Helical Solutions 84412 Ball End Mill 3/16 in 6 Flute Carbide

Product Description

The HELICAL SOLUTIONS 84412 is a 6-flute solid carbide ball end mill designed for high-performance milling in demanding metal removal applications. With a 3/16-inch cutting diameter and a 9/16-inch length of cut, this single-end mill carries a variable index geometry that reduces harmonic vibration during both roughing and finishing passes. The APLUS PVD coating improves heat resistance and surface hardness, extending tool life in abrasive materials. Overall length is 2.5 inches with a 3/16-inch straight-cylindrical shank. A 37-degree helix angle promotes efficient chip evacuation and reduces cutting forces across a range of workpiece materials.

This end mill is engineered for milling steel, stainless steel, cast iron, high-temperature alloys, and tool steels. It is suited to CNC machining centers running tight-tolerance contour work, profiling, and slotting operations where both material removal rate and surface finish quality are priorities. The ball nose geometry makes it particularly effective for 3D contouring and complex curved surfaces on ferrous and nickel-based workpiece materials.

Key Features

• 6-flute variable index design reduces chatter and harmonic vibration during aggressive cuts
• APLUS PVD coating provides elevated thermal resistance and wear protection for extended tool life in hard steels and high-temp alloys
• 37-degree right-hand helix angle promotes efficient chip flow and reduces cutting forces
• Centercutting geometry allows direct plunge entry into the workpiece
• Solid carbide construction delivers rigidity and dimensional stability in tight-tolerance applications
• Ball nose profile supports 3D contour milling, profiling, and finishing of curved surfaces

Compatibility

The 84412 belongs to the HELICAL SOLUTIONS HEV-6 series and is rated for steel, stainless steel, cast iron, and high-temperature alloys (ISO material codes P, M, K, S). Secondary compatibility includes general steel applications.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Seat the 3/16-inch straight shank fully and squarely in a precision collet or end mill holder rated for the shank diameter before tightening. Verify TIR does not exceed 0.0005 inches at the cutting edge after clamping. Set appropriate spindle speed and feed rate for the workpiece material and depth of cut per the machine tool manufacturer and tooling data sheets before beginning the operation.
