Applications
Detailed Information
The HSWB1 is a 25mm extra-wide serrated edge blade designed for cutting thick insulation materials that require both maximum cutting depth and a saw-tooth edge profile.
The serrated (saw-tooth) edge grips fibrous materials from first contact, preventing slippage and delivering clean cuts through thick glass wool, rock wool, fibreglass panels and EPS/XPS polystyrene insulation boards.
Manufactured from SK5 high-carbon steel at 106×25×0.50mm dimensions. Non-segmented construction is mandatory for serrated blades. OLFA HSWB-1 compatible. Sold in packs of 3.
