Accupro 12182198 Square End Mill 11/16 in 3 Flute Carbide

Product Description

The ACCUPRO 12182198 is a solid carbide square end mill designed for high-performance milling operations in ferrous and nonferrous metals. It features an 11/16 inch (0.6875 inch) cutting diameter, a 1 inch length of cut, and a 3/4 inch shank diameter with an overall length of 3 inches. The micrograin carbide substrate delivers hardness and edge retention, while the AlTiN coating improves heat resistance at elevated cutting speeds. With 3 spiral flutes and a 40-degree helix angle, it promotes efficient chip evacuation and smooth cutting action. This tool is used by machinists and tool-and-die professionals running vertical or horizontal milling machines and CNC machining centers.

This end mill is suited for profiling, slotting, and peripheral milling in steel, stainless, cast iron, and similar workpiece materials. The centercutting geometry allows plunge entry directly into the material, which expands its usefulness in pocketing operations. The stub length category keeps the overhang short, improving rigidity and reducing chatter during aggressive cuts. Right-hand cut and right-hand flute configuration is standard for conventional spindle-forward milling setups.

Key Features

• 11/16 inch cutting diameter with a mill diameter tolerance of plus 0.000 and minus 0.002 inches
• Solid carbide micrograin substrate for edge hardness and wear resistance
• AlTiN finish for elevated heat resistance in high-speed ferrous machining
• 40-degree helix angle with 3 spiral flutes for efficient chip evacuation
• Centercutting design allows direct plunge entry for pocketing operations
• Stub length construction reduces overhang and improves rigidity
• Right-hand cut and right-hand flute for standard spindle-forward use

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual milling machines accepting a 3/4 inch straight shank end mill holder or collet.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Secure the 3/4 inch shank in a clean, properly sized collet or end mill holder and torque the retention mechanism to the spindle manufacturer's specification. Inspect the shank and holder bore for chips or debris before seating the tool. Confirm spindle direction is set to right-hand rotation before engaging the cut.
