Whiteside 90800101 Combination Blade. 8" Diameter. 40 Teeth. 5/8" Bore. The standard multi-purpose blade for a wide range of materials, including softwood, hardwood, plywood, and particle board. The large gullet at the raker tooth, along with the 15° hook angle, provides easy feeding for ripping style cuts, while the close grouping of the other four ATB teeth produces a lighter chip load for crosscutting and finish work. These blades offer a great combination of versatility and efficiency.
