Laser welding technology ensuresexceptional wear resistance and high-temperature stability for thediamond core drill bit, making it ideal for various drillingconditions, even in high-temperature environments. It's less proneto tooth loss and weld detachment, resulting in increaseddurability.

In dry-cutting mode, you'll experienceunmatched cutting and debris removal speeds, boosting workefficiency. In wet-cutting mode, water cooling and lubricationreduce drill bit wear, prolonging its lifespan and minimizingdust.

Insert the pilot bit into the adapter,ensuring the drill's tilt angle matches the adapter bolt holeangle, and tighten. Be sure to insert the adapter into the coredrill bit and secure it. The pilot bit must be centered on thedrill bit, with a center deviation of no more than 1millimeter.

The wet/dry drill core bit ensures cleanand precise holes in tough materials like red bricks, concrete,foam bricks, and more. It comes with a diamond saw blade, allowingyou to cut various materials with precision, smoothness, andefficiency.
