Helical Solutions 46495 Square End Mill 5/8 in 3 Flute Carbide

Product Description

The HELICAL SOLUTIONS 46495 is a solid carbide square end mill designed for high-performance aluminum milling. It features a 5/8-inch cutting diameter, a 3/4-inch length of cut, and three flutes arranged in a variable-index configuration that reduces harmonic vibration during aggressive cuts. The 40-degree helix angle promotes efficient chip evacuation, which is critical when machining aluminum alloys. A reduced-neck geometry extends reach to 3.375 inches while maintaining rigidity. This end mill ships uncoated with a bright finish and is built for professional machinists running CNC mills in production or job-shop environments.

This end mill is engineered for aluminum milling applications where chip load management and surface finish matter. The variable-pitch flute spacing minimizes chatter at higher feed rates and spindle speeds typical of aluminum work. The straight cylindrical shank measures 5/8 inch in diameter, fitting standard ER and side-lock toolholders. The 6-inch overall length and extended-reach design make it suitable for reaching into deeper pockets or stepped features without sacrificing cut stability. It is a single-end tool intended for right-hand cutting with right-hand flute direction.

Key Features

• 5/8-inch cutting diameter with 3/4-inch length of cut for controlled material removal
• Three-flute variable-index design reduces vibration and chatter during aluminum cuts
• 40-degree helix angle promotes aggressive chip evacuation in aluminum
• Reduced-neck geometry provides 3.375 inches of reach for deep-pocket access
• Center-cutting capable, allowing direct plunge entry
• Solid carbide construction throughout for rigidity and wear resistance
• Bright uncoated finish suited for aluminum where coating adhesion can cause built-up edge

Compatibility

Designed for use in the HELICAL SOLUTIONS End Mills for Aluminum series, 3-Flute Square 40-degree Helix Variable Pitch Reduced Neck configuration. Fits standard 5/8-inch straight cylindrical toolholders used in CNC machining centers.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom personnel. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully in the toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before production cuts to protect both the tool and the workpiece.
