CT 12pcs M10 Thread Brazed Diamond Hole Opener Core Drill Bit

12HoleDrill

Dry and Wet Use: All our diamond hole saws kits undergo a special high-temperature resistant process. The internal wax-filled vacuum brazing technology can withstand the intense heat generated by the high-speed rotation of the hole saws, even without using water as a lubricant.

Brazing Process, Sturdy and Sharp : Our brazed diamond core hole saws kit is made from solid steel with diamonds, making it sturdy. The surface uses a high anti-corrosion brazing process with a thickened diamond coating at the top for cutting strength, high precision, smooth drilling, and fast stability.

Wide Application : The diamond drill bits are suitable for easy dry drilling on hard ceramic tiles, ceramics, bathroom tiles, granite and marble, bricks, concrete, glass and hard PP. The special design of the spiral groove at the top of the drill bit helps to discharge chips.

Convenient Storage: Our diamond brazed core drill bits come with a portable carrying case. The interior uses an EVA casting design that firmly secures the drill bits in the box to avoid damage from shaking.

12-Piece Set: This M10 Brazed Hole Opener Set includes 12 pieces of premium quality diamond drill bits that are suitable for both professional use in construction or DIY home projects requiring drilling on various materials.
