Helical Solutions 84061 Corner Radius End Mill 1/16 in 5 Flute

Product Description

The HELICAL SOLUTIONS 84061 is a 5-flute solid carbide corner radius end mill designed for high-performance finishing in stainless steel, superalloys, titanium, and hardened steel. It features a 0.0625-inch mill diameter, a 0.01-inch corner radius, and a 0.1875-inch length of cut. The variable-pitch flute geometry reduces harmonic vibration during high-speed machining (HSM) cycles, making it well suited for tight-tolerance profiling and contour finishing. The Tplus PVD coating provides elevated wear resistance and thermal stability in demanding material applications. This tool is intended for use in CNC machining centers with high-precision toolholders.

The 84061 is optimized for finishing operations on stainless steel, high-temperature alloys, and hardened materials, with secondary capability in steel and cast iron. Its medium-length geometry and 0.25-inch straight cylindrical shank make it compatible with standard precision collet chucks and hydraulic toolholders commonly used in aerospace, medical, and general precision machining environments. The single-end, centercutting design supports both peripheral and plunge entry. Right-hand cut and right-hand flute direction are standard for conventional CNC milling setups.

Key Features

• 5-flute variable-pitch design reduces chatter and supports higher feed rates in difficult materials
• 0.01-inch corner radius protects the cutting edge and improves surface finish on profiled walls
• Tplus PVD coating delivers extended tool life in stainless steel and high-temperature alloy cuts
• Centercutting construction allows direct plunge entry without a pre-drilled pilot hole
• Solid carbide construction maintains rigidity and dimensional accuracy at elevated spindle speeds
• HSM-5 series geometry engineered specifically for high-speed machining strategies

Compatibility

Designed for use with high-precision toolholders. Primary workpiece materials are stainless steel, superalloys, and titanium; secondary workpiece materials include steel and cast iron. For use in CNC machining centers capable of high-speed milling strategies.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the 0.25-inch shank fully in a high-precision collet or hydraulic toolholder to meet the 0.0005-inch maximum TIR specification. Do not exceed the toolholder manufacturer's recommended clamping torque or runout tolerance for this shank diameter.
