Friction Cutting Blade

Made of a special fatigue resistant material, this blade is ideal for thin, ferrous sections. It is made of a high-silicon alloy and has a fully hardened tooth with a special tempered back allowing it to be run at speeds up to the 15,000 SFM (4500 m) necessary to achieve the melting point of the ferrous metal to be friction cut. A heavy tooth set further enhances the fast cutting action of these blades. Teeth with "air scoop" action brings oxygen into the kerf to burn up the metal. Cuts materials up to 5/8" (16 mm) thick. Tooth shape is regular. Friction blades are furnished welded in convenient lengths, ready to use. These blades are also furnished in 100`, 250` and 500` (30, 76 and 152 m) coils as listed.
