Helical Solutions 82983 Corner Radius End Mill 1/4 in 5 Flute

Product Description

The HELICAL SOLUTIONS 82983 is a 5-flute solid carbide corner radius end mill designed for high-performance milling in demanding materials including stainless steel, superalloys, and titanium. The HEV-5 series features a variable index geometry and Tplus PVD coating, which reduces heat buildup and extends tool life in difficult-to-machine workpieces. At 1/4 inch diameter with a 0.015 inch corner radius, this tool handles both roughing and finishing operations in a single setup. It is intended for use in high-precision toolholders and is well-suited to machinists running tight-tolerance work in production or job shop environments.

The 82983 is built for applications involving stainless steel, superalloys, titanium, non-ferrous metals, and hard materials. Its single-end, center-cutting design allows plunge entry and full slot cutting. The 3/4 inch length of cut and 2-1/2 inch overall length make it a standard reach tool appropriate for most mold, die, aerospace, and general precision machining setups where corner radius blending and edge strength are required.

Key Features

• Solid carbide construction for rigidity and heat resistance in hard materials
• Tplus PVD coating provides wear resistance and reduced friction in stainless steel and superalloys
• Variable index flute geometry reduces harmonic chatter during aggressive cuts
• 0.015 inch corner radius protects cutting edges and improves surface finish at floor transitions
• Center-cutting design allows direct plunge entry without pre-drilling
• Right-hand cut, right-hand spiral with straight-cylindrical shank for broad toolholder compatibility

Compatibility

Designed for use with high-precision toolholders. Suitable for machining stainless steel, superalloys, titanium, non-ferrous metals, and hard materials. Refer to the HEV-5 series specifications and your toolholder manufacturer guidelines to confirm runout and clamping requirements before use.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before seating the end mill. Confirm runout does not exceed the maximum TIR of 0.0005 inches after clamping. Follow your machine tool manufacturer and shop safety guidelines when setting cutting parameters for the target workpiece material.
