Helical Solutions 47196 Ball End Mill 3/8 in 3 Flute Carbide

Product Description

The HELICAL SOLUTIONS 47196 is a 3-flute solid carbide ball end mill designed for high-performance milling of aluminum alloys and non-ferrous materials. With a 3/8 inch cutting diameter, a 40-degree high-helix angle, and a Zplus PVD coating, this single-end tool delivers efficient chip evacuation and surface finish quality in both roughing and finishing operations. The reduced neck profile and variable index flute spacing minimize chatter and vibration during aggressive cuts. It is intended for use by machinists and CNC operators working in production and job-shop environments.

This end mill is engineered specifically for aluminum alloys and non-ferrous metals, making it a go-to tool for aerospace, automotive, and general machining applications where these materials are common. The 2.125 inch reach length and reduced neck diameter of 0.356 inches allow access to deep pockets and contoured surfaces without sacrificing rigidity. The straight-cylindrical shank fits standard ER and side-lock toolholders common in CNC milling setups. It is sold as a single-end tool and ships individually.

Key Features

• 3-flute ball nose geometry supports both roughing and finishing in a single tool
• 40-degree high-helix angle promotes aggressive chip evacuation in aluminum and non-ferrous materials
• Zplus PVD coating reduces built-up edge and extends tool life in non-ferrous applications
• Variable index flute spacing reduces harmonic vibration and chatter
• Reduced neck design provides extended reach of 2.125 inches for deep-pocket milling
• h6 tolerance on both mill diameter and shank diameter ensures consistent, accurate fitment in precision toolholders

Compatibility

Designed for milling aluminum alloys and non-ferrous materials (primary workpiece material code: N). Fits standard straight-cylindrical toolholders accepting a 3/8 inch shank diameter. Suitable for CNC vertical and horizontal milling machines equipped with appropriate collet or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool is properly torqued into the toolholder before operation. Confirm runout does not exceed the specified TIR maximum of 0.0003 inches after installation. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when handling and storing solid carbide tooling.
