workpiece materials.

Key Features

• Solid micrograin carbide construction for wear resistance and edge retention
• TiCN coating reduces friction and extends tool life in ferrous materials
• 40-degree helix angle promotes chip flow and reduces cutting forces
• Centercutting design allows direct plunge milling without pilot drilling
• Stub-length (2.000 inches OAL) body maximizes rigidity and minimizes deflection
• Right-hand cut, right-hand flute spiral geometry for standard milling operations

Compatibility

Designed for use in milling machines and CNC machining centers accepting a 1/4-inch shank; compatible with standard ER collet chucks, end mill holders, and shrink-fit toolholders with a 0.250-inch bore.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the shank fully within the toolholder to the recommended gauge length and verify runout before cutting. Always power down and lock out the spindle before changing tooling. Do not exceed the tool manufacturer's recommended speeds and feeds for the coating type and workpiece material.
