The professional BIGSTREN diamond hole saw set is designed for precise drilling in porcelain stoneware, ceramic, stone, granite, marble, and concrete. Thanks to vacuum-brazed diamonds and a double-layer grit, it delivers a fast, chip-free cut and long service life. Range 6–68 mm, thread M14, and an included drill adapter ensure broad compatibility. The set also includes a conical diamond reamer 2–50 mm for corrections and enlarging holes, plus a durable aluminum case for safe storage.
Fast, clean cuts thanks to a double diamond layer
Vacuum-brazed diamonds with a dual-surface coating ensure rapid drilling without edge chipping, even in hard materials such as porcelain stoneware or granite.
Wide diameter range and 2–50 mm conical reamer
Five core bits 6, 8, 10, 35, and 68 mm cover most installation tasks. The conical reamer enables precise widening and fine-tuning of holes.
Sturdy aluminum case for safe storage
Lightweight yet robust case with foam insert protects the tools during transport and keeps the workspace organized.
The BIGSTREN set is ideal for plumbers, tilers, and demanding DIYers. Vacuum-brazed diamonds and a 15 mm high diamond working layer provide clean edges without cracks, high speed, and cutting stability. Smaller diameters feature integrated cooling wax, while larger ones include ventilation holes to reduce overheating and extend tool life.
With the M14 thread, the bits can be used on an angle grinder; with the included adapter, also on a standard drill. The 2–50 mm conical reamer makes it easy to chamfer edges, calibrate, and precisely enlarge openings. Everything is neatly stored in a durable aluminum carry case with foam insert for safe transport.
