Helical Solutions 88405 Corner Radius End Mill 3/8 in 6 Flute

Product Description

The HELICAL SOLUTIONS 88405 is a 6-flute solid carbide corner radius end mill designed for demanding milling applications in stainless steel and high-temperature alloys. It features a 3/8-inch diameter, a 0.1250-inch corner radius, and a 1-1/4-inch length of cut. The variable-pitch flute geometry helps reduce chatter and vibration during aggressive cuts. With a Tplus coating applied over the carbide substrate, this tool delivers improved wear resistance and heat management in difficult-to-machine materials. Licensed machinists and CNC tooling professionals working in aerospace, medical, and industrial manufacturing will find this end mill suited for high-performance finishing and semi-finishing passes.

This end mill is built for cutting stainless steels and high-temperature alloys where heat buildup and work hardening are primary concerns. The single-end, center-cutting design allows for plunging as well as conventional peripheral milling. The 37-degree helix angle promotes smooth chip evacuation and consistent surface finish. It fits standard 3/8-inch ER or end mill holders with a straight cylindrical shank. This tool belongs to the Helical Solutions Stainless and High Temp 6-Flute Corner Radius Variable Pitch series, purpose-built for production environments requiring tight tolerances and extended tool life.

Key Features

• 6-flute variable-pitch geometry reduces harmonic vibration and chatter during deep cuts
• 0.1250-inch corner radius protects cutting edges and improves surface finish on radii features
• Tplus coating enhances wear resistance and thermal performance in stainless and high-temp alloys
• Center-cutting capable — supports ramping and plunge entry
• Right-hand cutting and right-hand flute direction for standard CNC spindle compatibility
• Solid carbide construction provides rigidity and dimensional stability under high cutting loads

Compatibility

Designed as part of the Helical Solutions Stainless and High Temp 6-Flute Corner Radius Variable Pitch series, intended for machining stainless steels and high-temperature alloys with a 3/8-inch straight cylindrical shank compatible with standard ER collet chucks and end mill holders.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Secure the shank fully into the holder to the recommended gauge length and verify runout before cutting. Ensure the machine spindle is at a full stop before changing tooling. Follow the tool manufacturer cutting parameter recommendations for the specific workpiece material to avoid premature edge wear or breakage.
