Professional set of Bigstren diamond hole saws for precise drilling into hard and very hard materials – porcelain stoneware, ceramic tiles, natural stone, granite, marble, and concrete. Thanks to vacuum-brazed diamonds, it creates clean holes without chipping and cracks; the set also includes a conical diamond burr for finishing and enlarging holes and a practical case for safe storage.
Clean holes in hard materials
Vacuum-brazed diamonds help achieve fast and even drilling while minimizing chipping and cracks in tiles, porcelain stoneware, stone, and concrete.
Conical diamond burr 2–35 mm
The set includes a conical diamond attachment for precise fine-tuning, edge chamfering, milling, and enlarging holes – ideal for installations where a delicate correction is needed.
Sturdy case for storage and transport
The reinforced aluminum case helps keep the set neatly organized and protected. Durable corners, handle, and latches make it easy to carry safely on site and in the workshop.
The Bigstren diamond hole saw set is designed for situations where standard drill bits are not enough. It enables precise and stable hole-making in hard surfaces during assembly and installations (e.g., cable/pipe feed-throughs, faucets, drains, utilities). The diamonds are vacuum-brazed, which supports an even cut and clean edges.
Main advantages:
- 15 mm high diamond cutting section for longer service life than standard hole saws
- Double layer of diamonds (outer and inner) for higher cutting speed
- Wide diameter range 6–68 mm – one set for multiple types of work
- Can be used dry or wet (water cooling significantly extends service life)
- M14 thread + drill adapter – compatible with an angle grinder and a standard drill
