Accupro 72012933 Square End Mill 1/2 Inch 6 Flute Carbide

Product Description

The ACCUPRO 72012933 is a single-end, solid carbide square end mill designed for high-performance milling in demanding materials. With a 0.5000-inch mill diameter, 6 flutes, and a variable helix angle of 36 to 40 degrees, this tool is built to reduce chatter and improve surface finish in difficult-to-machine workpieces. The AlTiN+ coating provides thermal resistance and extended tool life. It is center-cutting, right-hand cutting, and right-hand flute, making it suitable for plunge entry, slotting, and peripheral milling operations. Machinists and tool-and-die professionals working with high-temperature alloys will find this end mill well matched to the demands of production milling.

This end mill is primarily intended for high-temp alloy workpiece materials, classified under material code S. Typical applications include aerospace and power-generation component machining where nickel-based superalloys, titanium, and similar hard materials are common. The variable helix and variable index geometry help manage cutting forces and minimize vibration in these challenging applications. It fits standard 1/2-inch collets and toolholders commonly found on CNC machining centers and manual knee mills.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN+ coating for elevated thermal protection and extended tool life
• Variable helix (36-40 degrees) and variable index geometry reduce chatter and improve finish
• Center-cutting design allows direct plunge entry without pre-drilling
• 6-flute configuration increases feed rate potential and improves surface finish
• Right-hand cut and right-hand helix for standard CNC and manual mill setups

Compatibility

Designed for use in standard 1/2-inch collets and toolholders. Optimized for high-temp alloy workpiece materials (material code S), including nickel-based superalloys and titanium, in CNC and manual milling applications.

Installation Notes

Installation is performed by qualified machinists using appropriate collet chucks or end mill holders torqued per toolholder manufacturer specifications. Ensure the machine spindle is fully stopped and de-energized before changing tooling. Confirm runout with a dial indicator before committing to a production cut. Follow your shop's speeds-and-feeds guidelines for the specific workpiece material and coating type.
