Accupro 12181728 Square End Mill 7/16 in 2 Flute Carbide

Product Description

The ACCUPRO 12181728 is a solid carbide square end mill designed for precise material removal in milling applications. Built from micrograin carbide, it delivers the hardness and edge retention needed for consistent performance in ferrous and non-ferrous materials. The 7/16 inch cutting diameter pairs with a 40-degree helix angle and spiral flute geometry to promote efficient chip evacuation and reduce cutting forces. With two flutes and a long-length configuration, this end mill suits operations requiring extended reach into deep pockets or slots. It is a centercutting tool, meaning it can plunge directly into workpiece material. Right-hand cut and right-hand flute orientation are standard for conventional milling setups.

This end mill is suited for use in CNC machining centers, manual knee mills, and similar setups found in job shops, tool rooms, and production environments. The long overall length of 4 inches and 2-inch length of cut make it appropriate for slotting, profiling, and pocketing operations where standard-length tools cannot reach. Machinists and CNC operators working with aluminum, steel, brass, and similar materials will find this geometry well-matched to general-purpose cutting tasks. The uncoated finish keeps regrinding straightforward.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• 40-degree helix angle promotes efficient chip evacuation in deep-cut applications
• Centercutting design allows direct plunge entry into workpiece material
• Long-length configuration with 2 inch length of cut and 4 inch overall length for extended reach
• Right-hand cut and right-hand flute orientation for standard milling setups
• Uncoated finish simplifies regrinding and reconditioning

Compatibility

Designed as a general-purpose replacement or production end mill for standard 7/16 inch collets, ER collet chucks, and end mill holders used in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the holder and torque the collet or set screw to the tool holder specification. Verify runout with a dial indicator before beginning a cut to confirm proper seating and minimize tool deflection.
