Helical Solutions 46626 Square End Mill 3/4 in 3 Flute

Product Description

The HELICAL SOLUTIONS 46626 is a 3-flute solid carbide square end mill engineered for high-performance milling of aluminum and non-ferrous materials. It carries a 0.75 inch mill diameter with a matching 0.75 inch straight shank and a 1.0 inch length of cut. The Zplus ZrN coating reduces built-up edge and improves chip flow in gummy non-ferrous alloys. A 40-degree helix angle combined with a variable index pitch pattern lowers harmonics and chatter during aggressive cuts. The extended-reach neck extends usable reach to 5.0 inches, making it well suited for deep-pocket and thin-wall features. Center-cutting geometry allows direct plunge entry. Right-hand cut and right-hand flute direction are standard.

This end mill is intended for use in CNC machining centers, vertical mills, and high-speed machining applications where aluminum alloys, brass, copper, and other non-ferrous materials are the primary workpiece. The reduced-neck, extended-reach design is particularly useful for aerospace, mold, and die work where deep cavities or tall part features require clearance beyond what a standard-length tool provides. It is a single-end tool sold individually and is sized for direct use in standard 3/4 inch collets and end mill holders.

Key Features

• 0.75 inch mill diameter with 0.75 inch straight shank for direct fitment in standard holders
• 3-flute geometry optimized for chip evacuation in aluminum and non-ferrous materials
• Zplus ZrN coating reduces friction and resists built-up edge on sticky alloys
• 40-degree helix angle promotes smooth cutting action and reduced axial forces
• Variable index flute spacing lowers vibration and chatter at aggressive feed rates
• 5.0 inch extended reach with reduced neck for deep-pocket and tall-feature applications
• Center-cutting design allows plunge and ramp entry without a pre-drilled hole

Compatibility

Designed for use in CNC machining centers and manual mills with standard 3/4 inch collet chucks, hydraulic holders, or shrink-fit holders. Primary workpiece materials are aluminum and non-ferrous metals per the manufacturer designation. Part of the HELICAL SOLUTIONS End Mills for Aluminum series: 3 Flute, Square, 40 degree Helix, Variable Pitch, Reduced Neck.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank to the full recommended gauge-line depth in a balanced tool holder and verify runout before cutting. Power down and lock out the spindle before changing or measuring tooling. Follow the machine tool manufacturer torque specifications for the specific holder style in use.
