Accupro 12178857 Square End Mill 3/4 Inch 2 Flute Carbide

Product Description

The ACCUPRO 12178857 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. It features a 3/4-inch cutting diameter, a 2-inch length of cut, and a 6-inch overall length, making it well-suited for extended-reach profiling and slotting operations. The micrograin carbide construction provides a balance of hardness and toughness. The nACRo finish enhances wear resistance and reduces friction at the cutting edge. Two spiral flutes with a 40-degree helix angle promote efficient chip evacuation and smooth cutting action. This tool is installed and used by machinists and CNC operators in job shop, production, and maintenance machining environments.

This end mill is applied in vertical and horizontal milling operations on machining centers and CNC mills. The centercutting geometry allows plunge entry directly into a workpiece, expanding its use to pocketing and ramping applications. The right-hand cut and right-hand flute configuration is standard for conventional CNC spindle setups. It is appropriate for general-purpose milling of steel, stainless steel, cast iron, and similar materials where a high-helix solid carbide tool is specified.

Key Features

• Solid micrograin carbide construction for extended tool life in demanding cuts
• nACRo coating reduces friction and increases wear resistance at elevated temperatures
• 40-degree helix angle promotes aggressive chip evacuation and reduces cutting forces
• Centercutting design allows direct plunge entry for pocketing and ramping operations
• Right-hand cut, right-hand flute configuration for standard CNC spindle compatibility
• Shank diameter matches cutting diameter at 3/4 inch for straightforward toolholder setup

Compatibility

Designed as a standard-shank solid carbide square end mill compatible with 3/4-inch collet chucks, end mill holders, and shrink-fit toolholders used on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before loading or unloading the tool. Seat the shank fully into the toolholder to the recommended gauge-line depth and secure per the toolholder manufacturer torque specifications. Inspect the cutting edges for chips or coating damage before each use.
