Accupro 72031081 Corner Radius End Mill 3/4 in 6 Flute

Product Description

The ACCUPRO 72031081 is a solid carbide corner radius end mill designed for high-performance milling in demanding applications. Built with a 0.75-inch mill diameter and a 0.25-inch corner radius, this single-end tool carries six flutes with a variable helix and variable index geometry. The AlTiN+ coating provides thermal resistance and extended tool life when cutting hard and abrasive materials. It is center-cutting and runs in a right-hand cutting direction, making it suitable for plunge, slot, and contour operations. Machinists in production and job-shop environments rely on tools like this for consistent results in difficult workpiece materials.

The 72031081 is engineered for cutting high-temperature alloys, designated by workpiece material code S. This includes nickel-base, cobalt-base, and titanium alloys commonly found in aerospace, medical, and power-generation components. The variable helix geometry reduces chatter and harmonics during deep cuts, and the variable index spacing further dampens vibration. The 1.25-inch length of cut and 4-inch overall length make it appropriate for moderate-depth passes where rigidity and chip evacuation are both critical.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-temp alloy cutting
• AlTiN+ coating for elevated thermal resistance and extended tool life
• Variable helix and variable index geometry reduce chatter and vibration
• 0.25-inch corner radius protects the cutting edge and reduces stress concentration at corners
• Center-cutting design allows direct plunge entry
• Six-flute configuration supports higher feed rates in stable setups

Compatibility

Designed for use in CNC machining centers and manual mills with a 3/4-inch collet or end mill holder. Primary workpiece material is high-temperature alloy (material code S), including nickel, cobalt, and titanium alloys.

Installation Notes

Installation should be performed by a qualified machinist following shop-standard toolholding procedures. Ensure the shank is fully seated and secured in a clean, undamaged collet or shrink-fit holder before running. Verify spindle speed, feed rate, and depth of cut against tooling data before engaging the cut. Do not exceed the tool's rated length of cut when side-milling without reducing chip load accordingly.
