Nothing Cuts Like A Warthog The Warthog is a carbide-tipped, circular saw blade designed especially for fire department venting operations. Be it floors, walls or roofs, the Warthog's aggressive tooth design cuts through roofing materials, wood flooring and siding like a hot knife through butter. The aggressive tooth design of the Warthog ventilation blade easily and quickly cuts through roofing materials, wood flooring and siding. Heavy duty construction helps prevent tip loss, the major problem with standard carbide tip saw blades. Each oversized carbide tip is mounted to the blade by a special process. This cushions the tip mounting and makes this blade the most durable (and probably the last) ventilation saw blade you will ever buy. Does your standard carbide tip blade offer you the same advantages as the Warthog ventilation blade?
