Accupro 72076326 3/8 Inch 6 Flute Solid Carbide Square End Mill

Product Description

The ACCUPRO 72076326 is a solid carbide square end mill designed for high-performance material removal in demanding machining applications. This single-end tool features a 3/8 inch (0.375 inch) cutting diameter and six helical flutes with a variable helix angle between 36 and 40 degrees and variable index spacing. The AlTiN+ coating provides thermal resistance and extended tool life when cutting hard and abrasive materials. Right-hand cutting and right-hand flute direction are standard. Centercutting geometry allows plunge entry. Intended for use by machinists and tool-and-die professionals working in CNC milling environments.

This end mill is specifically suited for cutting high-temperature alloys (material code S), including nickel-based, cobalt-based, and titanium alloys commonly found in aerospace, medical, and energy industry components. The variable helix and variable index geometry help reduce chatter and harmonics during aggressive cuts. With a 3/4 inch length of cut and 2-1/2 inch overall length, it fits standard toolholding for tight-clearance and shoulder milling operations. No coolant-through capability; external flood or mist coolant is the appropriate cooling method for this tool.

Key Features

• Solid carbide construction for rigidity and wear resistance in abrasive materials
• AlTiN+ coating for elevated thermal performance in high-temp alloy cutting
• Variable helix (36-40 degrees) and variable index for chatter reduction
• Six-flute design increases feed rate capability and improves surface finish
• Centercutting geometry allows direct plunge milling
• Single-end tool in the HS series, fractional inch system

Compatibility

Designed for use in CNC machining centers with standard 3/8 inch tool holders or collets. Primary workpiece material is high-temperature alloy (material code S). No specific machine model compatibility was provided in the product data.

Installation Notes

Installation requires a clean, properly sized collet or toolholder sized for a 3/8 inch shank. Always ensure the machine spindle is fully stopped and the tool is secured to the manufacturer-specified clamping torque for the holder type in use before operation. Inspect the cutting edges for chips or wear before each use. External coolant should be directed at the cutting zone; this tool does not support coolant-through delivery.
