Helical Solutions 34092 Corner Radius End Mill 3/16 in 5 Flute

Product Description

The HELICAL SOLUTIONS 34092 is a solid carbide corner radius end mill engineered for demanding metal removal in both roughing and finishing operations. The tool measures 3/16 inches in diameter with a 3/4-inch length of cut and a 2.5-inch overall length. A 0.01-inch corner radius reduces stress concentrations at the cutting edge and extends tool life in interrupted cuts. Five helical flutes with a variable index pitch improve chip evacuation and reduce harmonic chatter during aggressive passes. The APLUS PVD coating adds wear resistance and thermal stability, making this end mill well suited for high-speed machining environments where tool consistency is critical.

This end mill is designed for milling steel and cast iron as primary workpiece materials, with secondary suitability for stainless steel, non-ferrous metals, superalloys, and titanium. It is a single-end, centercutting tool, meaning it can be fed axially into a workpiece as well as laterally. The straight cylindrical shank accepts high-precision toolholders. The medium-length flute geometry and right-hand cutting direction make it a practical choice for production machining, die and mold work, and general-purpose contouring on CNC mills and machining centers.

Key Features

• Solid carbide construction provides rigidity and edge retention in ferrous and difficult-to-machine materials
• 5-flute variable index design reduces chatter and supports both roughing and finishing in a single tool
• APLUS PVD coating improves wear resistance and thermal performance at elevated cutting speeds
• 0.01-inch corner radius extends tool life and reduces edge chipping on sharp-cornered pockets and profiles
• Centercutting geometry allows direct axial plunging without a pre-drilled entry hole
• Right-hand helical flutes promote efficient chip evacuation in slotting and peripheral milling

Compatibility

Designed for use with high-precision toolholders. Part of the HELICAL SOLUTIONS HEV-5 series. Compatible with CNC milling machines and machining centers that accept a 3/16-inch straight cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool changer is disabled before loading or unloading the end mill. Seat the shank fully and evenly in a high-precision collet or toolholder to maintain runout within the specified TIR maximum of 0.0005 inches. Verify clamping torque per the toolholder manufacturer specifications before beginning a cut.
