Helical Solutions 83187 Square End Mill 1/8 in 4 Flute Carbide

Product Description

The HELICAL SOLUTIONS 83187 is a 4-flute solid carbide square end mill designed for demanding cutting applications in stainless steel, steel, and cast iron. With a 1/8 inch (0.1250 inch) mill diameter and 3/4 inch (0.7500 inch) length of cut, this single-end tool delivers precise material removal in tight geometries. The variable index design reduces harmonic vibration during cutting, contributing to improved surface finish and extended tool life. A Tplus coating enhances wear resistance and heat tolerance, making this end mill well-suited for the elevated temperatures generated when machining high-temp alloys and stainless grades.

This end mill is used in CNC milling applications where close-tolerance work in stainless steel, alloy steel, or cast iron is required. The 1/8 inch shank diameter fits standard collet chucks commonly used on vertical machining centers and CNC routers. It is appropriate for finish profiling, slotting, and side milling passes in both production shop and job shop environments. The 35-degree helix angle and right-hand flute direction make it compatible with conventional climb-milling strategies on modern CNC equipment. Machinists and CNC operators working with difficult-to-machine ferrous materials will find this tool geometry appropriate for their applications.

Key Features

• 4-flute solid carbide construction for rigidity and wear resistance in ferrous materials
• Variable index flute spacing reduces vibration and chatter during aggressive cuts
• Tplus coating improves heat resistance and extends tool life in stainless and high-temp alloys
• 35-degree helix angle optimized for right-hand cutting direction
• Center-cutting design allows plunge entry as well as peripheral milling
• Straight shank fits standard 1/8 inch collet or end mill holder

Compatibility

Designed for use in steel, stainless steel, and cast iron applications. Part of the HELICAL SOLUTIONS End Mills for Stainless and High Temp 4-Flute Square Variable Pitch series. Fits any standard 1/8 inch collet or tool holder.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine spindle fully stopped and the control in an e-stop or lockout state. Ensure the collet or tool holder is clean and free of chips before seating the shank to the full recommended insertion depth. Verify runout with a dial indicator before first use, as excessive runout on a 1/8 inch diameter tool will significantly shorten tool life. Follow the tooling manufacturer and machine builder guidelines for speeds, feeds, and depth of cut for the specific workpiece material.
