Accupro 72011976 Square End Mill 3/8 in 6 Flute Carbide

Product Description

The ACCUPRO 72011976 is a solid carbide square end mill designed for high-performance milling in demanding materials, particularly high-temperature alloys. With a 3/8 inch (0.3750 inch) mill diameter and six flutes, it delivers smooth cutting action and efficient chip evacuation in difficult-to-machine workpiece materials. The AlTiN+ coating provides thermal resistance and extended tool life under the elevated cutting temperatures common when machining aerospace-grade and heat-resistant alloys. Variable helix and variable index geometry reduce chatter and vibration, improving surface finish and dimensional accuracy. This tool is intended for use by machinists and CNC operators working in precision manufacturing environments.

This end mill is suited for milling operations on high-temp alloys (material code S), including nickel-based superalloys and similar difficult-to-machine materials commonly found in aerospace, medical, and energy applications. It is a single-end tool with a 1/2 inch length of cut, a 3/8 inch shank diameter, and a 2.0 inch overall length. Right-hand cutting and right-hand flute direction are standard for conventional CNC machining center setups. Center-cutting capability allows for plunge entry. No coolant-through feature is present, so external coolant or air blast is recommended when required by the application.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN+ coating for high-temperature performance and extended tool life
• Variable helix (36-40 degrees) and variable index geometry reduce vibration and chatter
• Six helical flutes for efficient chip evacuation and smooth surface finish
• Center-cutting design allows direct plunge entry without pre-drilling
• Single-end configuration with 3/8 inch shank for standard collet or end mill holder fitment

Compatibility

Designed for use in CNC machining centers and manual mills with standard 3/8 inch collet chucks or end mill holders. Primary workpiece material is high-temperature alloy (material code S). No specific machine model compatibility was provided by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before loading or removing the end mill from the tool holder. Use a properly sized collet or end mill holder rated for 3/8 inch shank tooling and torque the retention mechanism per the tool holder manufacturer specification. Verify runout at the tool tip before beginning the cut, as excessive runout accelerates wear and can damage the workpiece or tool.
