One, How to drill holes in marble without cracking
Using the appropriate drilling tools on marble will not cause cracking. Can marble be drilled with a hammer drill? If so, drilling with a hammer drill will likely cause cracking.
To prevent cracking, large-sized holes in marble are typically created using two types of drill bits: one made of diamond, suitable for marble, tiles, glass, etc., which can be used with a standard drill; and another made of hard alloy, also suitable for marble, tiles, and glass. When drilling, it is important to apply even pressure and use water cooling to prevent the drill bit from overheating and failing.
However, it is important to note that when drilling, you should add water continuously and avoid dry drilling, as this will quickly damage the drill bit. The key is to control the force; excessive impact is best applied initially by lightly tapping into the wall with a steel nail to create a mark, followed by slow, controlled impacts, which reduces the risk of damaging the drill bit or causing it to deflect due to excessive impact. Many impact drills have a slow-impact setting.
Two. What tools are best for drilling holes in marble?
1、Utilize a professional stone quarrying machine, which is relatively inexpensive. These machines produce elliptical-shaped openings. The efficiency is moderate, and the quality is good.
2. Manually remove it, create a hole, and then use a corner-shaped tool to scrape away the remaining material. This method is inefficient, produces low-quality results, and requires more manual labor.
3、Spray guns are expensive, but they have a wide range of applications. They come in various open shapes, such as square, round, and oval. They offer good quality and efficiency, but at a higher cost.
