Accupro 12182730 Square End Mill 1/8 in 4-flute Solid Carbide

Product Description

The ACCUPRO 12182730 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. Built from micrograin solid carbide, it delivers the edge retention and rigidity required for tight-tolerance work in hardened steels, cast iron, and exotic alloys. The AlTiN coating adds thermal resistance, making it a strong choice for high-speed dry or semi-dry cutting applications. At 0.125 inches in diameter with a 40-degree helix angle, this stub-length tool is intended for machinists and toolroom operators who need stability and accurate finishes in confined cuts or shallow cavities.

This end mill suits CNC machining centers and manual knee mills where a short, stiff tool is preferred for minimizing deflection. Stub-length geometry keeps the tool close to the holder, improving rigidity during side milling and slotting passes. The centercutting design allows direct plunge entry without a pre-drilled hole. Right-hand cut and right-hand spiral flute configuration is standard for conventional CNC setups.

Key Features

• Solid micrograin carbide construction for superior hardness and wear resistance
• AlTiN finish for high-heat applications and extended tool life in ferrous materials
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting capable - supports direct plunge milling without pre-drilling
• Stub-length (1.5 inches OAL) design minimizes deflection for improved dimensional accuracy
• 4-flute configuration balances material removal rate with surface finish quality

Compatibility

Designed as a standard shank end mill compatible with 1/8 inch collets, end mill holders, and tooling chucks commonly used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully and evenly in the collet or holder to the recommended grip length, and verify runout with a dial indicator before beginning a cut. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.
