Professional Bigstren diamond core drill bit set for precise drilling in porcelain stoneware, ceramics, stone, granite, marble and concrete. Vacuum-brazed diamonds, a double diamond layer and a 15 mm working height contribute to fast cutting, clean edges and a long service life.
Precise drilling in hard materials
The diamond core drill bits are suitable for drilling in porcelain stoneware, ceramics, natural stone, granite, marble and concrete. Vacuum-brazed diamonds help achieve clean and precise holes.
Wide range of diameters
The set contains 11 core drill bits with diameters from 6 to 68 mm and a conical diamond burr from 2–35 mm. It provides a practical solution for installation, assembly and renovation work.
Durable case for safe transport
The reinforced aluminium case with a handle, metal fasteners and protected corners keeps the tools neatly organised and protects them during transport.
The Bigstren diamond core drill bit set is designed for demanding work in hard and very hard materials. It enables precise holes to be made without unwanted chipping of the surface. Thanks to the M14 thread, it can be used with an angle grinder, while the included adapter also enables use with a standard drill.
Vacuum-brazed diamonds and a double diamond layer on the outer and inner sides support efficient and even drilling. The core drill bits can be used dry or wet; water cooling helps extend their service life. Selected components with cooling wax or ventilation holes help reduce overheating during work.
The set includes:
- 11 diamond core drill bits with diameters of 6, 8, 10, 12, 20, 25, 28, 35, 45, 50 and 68 mm,
- a 2–35 mm conical diamond burr for modifying and enlarging holes,
