Accupro 72073554 Ball End Mill 3/8 Inch 6 Flute Carbide

Product Description

The ACCUPRO 72073554 is a 6-flute solid carbide ball end mill designed for high-performance milling in demanding materials. With a 3/8-inch mill diameter and AlTiN+ coating, it is built for cutting high-temperature alloys and other difficult workpiece materials. The variable helix geometry, with helix angles of 36 and 40 degrees, reduces chatter and vibration during cutting. The variable index spacing further improves surface finish and tool stability. Center-cutting capability allows direct plunging into workpieces. Licensed machinists and CNC operators use this end mill for contouring, profiling, and 3D milling operations in production and job-shop environments.

This ball end mill suits CNC machining centers handling high-temp alloys, stainless steels, and other S-code materials where tool life and surface integrity are critical. The single-end, straight-shank design fits standard ER and side-lock toolholders accepting a 3/8-inch shank. The 3/4-inch length of cut and 2-1/2-inch overall length make it well suited for moderate-depth cavities, contoured surfaces, and profiling passes where reach and rigidity must be balanced.

Key Features

• 6-flute solid carbide construction for strength and wear resistance in high-temp alloys
• AlTiN+ coating for elevated heat resistance and extended tool life
• Variable helix (36 and 40 degrees) and variable index to reduce chatter and harmonic vibration
• Center-cutting geometry allows direct plunge entry into workpiece material
• Right-hand cut and right-hand flute direction for standard CNC spindle operation
• Single-end, straight shank compatible with common toolholding systems

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 3/8-inch straight shank, with primary suitability for high-temperature alloys (material code S) as specified by the manufacturer.

Installation Notes

Installation and operation should be performed by qualified machinists or CNC operators. Ensure the toolholder and collet are clean and within runout specification before seating the shank. Verify spindle speed and feed rate parameters are set for solid carbide tooling in the target workpiece material before engaging the cut. Never exceed the manufacturer-rated depth of cut or remove the tool from the holder while the spindle is in motion.
