48 tooth; 2.2mm kerf; 20mm arbor; 5 deg hook angle; ATB. Cross-cut blade for smooth cuts in veneered plywood, sheet goods, melamine, and hard and soft woods. Oversized 20mm arbor enables more secure fastening of the blade to the saw, reducing vibration for more precise cutting. Thin kerfed blades meet less resistance, for more efficient cutting, and produce less material waste
