Helical Solutions 82971 Corner Radius End Mill 1/8 in 5 Flute

Product Description

The HELICAL SOLUTIONS 82971 is a 5-flute solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. It features a 1/8 inch mill diameter, a 3/4 inch length of cut, and a 0.0100 inch corner radius with a tolerance of -0.0020 to 0.0020 inches. The Tplus PVD coating provides enhanced wear resistance and surface protection during cutting. With a variable pitch design and right-hand flute direction, this tool balances roughing and finishing operations in a single pass. It is centercutting and accepts straight-cylindrical shank mounting in high precision toolholders.

This end mill is engineered primarily for stainless steel, superalloys, and titanium - materials that demand sharp geometry, tight tolerances, and a durable coating to manage heat and tool wear. Secondary applications include non-ferrous metals and hard materials. The HEV-5 series is suited for CNC machining centers where precision tolerances and surface finish quality are critical. The single-end configuration and standard length type make it a practical choice for general-purpose milling operations in both prototype and production environments.

Key Features

• 5-flute solid carbide construction for rigidity and heat resistance in tough alloys
• Tplus PVD coating rated for stainless steel, superalloys, and titanium applications
• Variable pitch design reduces harmonic vibration during cutting
• 0.0100 inch corner radius protects cutting edges and improves part surface finish
• Centercutting geometry allows plunge entry into workpieces
• TIR maximum of 0.0005 inches for high-precision runout control

Compatibility

Designed for use with high precision toolholders. Part of the HELICAL SOLUTIONS HEV-5 series. Intended for CNC milling applications involving stainless steel, superalloys, titanium, non-ferrous metals, and hard materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank in a high precision toolholder to maintain the specified TIR maximum of 0.0005 inches. Verify spindle and toolholder are clean and free of debris before seating the tool. Follow machine tool manufacturer torque and clamping specifications for the toolholder type in use.
