Abrasive Cutting Disc Wapienica PILA W. 300×3.4×30/28 GS20, 300 mm diameter, 3.4 mm thickness, 30/28 mm bore

Abrasive cutting disc Wapienica PILA W. 300×3.4×30/28 GS20 is a high-speed metal cutting wheel designed for use on stationary and portable cut-off machines. With a 300 mm diameter and 3.4 mm cutting thickness, this disc is intended for efficient separation of steel and other ferrous materials. The dual bore (30/28 mm) enables fitment with common flange adapters, providing compatibility with a range of machine spindles. The GS20 designation indicates the abrasive grade and optimized cutting performance for general metalworking tasks.

Advantages

The disc delivers precise, straight cuts with minimal burr due to its thin 3.4 mm cross-section and balanced construction. Its 300 mm diameter provides a larger cutting circumference for faster material removal on thicker sections, while the dual bore ensures flexible mounting options. The abrasive composition and GS20 grade are selected to offer consistent performance and acceptable tool life when used under recommended operating conditions.

Suitable for

• Cutting steel bars, profiles and sheet metal
• Workshop and maintenance cut-off machines
• Construction site metal cutting and fabrication
• Portable angle grinders and bench-mounted cutters with compatible flanges

Key specifications

• Diameter: 300 mm
• Cutting thickness: 3.4 mm
• Bore: dual 30/28 mm for adapter compatibility
• Abrasive grade: GS20
• Intended material: ferrous metals (steel)

How to use

Mount the disc on a compatible machine using the proper flange adapter for the 30/28 mm bore and ensure the mounting surfaces and flanges are clean and undamaged. Verify that the machine's maximum rpm exceeds the disc's rated speed and that the direction of rotation matches the arrow on the disc. Securely tighten the flange according to the machine manufacturer's instructions. During cutting, use steady feed pressure without forcing the disc; allow the abrasive to cut at its designed speed. Maintain personal protective equipment: safety glasses, face shield, gloves and hearing protection. Stop the machine and inspect the disc if vibration, chipping or unusual noises occur.

Usage recommendations

For optimal performance and safety, use the disc only on materials for which it is intended (ferrous metals), avoid side grinding on the cutting edge, and replace the disc if any cracks, severe wear or deformation are detected. Store the discs flat in a dry, temperate environment and follow the machine manufacturer's safety guidelines and local regulations when operating cutting equipment.
