Helical Solutions 49286 Ball End Mill 0.5in 3 Flute Carbide

Product Description

The HELICAL SOLUTIONS 49286 is a 3-flute solid carbide ball end mill designed for high-performance milling of aluminum alloys and non-ferrous materials. It features a 0.5-inch mill diameter, a 1.25-inch length of cut, and a 40-degree high-helix angle that promotes efficient chip evacuation in gummy, ductile materials. The Zplus PVD coating reduces built-up edge and extends tool life in aluminum and other non-ferrous applications. With a 0.25-inch nose radius and right-hand cutting and flute direction, this tool is suited for both roughing and finishing passes in a single setup.

This end mill is built for CNC machining centers and manual mills running aluminum alloys, copper, brass, and other non-ferrous metals. The standard-length, straight-cylindrical shank fits common 0.5-inch toolholders and collet systems. It is a single-end tool, making it appropriate for high-speed profiling, slotting, and 3D contouring operations where surface finish and material removal rate both matter. The variable-pitch geometry helps reduce harmonic chatter during aggressive cuts.

Key Features

• 40-degree high-helix angle promotes chip evacuation in aluminum and ductile materials
• Zplus PVD coating reduces built-up edge and extends tool life
• 3-flute variable-pitch geometry reduces chatter during roughing and finishing
• Ball nose profile with 0.25-inch nose radius enables 3D contouring and profiling
• Right-hand cut and right-hand flute direction; compatible with standard CNC toolholding

Compatibility

Designed for use in aluminum alloys and non-ferrous metals (Primary Workpiece Material Code: N). Fits standard 0.5-inch collets and toolholders with a straight-cylindrical shank. Part of the HELICAL SOLUTIONS 3 Flute, Ball - 40 Helix, Variable Pitch, End Mills for Aluminum Alloys and Non-Ferrous Materials series.

Installation Notes

Installation and operation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the toolholder to the recommended gauge-line depth before tightening. Verify runout does not exceed the maximum TIR of 0.0003 inches after seating. Follow machine manufacturer guidelines for spindle speed, feed rate, and depth of cut appropriate to the workpiece material and machine rigidity.
