Helical Solutions 82480 Square End Mill 3/8 in 3 Flute Carbide

Product Description

The HELICAL SOLUTIONS 82480 is a 3-flute square end mill designed for high-performance aluminum milling. Built from solid carbide, it features a 40-degree helix angle and a variable index (unequal flute spacing) to reduce chatter and improve surface finish at aggressive feed rates. The Zplus coating provides lubricity and edge hardness suited for non-ferrous materials. With a reduced neck profile and extended reach of 3.125 inches, it handles deep-pocket and slotting operations where clearance is critical. Machinists and CNC operators use this tool in production and job-shop environments on vertical machining centers and CNC mills.

This end mill is engineered specifically for aluminum and other non-ferrous alloys. The reduced neck geometry allows access to deep cavities without sacrificing rigidity along the fluted cutting zone. The 1/2-inch length of cut handles standard slotting and profiling passes, while the 6-inch overall length accommodates setups with extended tool-holder projection. It is well suited for aerospace, automotive, and general machining applications where aluminum stock removal and finish quality are priorities.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous milling
• 40-degree helix angle promotes efficient chip evacuation in aluminum
• Variable index flute spacing reduces harmonic vibration and chatter
• Zplus coating enhances lubricity and extends tool life on aluminum
• Reduced neck design enables deep-pocket reach up to 3.125 inches
• Right-hand cut, right-hand flute, centercutting — supports plunge entry

Compatibility

Designed for use with standard straight-shank tool holders accepting a 3/8-inch shank diameter. Optimized for aluminum and non-ferrous alloy machining in CNC milling applications.

Installation Notes

Install in a clean, properly sized collet or end mill holder to the recommended gauge-length specification for the setup. Ensure the machine spindle is fully stopped and the tool-holder is securely torqued before running. Verify runout with a dial indicator after tool change, particularly when using the reduced neck length for deep-reach operations. Follow the tool manufacturer cutting data recommendations for spindle speed and feed rate when transitioning to a new tool or coating type.
