This saw blade is Laser cut plate and Rockwell 46 hardened steel.  Teeth are large and may be sharpened and made with more exotic & expensive materials and more precision honed. They are made of the finest materials available for their designated purpose.  Typically used with circular saws, table saws, and chop saws.

The body is precision manufactured for sound dampening that also reduces vibration and makes a blade run smoother

Saw blades are graded in 4 categories: Economy, Normal, Premium, & Industrial with industrial being the best made. Normal grade is generally used in the Pallet industry. It cuts faster with less power (heat).  Industrial blades cut smoother have the bests quality of materials, last longer and will take more abuse (heat). The steel is thicker, of better quality more precisely made
