Helical Solutions 82604 Square End Mill 1/2 in 6 Flute Carbide

Product Description

The HELICAL SOLUTIONS 82604 is a 6-flute, single-end square end mill ground from solid carbide and finished with an APLUS coating for high-performance milling in ferrous and hard materials. The tool measures 0.5 inches in cutting diameter with a 0.625-inch length of cut, a 2.25-inch reach length, and a 4-inch overall length. The variable-index flute geometry reduces harmonic chatter during aggressive cuts, making it well-suited for roughing and finishing passes in steel, stainless steel, cast iron, and high-temperature alloys. Right-hand cutting and right-hand helical flutes are standard. Helix angle is 37 degrees.

This end mill is designed for CNC machining centers and manual mills where close-tolerance work in hard or abrasive materials demands a carbide substrate with a wear-resistant coating. The reduced-neck profile extends reach beyond the shank without sacrificing rigidity, allowing access to deeper pockets and stepped features. Typical applications include mold work, aerospace component machining, and general production runs in steel and stainless steel. The straight 0.5-inch shank fits standard collets and end mill holders without adapters.

Key Features

• Solid carbide substrate for rigidity and wear resistance in ferrous materials
• APLUS coating extends tool life in steel, stainless steel, cast iron, and high-temperature alloys
• Variable-index flute spacing reduces chatter and improves surface finish
• Reduced-neck geometry provides 2.25 inches of reach for deep-pocket access
• 37-degree helix angle promotes efficient chip evacuation in right-hand cut direction
• Center-cutting capable; suitable for plunge entry

Compatibility

Designed for use in steel, stainless steel, cast iron, and high-temperature alloy applications (material codes P, M, K, S). Fits any standard 1/2-inch collet or end mill holder.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power isolated per shop lockout procedures. Verify collet runout before use, as excessive runout accelerates wear on a variable-index tool. Confirm cutting parameters are appropriate for the workpiece material and machine spindle power before engaging the cut. Do not use coolant-through circuits with this tool as it is not rated for coolant-through delivery.
