Helical Solutions 83098 Corner Radius End Mill 5 Flute

Product Description

The HELICAL SOLUTIONS 83098 is a 5-flute, solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. It features a 0.25-inch mill diameter, a 0.75-inch length of cut, and a 0.50 mm (0.0200 inch) corner radius that reduces stress concentration at the cutting edge. The Tplus PVD coating enhances wear resistance and thermal stability. With a variable pitch, right-hand spiral flute geometry, chipbreaker design, and centercutting capability, this tool is built for roughing and semi-finishing operations in stainless steel, high-temperature alloys, and hardened steels.

The 83098 is suited for CNC machining centers running tight-tolerance work in aerospace, medical, die and mold, and general precision manufacturing. The straight cylindrical 0.25-inch shank is compatible with high-precision toolholders. Its regular-length configuration fits standard reach applications. The tool is engineered for right-hand cutting with a variable pitch to suppress chatter and improve surface finish in difficult-to-machine materials including stainless steel, high-temperature alloys, and hardened steel up to the H material group classification.

Key Features

• 5-flute variable-pitch geometry reduces chatter in stainless and high-temp alloys
• Tplus PVD coating improves wear resistance and tool life in abrasive materials
• 0.50 mm corner radius (0.0200 inch) provides edge strength and reduces workpiece stress risers
• Chipbreaker design aids chip evacuation during roughing passes
• Centercutting capable for plunge entry operations
• Solid carbide construction maintains rigidity at elevated cutting speeds

Compatibility

Designed for use with high-precision toolholders. Primary workpiece materials include stainless steel, high-temperature alloys, and hardened steel. Secondary workpiece materials include steel and cast iron. Part of the HEV-C-5 series.

Installation Notes

Installation is performed by machinists or CNC setup technicians. The 0.25-inch straight cylindrical shank should be seated in a high-precision collet or toolholder to maintain TIR within specification. Verify toolholder runout before use, as excessive runout accelerates flute wear on small-diameter carbide tools. Handle solid carbide end mills carefully to avoid chipping the cutting edges during setup or storage.
