Accupro 12185050 Square End Mill 0.5 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12185050 is a double-end, solid carbide square end mill designed for high-performance milling operations in metal, composites, and engineered plastics. It features a 0.5-inch mill diameter, a 1-inch length of cut, and a 40-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The micrograin carbide substrate delivers edge retention and rigidity suited for demanding material removal at elevated feeds and speeds. Machinists and CNC operators use this tool in vertical mills, machining centers, and multi-axis setups where dimensional accuracy and tool life are critical.

This end mill is appropriate for general-purpose profiling, slotting, and contouring in job-shop and production environments. The double-end configuration extends tool value by providing a second usable cutting end. The bright uncoated finish makes it compatible with a wide range of cutting fluids and base materials where coating interaction is a concern. Right-hand cut and right-hand spiral flute direction are standard for most CNC and manual milling applications.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• 40-degree helix angle promotes efficient chip flow and reduced cutting forces
• Double-end design provides two cutting ends per tool, extending usable life
• Centercutting geometry allows plunge and ramp entry cuts
• Right-hand cut with right-hand spiral flute for standard CNC compatibility
• Bright uncoated finish suitable for use with most cutting fluids and work materials

Compatibility

Designed as a direct-fit replacement or standard tooling selection for 0.5-inch shank ER collet chucks, end mill holders, and shrink-fit toolholders used in CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the 0.5-inch shank to the minimum recommended engagement depth in the toolholder to maintain runout tolerance. Verify shank diameter tolerance compatibility with the holder specification before tightening to prevent tool pullout during high-feed passes.
