High precision; clean, smooth cuts; cutting depths ranging from 43mm to 50mm, depending on hole size. Solid materials, high hardness, fast cutting speed, impact resistance, high temperature resistance; sharp gear, cutting resistance, low consumption, 50% longer life, corrosion resistance, and heat resistance are used. Moreover, vacuum brazed diamond hole saw offers greater rigidity, making it ideal for users looking to cut metals quickly and efficiently.The hardness of the product is a result of easy-to-cut toothed blades, sharp gears, anti-cutting low consumption and high temperature quenching. It has a sharp gear, a small cutting resistance, and a long service life. Due to the sharper cutting edge, the cutting force is reduced, the drilling rate is reduced, and the hole wall is improved. High-quality diamond particles help dissipate heat and remove dust, and vacuum brazing technology minimizes breakage and maximizes service life.

A hex adapter allows these bits to be used in standard drill chucks. If you do want to use them on a drill, it is best to run it at full speed on a corded drill; cordless drills tend to run slowly and can reduce your drilling speed and drill life.
