Drill bits

The correct choice of diamond drill bits, core drills and widia drill bits for drilling marble, granite, concrete and porcelain stoneware without chipping and obtaining precise holes is crucial. Here are some important points to consider when buying the right drill and diamond drill bits:

Electroplated drills are ideal for drilling marble, stone and travertine. Electroplated tools are coated with diamond particles through an electroplating process. The diamond coating allows them to be highly durable and to drill marble smoothly and quickly with dry or water, both with a drill and CNC machines.

The sintered diamond segment or diamond core drills for granite are used to drill granite, quartz or quartzite. These drills are equipped with sintered diamond segments welded onto a steel body. How to drill granite: diamond drills for drilling granite offer excellent cutting capacity and abrasion resistance when drilling granite.

Diamond drills for porcelain stoneware are useful for drilling porcelain tiles or slabs: Porcelain stoneware is a dense and resistant ceramic material. For drilling stoneware, brazed or sintered diamond drills are recommended. These drills are characterised by diamond segments anchored to the drill bit body by brazing the diamond. Brazing provides greater resistance to heat and abrasion, enabling effective and precise holes to be made in porcelain stoneware.

Widia drill bits for drilling marble, granite and stone are made with a sharpened widia (carbide) insert. These drill bits are made with tungsten carbide inserts that also offer greater strength and durability when drilling into concrete.

How to drill marble without breaking it: For drill bits and diamond cutters, remember to use water when drilling to reduce overheating and preserve the quality of the diamond drill bits. Carefully follow the manufacturer's instructions for safe and effective use, respect the rotation and feed parameters to drill high quality holes without chipping on marble, granite, concrete stone and porcelain stoneware.
