Product Introduction

This product is made from forged bearing steel trimming scrap, which undergoes heat treatment, crushing, and further heat treatment followed by screening. This type of steel grit is specially designed for cutting granite stone, featuring excellent angularity, uniform particle size, and superior wear resistance. Proven through years of use by numerous stone manufacturers, it enables faster stone sawing speeds and produces flatter sawn stone surfaces.
