Cutting depths range from 43mm to 50mm, based on hole size, with high precision and clean, smooth cuts. High hardness, fast cutting speed, high temperature resistance, sharp gears, cutting resistance, low consumption, 50% longer life, corrosion resistance, heat resistance; strong material, high hardness, fast cutting speed, impact resistance, high temperature resistance. Diamond hole saws with vacuum brazing provide increased rigidity, making them ideal for cutting metal efficiently and quickly.Due to easy cutting of toothed blades, sharp gears, low consumption of cutting resistance, and high temperature quenching, the product's hardness is a result of these factors. The gears are sharp, the cutting resistance is small, and the service life is long. The sharper cutting edge reduces cutting force, drilling rate, and improves the hole wall. Vacuum brazing technology minimizes breakage and maximizes service life by displacing heat and removing dust, while diamond particles dissipate heat and remove dust. In order to maximize convenience and cost savings, external braze coatings up to 5/8" (15 mm) allow for better edge finishes after drilling.

U-shaped flute design, longer service life, fast and smooth drilling. These hole saw bits feature a universal thread for angle grinders. Standard drill chucks can be used with M14 adapters. Using them on a drill requires a corded drill; cordless drills tend to run slowly, reducing drilling speed and bit life. M14 accessories fit directly to angle grinders of 115mm and 125mm diameter. They can be run at speeds above 10,000 rpm dry.
