Helical Solutions 82680 High-feed End Mill 3mm 4-flute

Product Description

The HELICAL SOLUTIONS 82680 is a single-end, high-feed end mill designed for aggressive material removal in steels up to 45 Rc. Built from solid carbide with a Tplus coating, this 4-flute tool features a reduced neck profile and variable pitch flute geometry that suppresses chatter during high-feed-rate passes. The 3 mm mill diameter and 0.38 mm program radius make it well suited for small-feature milling, tight-pocket work, and die-mold applications where maintaining rigidity in a compact tool diameter is critical. CNC machinists and tool-and-die shops specify this geometry for high-speed, low-depth-of-cut strategies that maximize material removal without overloading the spindle.

This end mill is intended for use on CNC machining centers running high-feed milling programs in ferrous materials rated up to 45 Rc hardness. The reduced neck construction allows for extended reach into deep pockets while minimizing deflection. The 18 mm reach length and 3 mm length of cut are matched to shallow axial depth passes at elevated feed rates, a toolpath strategy common in hard-part milling, mold cavity roughing, and fine-feature finishing in tool steels and alloy steels.

Key Features

• Solid carbide construction for rigidity and wear resistance in hardened steels
• Tplus coating enhances heat resistance and extends tool life in ferrous materials
• Variable pitch flute geometry reduces harmonic chatter at high feed rates
• Reduced neck profile enables extended reach into deep pocket features
• 4-flute design balances chip evacuation and cutting edge count for high-feed strategies
• 0.38 mm program radius geometry optimized for high-feed, low-axial-depth toolpaths

Compatibility

Designed for use in steels up to 45 Rc on CNC machining centers. Part of the Helical Solutions High Feed End Mills - Steels up to 45 Rc - Metric - Variable Pitch - Reduced Neck series.

Installation Notes

Installation and tool changes must be performed with the machine powered down and the spindle fully stopped. Use a calibrated tool holder and collet sized for the 3 mm shank diameter to ensure proper runout and clamping force. Verify toolpath program radius settings match the 0.38 mm specification before running. Follow the machine manufacturer and tooling manufacturer guidelines for speeds, feeds, and toolholder torque specs appropriate to this tool diameter.
