Accupro 72074511 Corner Radius End Mill 3/8 in 6 Flute

Product Description

The ACCUPRO 72074511 is a solid carbide corner radius end mill engineered for demanding material removal in high-temperature alloys and similarly difficult workpiece materials. With a 3/8-inch mill diameter, six flutes, and an AlTiN+ coating, this tool delivers aggressive chip evacuation and heat resistance in a single-end configuration. The 0.020-inch corner radius protects the cutting edge under load and extends tool life in interrupted or finishing cuts. Variable index and variable helix geometry reduce chatter and improve surface finish across a range of cutting conditions. This cutter is used by machinists in precision manufacturing, aerospace, and job shop environments.

This end mill is suited for milling high-temperature alloys (material code S), including nickel-based superalloys, titanium, and stainless steel commonly found in aerospace and industrial components. The right-hand flute direction and right-hand cutting action are standard for conventional CNC milling setups. The center-cutting geometry allows plunge entry, adding versatility for pocketing and profiling operations without a separate drilling operation.

Key Features

• Solid carbide construction for rigidity and heat resistance in difficult alloys
• AlTiN+ coating provides oxidation resistance at elevated cutting temperatures
• Variable helix and variable index geometry reduce harmonic vibration and chatter
• 0.020-inch corner radius extends cutting edge life and improves corner durability
• Center-cutting design allows direct plunge milling
• Six-flute configuration supports high feed rates and fine surface finishes

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 3/8-inch shank. Primary workpiece material designation is high-temperature alloy (S). Belongs to ACCUPRO Series HS.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Secure the shank in a collet or endmill holder rated for the shank diameter of 3/8 inch and verify runout before cutting. Consult machine tool documentation and cutting data charts for appropriate speeds, feeds, and depth of cut for the specific workpiece material. Never exceed the tool manufacturer's recommended parameters for coated solid carbide tooling.
