Helical Solutions 84839 Corner Radius End Mill 1/2 in Carbide

Product Description

The HELICAL SOLUTIONS 84839 is a solid carbide corner radius end mill designed for high-performance material removal in aluminum and non-ferrous metals. It features a 1/2 inch mill diameter, a 1-1/4 inch length of cut, and a 3 inch overall length. The 35-degree medium helix angle and three-flute geometry with variable pitch and chipbreaker promote efficient chip evacuation and reduced chatter during aggressive cuts. The Zplus PVD coating provides wear resistance suited to aluminum and non-ferrous applications. The corner radius measures 0.125 inches, reducing stress concentration at the cutting edge and extending tool life in roughing operations.

This end mill fits standard straight-cylindrical shank toolholders with a 1/2 inch shank diameter and is recommended for use with high-precision toolholders to maintain the 0.0003 inch maximum TIR specification. It is centercutting, enabling plunge entry, and carries a right-hand flute direction with right-hand cutting direction. While optimized for aluminum and non-ferrous metals, the H35ALV-C-3 series is also rated for secondary use in steel, stainless steel, cast iron, high temperature alloys, and hard materials. Typical applications include roughing passes in CNC machining centers in both job shop and production environments.

Key Features

• Solid carbide construction with Zplus PVD coating for aluminum and non-ferrous metal cutting
• Three-flute variable-pitch design with chipbreaker for reduced chatter and efficient chip evacuation
• 0.125 inch corner radius reduces edge stress and extends tool life in roughing operations
• Centercutting geometry allows direct plunge entry without pre-drilling
• 35-degree medium helix angle balances cutting forces across a range of materials
• Mill diameter and shank diameter held to h6 tolerance for consistent fit in precision toolholders

Compatibility

Designed for use with high-precision toolholders accepting a 1/2 inch straight-cylindrical shank. Series H35ALV-C-3. Primary workpiece material: aluminum and non-ferrous metals. Secondary workpiece materials include steel, stainless steel, cast iron, high temperature alloys, and hard materials.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before loading or changing the tool. Seat the shank fully in a high-precision collet or toolholder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout does not exceed the 0.0003 inch maximum TIR before beginning a cut.
