Some floors and coatings are too think or hard for a flat blade to tear up quickly, like wood or thick epoxy. That’s where these heavy steel shanks really shine. Made of ultra-hardened tool steel, these shank blades hold their sharp edges well against even the hardest floors. They can be resharpened with a standard hand grinder and metal wheel to increase removal speed.
These blades are ideal for the removal of wood, stone tile (including thick marble), epoxy floors, really tough thinset and thick rubber.
The 7070-6 straight shank is 6″ wide, and commonly used to tear up wood flooring and 6×6 or 12×12 ceramic tile squares, allowing you to come back with a larger blade for cleanup. The 7070-6 measures 4″ deep x 6″ wide x .500″ thick.
Additional sizes of this blade type:
(Depth x Width x Thickness)
7070-2 – 4″ x 2″ x .500″
7070-3 – 4″ x 3″ x .500″
7070-4 – 4″ x 4″ x .500″
7070-6 – 4″ x 6″ x .500″
These straight shanks fit on all of National’s Ride-on Scrapers.
