Helical Solutions 49406 Ball End Mill 3/4 in 3 Flute Carbide

Product Description

The HELICAL SOLUTIONS 49406 is a solid carbide ball end mill designed for material removal in aluminum alloys and non-ferrous metals. It features a 3/4 inch cutting diameter, a 1-5/8 inch length of cut, and a 4 inch overall length with a matching 3/4 inch straight cylindrical shank. The 40-degree high helix geometry promotes efficient chip evacuation in gummy non-ferrous materials, while the three-flute variable pitch design reduces harmonic chatter during both roughing and finishing passes. A Zplus PVD coating adds surface hardness and lubricity without the thickness that can close tight tolerances. This is a single-end tool ground to h6 shank and diameter tolerances with a maximum TIR of 0.0003 inches.

This end mill is suited for CNC machining centers running aluminum, brass, copper, and other non-ferrous workpiece materials. Its standard-length profile fits most vertical and horizontal milling setups where reach is not a limiting factor. The ball nose geometry makes it the right choice for 3D contouring, ramping, and floor finishing operations in non-ferrous programs. It covers both roughing and finishing material removal types in a single tool, reducing tool changes in production runs.

Key Features

• 3/4 inch ball nose diameter with 0.3750 inch nose radius for accurate 3D contour work
• 40-degree high helix angle promotes fast chip evacuation in aluminum and non-ferrous materials
• Three-flute variable pitch design reduces chatter and improves surface finish
• Zplus PVD coating adds wear resistance and lubricity for extended tool life in non-ferrous cuts
• Solid carbide construction with h6 diameter and shank tolerances and 0.0003 inch maximum TIR
• Single-end, right-hand cut and flute direction; straight cylindrical shank for standard collet or end mill holder use

Compatibility

Designed for use in CNC milling applications targeting aluminum alloys and non-ferrous metals. The 3/4 inch straight cylindrical shank is compatible with standard ER, TG, and shrink-fit toolholders sized for 3/4 inch shank end mills.

Installation Notes

Installation and tool changes must be performed with the machine spindle at a full stop and all motion controls disabled per shop lockout procedures. Seat the shank fully in the toolholder and torque the retention mechanism to the toolholder specification before spindle engagement. Verify runout at the cutting edge with a dial indicator before starting the program, especially given the 0.0003 inch TIR spec on this tool. Coolant-through is not supported; direct external coolant or air blast at the cutting zone to assist chip clearance.
