R8 Face Mill, 400R 80MM 90° Face Mill Arbor, R8 FMB27 7/16-20UNF Thread Shank, 10Pcs APMT1604 Carbide Inserts and T15 Wrench (80-6T)

Product DescriptionThe 400R-80-22-4T face milling cutter is a high-performance industrial tool engineered for users who demand efficiency, precision, and cutting stability. Featuring a standard 80mm (3.15-inch) cutting diameter and a 6-flute design, it supports high-feed, heavy-duty milling operations—making it ideal for surface finishing, rough cutting, and large-area machining. The 22mm center bore allows for straightforward installation on various tool holders and spindles, offering convenience and a compact, rigid structure for reliable operation.This cutter is compatible with APMT1604 indexable carbide inserts, enabling fast insert replacement and versatile application across multiple materials. Whether you're working with molds, automotive components, or mechanical parts, this face milling cutter is a dependable solution for consistent cutting performance and efficient throughput.Recommended ApplicationsCNC machining centersMold making and tool fabricationBatch processing of mechanical componentsMilling of automotive and motorcycle partsSurface machining of industrial equipmentStainless steel pipe flanges and fittings

• Four-slot high-efficiency cutting structure: This R8 face milling cutter adopts a classic four-slot design, allowing for the simultaneous installation of four APMT1604 inserts to achieve multi-edge simultaneous cutting, significantly enhancing the cutting volume and chip removal efficiency within a unit of time. It is suitable for batch processing scenarios with rapid tool feed and high-speed feed, significantly reducing the working hours per piece and lowering processing costs.
• 80MM Standard cutting diameter: 80mm The overall outer diameter of the milling cutter is 80mm (3.15 inches), which is a common practical size in industrial processing. It is suitable for face milling, step milling, plane finishing and other processes of medium and large-sized workpieces, and is applicable to multiple working conditions such as mold manufacturing, automotive parts, mechanical shells, and steel structural components.
• Alloy steel knife body: The body of the face milling cutter is forged from high-toughness and high-strength alloy steel, and the entire cutter ffers reliable performance under heavy-duty and high-speed conditions. Even under the conditions of heavy cutting and high-speed feed, the structure of the tool head can still remain stable. The surface treatment layer supports longer tool lifeof the tool body and reduces the loss of labor or replacement costs caused by the damage of the tool head.
• Replace the flexible blade structure: This R8 face milling cutter adopts a standard APMT1604 hard alloy (HRC30-55) interchangeable insert structure. Users can select inserts of different material grades according to the material being processed. The blade is firmly installed with M4×10 clamping screws, allowing for quick disassembly and assembly. There is no need to scrap the entire blade; only the blade needs to be replaced, ensuring efficient maintenance.
• Precision dynamic balancing processing: The R8 face milling cutter, when paired with an R8 shank, effectively reduces the radial runout and vibration of the cutter head during rotation, thereby increasing the longer tool life of the machine tool spindle and enhancing the cutting stability. The cutting process runs smoothly, ensuring uniform and smooth processing surface quality of the workpiece and effectively reducing the workload of subsequent polishing processes.
