The advantage of tapered blades is they can eliminate side rubbing that can affect surface finish. But, keep in mind that tapered blades, because they are tapered back from their cutting width, will cut a progressively more narrow groove as they are re-ground when sharpened.
Select desired parallel or tapered blade link in the table below. Or use the filters on the left sidebar to narrow the items that appear at the bottom. Material, coatings, and options will be selected on the next page.
