The choice of a suitable tool for drilling large diameter holes is a key decision, affecting quality, speed and cost of work. The dilemma of diamond and visive holes is one of the most common, which both professionals and masters face. This guide will guide you through the key differences, applications and economic aspects of both technologies, making it easier to make an informed decision.

Understanding the fundamental differences in the design of both types of openings is the key to their proper application. Although the goal is the same – the execution of a precise opening – the way to achieve it is completely different. The cutting edge technology determines in which materials the tool will be efficient and durable and in which it will be quickly destroyed. It is the construction that determines the whole cutting process.
Diamond hole – grinding precision
A diamond hole doesn't cut material in a traditional way. Its working edge is covered with a embankment of synthetic diamonds, sunk in a metal binder using technologies such as vacuum soldering. While working, diamond grains grind and grind material instead of cutting it. This process is extremely precise and generates minimal stresses, which is crucial for processing fragile and hard materials such as porcelain ggres, glass or natural stone. However, it often requires water cooling to prevent overheating and dulling of the embankment.
VIDEO opener — cutting force
A see-through opener, also called a sintered carbide hole, works on a cutting principle. On its perimeter are the teeth made of a very hard sintered carbide (commonly called a vision). These teeth aggressively bite into the material by cutting it out. This design is perfect for building materials with lower hardness, but large volume, such as concrete, brick, hollows or gasobeton. It is often equipped with a leading drill that stabilizes the tool at the start of drilling.
Comparison of drilling efficiency in different materials
The output of the opening is directly related to the material in which we work. Using the wrong tool will not only drastically slow down the work but will almost certainly lead to its destruction or damage to the machined surface. The following comparison clearly shows where each of the technologies reveals its strengths, and the knowledge of what the widget hole serves, and for what the diamond one does, is the basis for effective work.
In the case of ceramic tiles, and especially hard porcelain greek, the diamond hole is unrivalled. Provides clean, smooth edges without risk of cracks and chipping. An attempt to use this material of the visive hole will most likely result in its overheating and destruction of the plate. In turn in cellular concrete, bricks or ceramic hollows, the seed hole will be much faster and more effective. Her aggressive teeth quickly remove the property. The diamond hole can handle the concrete, but the process will be slower and more expensive. In the case of metals, especially steel, none of them is an optimal choice – for this purpose bimetallic hole (HSS).
Durability and viability: which openings are more profitable?
When analysing profitability, you cannot look at the purchase price only. A key indicator is the cost of making one hole, which takes into account both the price of the tool and its viability. The permanence of the hole depends on the quality of its performance, but above all on proper operation – the appropriate speed, pressure and, most importantly, cooling, which is critical especially for diamond tools.
A properly used diamond hole (with water cooling) can make dozens and even hundreds of holes in a very hard gable, maintaining high cut quality. Its service life in dedicated materials is usually much higher than the vision hole. Vision teeth, especially when in contact with harder elements in concrete (e.g. stone), may be crushed or broken. Thus, despite the higher initial price, in professional and serial applications, diamond tools often prove more economical in the long term.
Purchase and operating costs: benchmarking
At first glance, the widget openings are much cheaper than their diamond counterparts. The price difference can be several times, making them an attractive choice for occasional renovation work in building materials. However, a professional comparison of diamond and video openings must take into account the full life cycle of the product and the specificity of the tasks. The cost of operation is not only the price of the tool, but also the working time and quality of finishing.
The investment in a more expensive diamond hole returns quickly with frequent works in the glaze. The speed and precision of drilling and the lack of material losses (broken tiles) generate savings that outweigh the higher purchase cost. In the case of drilling holes under electrical cans in brick or cellular concrete walls, the purchase of a cheap video hole is fully economically justified because the diamond tool will not bring a significant advantage in performance and its cost is disproportionately high.
How to choose the right opening for a specific task?
The final choice of the tool should be driven by three main factors: the type of material being processed, the required quality of finish and the frequency of use. There is no single universal hole for everything. The conscious alignment of technology to the task is a guarantee of success, time savings and money savings. The following tips will help you make the right decision and answer the question what tile hole will be the best and what wall.
- For greek, terracotta, glass, stone:Definitely a diamond hole. It will provide clean edges and will not damage the material. Remember to cool with water to maximize its lifespan.
- For concrete, bricks, hollows, gas concrete:Widiova opener (sintered carbide). It is faster, cheaper and perfectly suited to the specifics of these materials.
- For wood and wood-based materials:Use openings dedicated to wood (so-called springs) or bimetallic openings.
- For steel and color metals:Only bimetallic openings (HSS) that are resistant to high temperature arising during metal cutting.
