Karbosan NK Flat Metal Cutting Disc 230x3.0x22 mm

Karbosan NK Flat Metal Cutting Disc 230x3.0x22 mm

Maximum Cutting Depth and Industrial Power

The Karbosan NK Flat Metal Cutting Disc is a high-performance abrasive disc, designed specifically for cutting large and heavy metal parts. It is used with professional angle grinders (spirals) of 230 mm (9 inches).

Its 230 mm outer diameter offers the user maximum cutting depth, enabling the cutting of thick pipes, wide profiles, and large metal sheets in a single pass. The 3.0 mm thickness provides high durability and long life, designed to accommodate high-powered 230 mm machines. With high-quality Normal Corundum (NK) abrasive grains, it performs fast, clean, and reliable cuts on various metals, especially iron and steel. The 22 mm inner diameter is fully compatible with standard large angle grinders.

Usage Areas and Industries Served

The Karbosan NK 230 mm Cutting Disc is used in industrial sectors where the cutting of the thickest and largest metal parts is required, and where power and efficiency are paramount:

Sectors

Heavy Construction and Structural Steel: Cutting large diameter steel beams, I and H profiles, thick steel plates, and heavy load-bearing elements.

Shipbuilding and Shipyards: Sizing thick ship plates and large pipe passages.

Machine Manufacturing and Boiler Industry: Cutting and preparing large machine chassis, industrial equipment, and thick metal plates.

Pipelines and Industrial Installations: Assembly and disassembly of high-pressure and large-diameter steel pipelines.

Railways and Rail Transport: Cutting and adjusting rails and connecting elements.

Applications

Maximum Cutting Depth: Due to the large diameter of the disc, it can cut materials of thickness that other discs cannot cut in a single pass.

Large Profile Cutting: Fast and powerful cutting of the widest metal profiles and box sections, combined with the power of a 230 mm machine.

Industrial Demolition/Dismantling: Dismantling and scrapping thick metal structures.

Continuous Operation: The durable 3.0 mm thickness maintains disc performance even during long cutting lines.

About the Product

230 mm: Single-Pass Power on Thick Metal

Advantage of Large Diameter

230 mm cutting discs represent the highest cutting power and depth offered by angle grinders. This size, combined with high-powered machines, allows for the fast and efficient processing of thick metals, which is critical for weld preparation and structural modifications. The large diameter also means less disc wear even when the cutting line is extended, increasing cost-effectiveness on an industrial scale.

3.0 mm: High Durability for Powerful Machines

A 230 mm machine generates much more power and torque than 115 mm or 125 mm machines. Therefore, the cutting disc used must be durable enough to withstand this power. The 3.0 mm thickness offers ideal durability, preventing the disc from bending or breaking under lateral stress even when operating at high peripheral speeds. Karbosan's NK (Normal Corundum) abrasive and special binder provide consistent wear and sharpness performance even under such high power.

Balance of Safety and Performance

In professional workshops and construction sites, speed and safety are always priorities. Karbosan manufactures its discs to the highest safety standards. The flat form (Type 41) provides the operator with a good viewing angle during cutting, while the high-quality abrasive grain structure promotes rapid disc cooling, thereby reducing the risk of unnecessary heat buildup and discoloration (burning) in the cut metal.

The Karbosan NK Flat Metal Cutting Disc 230x3.0x22 mm, thanks to its maximum cutting depth, the high durability offered by its 3.0 mm thickness, and its compatibility with large 230 mm angle grinders, is a powerful, efficient, and professional abrasive solution for all sectors requiring thick metal cutting, such as heavy construction, shipbuilding, and industrial manufacturing.
