Karbosan 910860 NK Flat Metal Cutting Disc 350x3.5x25.4 mm

Karbosan NK Flat Metal Cutting Disc 350x3.5x25.4 mm

The Power of Heavy-Duty Cutting Machines

Karbosan NK Flat Metal Cutting Disc is a heavy-duty abrasive disc specifically designed for the largest and most powerful fixed or portable industrial cutting saws (construction saws and chop saws) on the market.

With an outer diameter of 350 mm (approximately 14 inches), it offers maximum cutting depth and single-pass cutting capacity for the thickest industrial-sized profiles, pipes, and iron materials. The 3.5 mm thickness is engineered to withstand the high power and lateral loads exerted on a disc of this size, ensuring long life and stability. Its high-quality Normal Corundum (NK) abrasive grains perform high-speed and reliable cuts on iron, steel, and various standard metals. The 25.4 mm (1 inch) bore diameter is perfectly compatible with the standard arbor diameter of such industrial fixed cutting machines.

Application Areas and Industries Where It Is Used:

The Karbosan NK 350 mm Cutting Disc is used in industrial sectors where the serial, precise, and safe cutting of the thickest and largest metal materials is performed on fixed saws:

Industries

Heavy Steel Construction and Building: Precise sizing of thick-walled steel beams (I, H profiles), columns, large-diameter steel bars, and structural elements in the workshop or on-site.

Machine Manufacturing and Fabrication: Cutting of parts required for industrial machine chassis, heavy lifting equipment, and thick metal support legs.

Piping and Pipelines (Heavy Duty): Accurate cutting of the largest diameter steel pipelines and thick piping profiles.

Iron Casting and Foundries (Cleaning): Powerful and rapid cutting of sprues and excess metal residues from cast parts (on appropriate saws).

General Metal Fabrication: Large workshops seeking efficiency and durability in high-volume and continuous cutting operations.

Applications

Maximum Cutting Capacity: With the depth provided by its 350 mm diameter, it can powerfully cut the widest and thickest metal profiles, which 300 mm discs cannot handle, in a single pass.

Mass Production Precision: Thanks to the precise settings of the fixed cutting saw, it minimizes waste even on thick materials, achieving perfect angles for welding preparation.

Long-Lasting Operation: The 3.5 mm thickness maximizes disc life and withstands high cutting forces, supporting uninterrupted operation in industrial environments.

Fast and Efficient Cutting: The aggressiveness of the NK abrasive combined with a high-power fixed machine significantly shortens cutting time even on thick metals.

About the Product

350 mm: The Pinnacle of Industrial Cutting

350 mm Diameter: Tackling the Thickest Profiles

A 350 mm diameter in metal cutting discs is a size that hand tools cannot reach, usable only by the most powerful fixed or portable industrial cutting machines. This disc is designed for the high-efficiency, single-pass cutting of the thickest steel pipe and profile materials, a fundamental need in sectors such as heavy steel construction and large-scale metal fabrication. This capacity translates into time and material savings in large projects.

3.5 mm Thickness: Guarantee of Safety and Continuity

For a large diameter like 350 mm, disc stability and safety are vital. The 3.5 mm thickness ensures that this disc maintains maximum lateral stability even under the high torque and thrust force applied by the fixed machine. This prevents the disc from bending or breaking during cutting, increasing operator safety and providing a clean and straight cut line on the material. The Normal Corundum (NK) abrasive maintains consistent and reliable cutting performance on standard construction and structural metals like steel and iron for a long time.

Wide Compatibility with 25.4 mm Bore Standard

The 25.4 mm (1 inch) bore diameter ensures that this disc is fully compatible with many popular industrial cutting machine brands in the international and local markets. This standard compatibility means that workshops can use the same consumable even if they have different machines, which simplifies inventory management and increases operational flexibility.

The Karbosan NK Flat Metal Cutting Disc 350x3.5x25.4 mm, thanks to its superior cutting capacity provided by the 350 mm diameter, maximum durability offered by the 3.5 mm thickness, and industrial standard bore compatibility, provides unrivaled performance and expertise for the serial, precise, and safe cutting of the thickest metal materials in the heavy steel construction, machine manufacturing, and large piping sectors.
