Helical Solutions 84089 Square End Mill 3/32 in 5 Flute Carbide

Product Description

The HELICAL SOLUTIONS 84089 is a 5-flute solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. With a 3/32-inch (0.0937-inch) mill diameter and a 9/32-inch (0.281-inch) length of cut, this tool is built for fine-feature work in tight geometries. The Tplus coating improves lubricity and wear resistance, extending tool life in demanding cutting conditions. A variable index flute spacing reduces harmonic vibration during the cut, contributing to better surface finish and reduced chatter. Single-end configuration with a straight-cylindrical 1/4-inch shank makes this a direct-mount tool for standard collet and end mill holder setups.

This end mill is suited for high-precision milling applications in job shops, aerospace component machining, die and mold work, and production environments where small-diameter tooling is required. The 5-flute geometry supports higher feed rates compared to standard 4-flute tools in finishing passes. The 2-1/2-inch overall length provides enough reach for most small-feature pocket and contour work without sacrificing rigidity. Right-hand cutting and right-hand helical flutes are standard for conventional CNC milling center setups.

Key Features

• 5-flute solid carbide construction for strength and heat resistance in demanding cuts
• Tplus coating for improved wear resistance and reduced friction
• Variable index flute spacing reduces chatter and improves surface finish
• Center-cutting capable, allowing plunge entry into workpiece material
• Right-hand cut with helical flute geometry for efficient chip evacuation
• Straight-cylindrical shank fits standard collet chucks and end mill holders

Compatibility

Designed as a direct-mount replacement or new-install square end mill for CNC machining centers and manual mills equipped with a 1/4-inch collet or end mill holder accepting a straight-cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully powered down and locked before inserting or removing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth before tightening. Verify runout with an indicator after mounting before beginning any cut.
