Accupro 12181730 Square End Mill 7/16 in 2 Flute Altin Carbide

Product Description

The ACCUPRO 12181730 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous metals. It features a 7/16 inch cutting diameter, a 2 inch length of cut, and a 4 inch overall length with a matching 7/16 inch shank diameter. The AlTiN coating provides heat and oxidation resistance at elevated cutting temperatures, extending tool life in demanding applications. The 40-degree helix angle and spiral flute geometry promote efficient chip evacuation. Micrograin carbide construction delivers the hardness and edge retention required for high-speed metal removal. Licensed machinists and CNC operators are the primary installers and users of this tooling.

This end mill is suited for slotting, profiling, and peripheral milling in a variety of materials including alloy steels, stainless steels, and hardened workpieces. Its long-length classification makes it appropriate for reaching deeper pockets and features where standard-length end mills fall short. The centercutting design allows plunge entry directly into the workpiece. Right-hand cut and right-hand flute configuration is standard for conventional CNC machining centers and manual knee mills.

Key Features

• Solid micrograin carbide construction for hardness and edge stability
• AlTiN coating for high-temperature wear resistance
• 40-degree helix angle with spiral flute for efficient chip evacuation
• Centercutting geometry allows direct plunge milling
• Long-length classification at 2 inch length of cut for deep-reach applications
• Right-hand cut and right-hand flute for standard CNC and manual mill spindles

Compatibility

Designed as a direct-fit tooling solution for standard 7/16 inch collets, end mill holders, and shrink-fit toolholders used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully within the holder to the recommended engagement depth and torque the set screw or collet nut to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning cuts to protect both the tool and the workpiece.
