Helical Solutions 82074 Corner Radius End Mill 6 Flute

Product Description

The HELICAL SOLUTIONS 82074 is a solid carbide corner radius end mill engineered for high-performance material removal in superalloys and titanium. It features a 1/2-inch mill diameter, a 2-inch length of cut, and a 0.0100-inch corner radius. The 6-flute, single-end design with variable pitch delivers both roughing and finishing capability in a single tool. APLUS PVD coating provides thermal and wear resistance required for demanding aerospace and industrial alloy work. Overall length is 4 inches with a 1/2-inch straight cylindrical shank. This tool is part of the HVTI-6 series, purpose-built for titanium and titanium alloy applications.

The 82074 is designed for machining superalloys and titanium, including titanium alloys, in high-precision CNC milling operations. Its right-hand flute direction and right-hand cutting geometry suit vertical and horizontal machining centers. The long-reach, centercutting configuration allows plunge entry and side milling in tight pockets and contoured surfaces. High-precision toolholders are recommended to maintain runout within the 0.0005-inch maximum TIR specification. This tool is suited for production environments where tool life and surface finish in difficult-to-machine materials are critical performance factors.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• APLUS PVD coating optimized for titanium and superalloy cutting
• Variable pitch design reduces harmonic vibration during aggressive cuts
• Centercutting geometry enables direct plunge entry
• 0.0100-inch corner radius protects the cutting edge and improves surface finish at part corners
• Maximum TIR of 0.0005 inches supports tight dimensional tolerances

Compatibility

Intended for use with high-precision toolholders in CNC milling applications targeting titanium and titanium alloy workpieces, consistent with the HVTI-6 series application range.

Installation Notes

Installation and setup should be performed by a qualified CNC machinist or tooling technician. Secure the shank in a high-precision toolholder to maintain runout within specification. Confirm machine spindle and toolholder are clean and free of debris before seating the tool. Follow the cutting tool manufacturer guidance for feeds, speeds, and coolant strategy when programming cuts in titanium and superalloys.
