Accupro 12182288 Square End Mill 7/16 in 3 Flute Carbide

Product Description

The ACCUPRO 12182288 is a solid carbide square end mill designed for precision metal removal in demanding machining applications. It features a 7/16 inch cutting diameter, a 1 inch length of cut, and a 4 inch overall length, making it well suited for slots, pockets, and peripheral milling operations. The micrograin carbide construction provides hardness and wear resistance at elevated cutting speeds. An AlTiN coating reduces friction and extends tool life when cutting ferrous and hardened materials. This end mill is intended for use by machinists and tool-and-die professionals operating CNC mills and manual knee mills.

This is a long-series, single-end square end mill with a 40-degree helix angle and spiral flute geometry. The centercutting design allows plunge entry directly into a workpiece. Right-hand cut and right-hand flute orientation are standard for conventional CNC spindle direction. Typical applications include slotting and profiling in steel, stainless steel, cast iron, and similar ferrous materials. The 7/16 inch shank diameter matches the cutting diameter for direct collet or end mill holder mounting without a reduction sleeve.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• AlTiN finish for heat resistance and extended tool life in ferrous materials
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting geometry allows direct plunge milling without a pilot hole
• 3-flute configuration balances chip room and cutting edge count for medium-to-finish passes
• Mill diameter tolerance of plus 0.000 / minus 0.002 inches for predictable dimensional accuracy

Compatibility

Designed as an OEM-style tooling option for CNC machining centers and manual mills accepting a 7/16 inch straight shank via collet, end mill holder, or shrink-fit toolholder.

Installation Notes

Installation is performed by qualified machinists familiar with rotating cutting tool safety. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before loading or removing the tool. Seat the shank fully into the collet or holder to the recommended grip length and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial indicator before initiating a cut, as excessive runout will accelerate edge wear and reduce dimensional accuracy.
