Applications
Detailed Information
The LWB serrated edge blade is a specialised 18mm utility blade designed for cutting fibrous, porous and insulation materials that would jam or tear with a standard smooth edge.
The saw-tooth (serrated) edge profile grips the material from first contact, preventing slippage and delivering clean cuts through glass wool, rock wool, fibreglass panels, EPS and XPS polystyrene insulation boards.
Manufactured from SK5 high-carbon steel at 100×18×0.50mm dimensions. Non-segmented construction is essential for serrated blades as score lines would compromise the integrity of the saw-tooth pattern.
OLFA LWB-3B compatible. Sold in packs of 3.
