Accupro 12181525 Square End Mill 11/16 in 2 Flute Carbide

Product Description

The ACCUPRO 12181525 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. It features an 11/16 inch (0.6875 inch) mill diameter, a 1-1/2 inch length of cut, and a 40-degree helix angle that promotes efficient chip evacuation and reduces cutting forces. The TiCN (Titanium Carbonitride) coating increases surface hardness and wear resistance, extending tool life in ferrous and non-ferrous applications. This is a single-end, right-hand cutting, right-hand flute tool manufactured from micrograin solid carbide. It is installed and operated by machinists and CNC tool room technicians.

This end mill is suited for slot milling, peripheral milling, and profiling operations on machining centers and manual knee mills. The 3/4 inch shank diameter fits standard ER collet chucks, end mill holders, and shrink-fit toolholders common in production and job shop environments. The regular length profile and centercutting geometry allow both plunge and ramp entry cuts. It is appropriate for use on ferrous metals, stainless steel, and high-temperature alloys where TiCN coating provides a thermal and abrasion advantage over uncoated carbide.

Key Features

• 11/16 inch mill diameter with a tolerance of +0.000 / -0.002 inches for consistent fit and finish
• TiCN coating for improved wear resistance and extended tool life in demanding materials
• 40-degree helix angle promotes smooth cutting action and efficient chip evacuation
• Centercutting design enables plunge milling and ramp entry without a pre-drilled hole
• Micrograin solid carbide construction provides rigidity and edge retention
• Right-hand cut, right-hand spiral flute — compatible with standard CNC spindle rotation

Compatibility

Designed as a standard square end mill for use in CNC machining centers and manual mills accepting a 3/4 inch shank diameter via ER collet chucks, end mill holders, or shrink-fit tooling systems.

Installation Notes

Install and torque the toolholder to the spindle according to the machine tool manufacturer specifications before engaging the workpiece. Ensure the shank is fully seated in the holder to the minimum engagement depth recommended for the holder type. Power down and lock out the spindle before changing or inspecting tooling. Do not exceed the end mill diameter or depth-of-cut parameters established during the machining process setup.
