Helical Solutions 84052 Square End Mill 1/8 in 4 Flute Carbide

Product Description

The HELICAL SOLUTIONS 84052 is a 4-flute solid carbide square end mill designed for high-performance milling in steel, stainless steel, and cast iron. With a 0.1250-inch mill diameter and a 0.5000-inch length of cut, this tool delivers precise material removal in demanding ferrous and high-temp alloy applications. The variable index flute spacing reduces harmonic chatter during the cut, and the Tplus coating improves wear resistance and heat dissipation. A 35-degree helix angle promotes efficient chip evacuation and smooth surface finishes. This end mill is a single-end, center-cutting design, meaning it can plunge directly into the workpiece as well as perform conventional side milling.

This end mill fits standard CNC machining centers and manual mills using a 0.2500-inch straight shank. It is part of the HELICAL SOLUTIONS End Mills for Stainless and High Temp 4 Flute Square Variable Pitch series, making it well suited for shops running tight-tolerance work in 300-series stainless, alloy steels, and gray or ductile cast iron. Its compact 0.1250-inch diameter is appropriate for finishing passes, slot milling, and contour work in complex part geometries where a smaller tool is required.

Key Features

• Solid carbide construction for rigidity and thermal stability in ferrous materials
• Tplus coating reduces friction and extends tool life in stainless and high-temp alloys
• Variable index flute spacing minimizes chatter and vibration during aggressive cuts
• 35-degree right-hand helical flutes promote efficient chip flow and surface finish quality
• Center-cutting geometry allows direct plunge entry without a pre-drilled pilot hole
• Single-end design with a 0.2500-inch straight shank for broad machine compatibility

Compatibility

Designed for use in CNC machining centers and manual mills with a 0.2500-inch collet or end mill holder. Primary workpiece materials are steel, stainless steel, and cast iron as specified by the manufacturer for this series.

Installation Notes

This tool should be installed by a qualified machinist or CNC operator using a properly sized collet or end mill holder rated for the 0.2500-inch shank diameter. Confirm the spindle is fully stopped and locked out before changing tooling. Use appropriate cutting speeds and feeds for the workpiece material and verify runout with a dial indicator before beginning a production run. Do not exceed the rated length of cut when taking full-depth axial passes.
