Cutting Disc for Metal KLINGSPOR 350 x 2.5 x 25.4 mm A330 EX (MPN 353326)

The KLINGSPOR cutting disc A330 EX 350 x 2.5 x 25.4 mm is an abrasive wheel engineered for cutting steel and a variety of other metals. With a 350 mm diameter and a thin 2.5 mm kerf, the disc is intended for use on angle grinders or stationary cutting machines that accept a 25.4 mm bore, enabling efficient long straight cuts and partitioning of large metal workpieces. The grain and bonding of the A330 EX provide a balance between cutting speed and service life for heavy-duty cutting tasks in construction, metalworking and fabrication environments.

Advantages

The large 350 mm diameter allows faster linear cutting and reduced operator passes compared with smaller discs, while the 2.5 mm thickness minimises material loss and deformation during cutting. The 25.4 mm bore ensures secure mounting on machines designed for this spindle size. The A330 EX abrasive formulation offers consistent cutting performance on steel and common ferrous metals, and the reinforced construction improves safety and stability during prolonged use.

Suitable for

• Cutting steel beams, plates and profiles on construction sites
• Fabrication shops performing large workpiece separation
• Metalworking shops requiring long, straight through-cuts
• Maintenance operations that involve removal of large metal sections

Key specifications

• Diameter: 350 mm
• Thickness (kerf): 2.5 mm
• Bore (arbor) diameter: 25.4 mm
• Type: Metal cutting disc, abrasive bonded wheel
• Application: Cutting of steel and common ferrous metals

How to use

Select an angle grinder or cutting machine compatible with a 350 mm disc and a 25.4 mm arbor. Mount the disc according to the tool manufacturer's instructions, ensuring the disc is correctly oriented and the clamping flange matches the disc bore. Use appropriate machine guards and secure the workpiece. Operate at the recommended no-load and cutting speeds specified by the machine and the disc safety markings; allow the wheel to reach full speed before engaging the cut, and apply steady, even pressure without forcing the disc. After cutting, let the disc come to a complete stop before setting the tool down.

Usage recommendations

Always use appropriate personal protective equipment: eye protection, hearing protection, gloves and respiratory protection as needed for metal dust. Verify that the disc's maximum rotational speed matches or exceeds the tool's rated speed. Inspect the disc for cracks or damage before each use and replace if any defects are found. Store discs flat in a dry environment away from extremes of temperature and humidity to preserve bonding integrity.
