Modern glazing poses increasing challenges to performers, mainly due to hard and fragile materials such as porcelain ggress. The precise construction of holes for sanitary or electrical installations has become a key element of professional finishing. In this context, the diamond hole is an indispensable tool. It is thanks to it that it is possible to cut clean and fast without the risk of damaging expensive tiles. This article is a comprehensive guide that will explain how to choose the right tool, which techniques to use and how to take care of the equipment to make working with a diamond hole in glazing effective and seamless.

Selection of a diamond hole for tiles: what to pay attention to?

The choice of the right diamond hole is crucial for the success of the entire venture. The decision should be dictated primarily by the type of machined material. Other tools will work in the case of soft ceramic tiles, and others will be necessary for hard grits. Pay attention to the type of diamond embankment – those vacuum-filled (vacuum brazed) are more durable and better suited to the toughest materials. The mounting system (e.g. M14 thread for angle grinders or hexagon handle for drills) and the use of the opening – for dry operation (with cooling wax) or wet operation is also important.

Drilling techniques in ceramic and ggres tiles

Effective and safe drilling in plates requires knowledge of appropriate techniques that minimise the risk of cracking the material. The key element is to start working at an angle of about 30-45 degrees. This allows you to create an initial incision that stabilizes the opening and prevents it from "slipping" on the smooth surface of the plate. After completion of the groove, proceed gradually to a perpendicular position, making gentle circular movements. Such movement facilitates removal of the material and improves cooling, which is extremely important for the durability of the diamond segment and the quality of the hole itself.

Wet vs dry drilling: what to choose?

The decision between wet drilling and dry drilling depends on the equipment and working conditions. Wet drilling, using a constant supply of water, is preferred due to excellent cooling, which significantly prolongs the life of the opening and eliminates dust. This is the cleanest and safest method for the tool. In turn dry drilling is faster and does not require additional water feeding equipment. However, only holes for this purpose, often equipped with special wax, which melts under the influence of temperature, cooling and lubrication of the cutting edge, should be used. Dry work requires regular breaks to cool the tool.

Drilling of holes under installations: sockets, pipes

One of the most common applications of openings is the making of transitions for water and sewage pipes, electric cables or mounting of flush-mounting cans. The precise execution of these holes is the card of each glazer. The key is to accurately measure and mark the central opening point. For standard electric cans, 68 mm holes are most commonly used. The formation of holes in ggres plates under installations requires special care due to their hardness and brittleness. The use of the guide for drilling or starting work at an angle is absolutely necessary here to avoid costly mistakes.

Glazier tricks: clean and precise holes

Experienced glazers have their proven methods of making a hole in the plate to make it perfectly smooth and without scratches. In addition to this technique of starting at an angle, it is important to control the speed of the device – too high rotations can overheat and destroy the diamond embankment. It is also important to avoid excessive pressure; the opening should work under its own weight. Using templates or special suction cups with a guide is another way to stabilize the tool and guarantee perfect precision.

Here are some key tips to help you get the best results:

• Always start drilling at an angle to create leading grooves.
• Use moderate speed and avoid excessive pressure.
• Make light orbital movements to aid cooling and removal.
• Regularly cool the hole, especially when working dry, making short breaks.
• If possible, use the guide to drill for maximum stability and precision.

Purification and maintenance of openings: extension of service life

Diamond openings are an investment, so it is worth taking care of. After each work, the diamond segment should be thoroughly cleaned with residual material and possible wax. You can use a soft brush for that. It is important to keep the tools in a dry place, preventing corrosion of the steel body. Regularly check the state of the diamond embankment – if it is "advised" or smoothed, it can be gently "accelerated" by making several holes in the abrasive material, like a block of cellular concrete. Such maintenance will ensure that the opening will serve long and efficiently.
