Helical Solutions 88176 Ball End Mill 3/16 in 4 Flute Carbide

Product Description

The HELICAL SOLUTIONS 88176 is a solid carbide ball end mill designed for milling operations in steel and ferrous alloys. It features a 3/16 inch diameter with a matching 3/16 inch straight-cylindrical shank, a 3/4 inch length of cut, and a 2.5 inch overall length. The 4-flute, variable-index geometry reduces harmonic vibration during cutting, improving surface finish and tool life. An APLUS coating provides wear resistance and lubricity in steel applications. The 35-degree helix angle promotes efficient chip evacuation. This tool is sized for precision profiling, slotting, and contouring passes where tight tolerances and clean ball-nose radii are required. Machinists and CNC operators in job shops, aerospace, and general manufacturing install and run this tool in vertical or horizontal machining centers.

This end mill is engineered for use in steel and ferrous materials, consistent with its Series designation of Steels - 4 Flute - Ball - Variable Pitch. Typical applications include finish profiling, 3D contouring, and shallow slotting in hardened and unhardened steels. The standard-length configuration suits general-purpose setups where minimal stick-out keeps deflection low. The single-end design makes it a direct load-and-go tool for tool holders accepting 3/16 inch shank diameters. It is well suited to high-speed machining strategies given the variable-index flute spacing and APLUS coating combination.

Key Features

• 4-flute variable-index geometry reduces chatter and harmonic vibration during steel milling
• APLUS coating delivers wear resistance and improved lubricity in ferrous applications
• 35-degree helix angle promotes effective chip evacuation and smooth cutting action
• Solid carbide construction provides rigidity and thermal stability at elevated cutting speeds
• Ball nose profile enables 3D contouring and radius profiling with consistent geometry
• Straight-cylindrical shank fits standard collet and end mill holders for 3/16 inch tooling

Compatibility

Designed for use in machining centers and CNC mills equipped with tool holders accepting a 3/16 inch straight-cylindrical shank. Intended for cutting steel and ferrous alloys as indicated by the Steels - 4 Flute - Ball - Variable Pitch series designation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Verify tool holder runout before seating the shank and torque the collet nut or set screw to the tool holder specification. Minimize stick-out to reduce deflection on this standard-length tool. Confirm spindle is fully stopped and machine is in a safe state before loading or unloading the cutter.
