Accupro 12181781 Square End Mill 7/32 in 2 Flute Carbide

Product Description

The ACCUPRO 12181781 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin carbide with an AlTiN (aluminum titanium nitride) finish, this tool delivers high wear resistance and thermal stability in demanding cutting environments. It features a 7/32 inch (0.2188 inch) cutting diameter, a 1 inch length of cut, and a 3 inch overall length. The 40-degree helix angle promotes efficient chip evacuation, while the 2-flute, right-hand spiral configuration supports both slotting and peripheral milling. CNC machinists and tool-and-die professionals are the primary users of this end mill.

This end mill is suited for milling ferrous and non-ferrous metals, hardened steels, and alloy materials where an AlTiN coating extends tool life compared to uncoated carbide. The extra-long length type provides added reach for deeper pockets or features that standard-length tools cannot access. The 1/4 inch shank diameter fits standard collets and tool holders commonly found in CNC machining centers and manual mills. The centercutting design allows plunge milling directly into workpiece material without pre-drilling.

Key Features

• AlTiN finish for high-heat and wear resistance in ferrous and hardened material cutting
• 40-degree helix angle for aggressive chip evacuation and smooth cutting action
• Centercutting capability allows direct plunge entry into the workpiece
• Micrograin solid carbide construction for rigidity and edge retention
• Right-hand cut and right-hand flute spiral for standard CNC spindle compatibility
• Extra-long length type provides reach for deep-pocket milling operations

Compatibility

Designed as a direct-fit replacement or standard tooling choice for 1/4 inch shank collets and tool holders used in CNC machining centers, manual knee mills, and similar milling equipment.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Always power down and lock out the machine spindle before loading or changing tooling. Seat the shank fully into the collet or tool holder and torque the retention mechanism to the machine manufacturer's specification. Verify runout with a dial indicator before beginning a production cut.
