Accupro 12181764 Square End Mill 9/16 in 2 Flute Carbide

Product Description

The ACCUPRO 12181764 is a solid carbide square end mill designed for precision milling in metal, composite, and hard material applications. Built from micrograin carbide, it delivers the rigidity and edge retention required for demanding cuts. The 2-flute configuration with a 40-degree spiral helix promotes efficient chip evacuation and smooth cutting action. At 6 inches overall length with a 3-inch length of cut, this is an extra-long reach tool suited for deep-pocket and stepped-feature work. Centercutting geometry allows direct plunge entry without a pre-drilled hole. This tool is installed and operated by machinists and CNC programmers working on mills and machining centers.

This end mill is intended for use in both manual and CNC milling operations where extended reach is required. The extra-long body makes it well suited for deep cavity work, side-wall finishing, and applications where standard-length tools cannot reach the workpiece feature. The right-hand cut and right-hand flute spiral are compatible with conventional and climb milling strategies. Uncoated micrograin carbide construction is appropriate for dry cutting or use with cutting fluid in ferrous and non-ferrous materials where a coating-specific chemistry is not required.

Key Features

• Micrograin solid carbide construction for edge retention and rigidity in demanding cuts
• 40-degree helix angle promotes aggressive chip evacuation and smooth surface finish
• Centercutting design allows direct plunge milling without a pilot hole
• Extra-long 6-inch OAL with 3-inch LOC for deep-pocket and extended-reach applications
• Right-hand cut and right-hand spiral flute compatible with standard milling spindle rotation
• 2-flute geometry balances chip clearance and tool strength for slotting and profiling

Compatibility

Designed as a direct-fit tooling selection for milling machines and machining centers accepting a 9/16-inch straight shank in a collet, end mill holder, or equivalent toolholding system.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully powered down and at rest before mounting or removing the tool. Seat the shank fully into the toolholder to the recommended engagement depth before tightening to prevent runout and pull-out during operation. Verify shank diameter tolerance stack-up against the toolholder bore specification before use.
