【Brazed Technology & Firm & Sharp】 brazed dry diamond core hole saws are made of diamond integral steel, which is firm and durable. High anti-corrosion brazing process is adopted on the surface, and the thickened diamond coating on the top provides excellent cutting strength for high-precision and smooth cutting, and the drilling is stable and fast.
【Dry & Wet Dual Purpose Design】All brazed hole saws are treated by special high-temperature resistant process. Even without water as lubricant, they can still withstand the huge heat generated by the hole saw when it rotates at high speed. Of course, you can also use water as an additional coolant to extend the service life of the hole saw.
