Concrete is one of the primary materials used for building purposes in the majority of urban projects. But concrete needs proper adjustments to shape them and arrange them for constructions and building purposes. Concrete is required for various construction purposes, such as structuring slabs, walls, grounding, footings, etc. But for this, concrete cutting and drilling become necessary to be moulded into shapes for construction. Concrete cutting involves cutting or sawing the concrete.
Drilling is a part of concrete cutting itself, but it also includes controlled sawing and concrete removal. To put it precisely, concrete drilling creates reinforced circular holes for construction.
Which Instruments Are Used For Concrete Cutting and Drilling?
Concrete cutting and drilling require skilled workers to handle the specific tools to manage the challenging task. Usually, machines like various cutting saws are used to cut into concrete or bricks and tiles and other similar rigid construction materials. The tool list for concrete cutting comprises the floor, rock, chain, and wet saw. Cutting saws are also used to mould and shape concrete into floors, stairs, decorative counterparts of building etc. These particular types of saws can cut into concrete and asphalt with sharp unmistakable accuracy and precision.
Few types of cutting saws used in construction are Diamond Saw which is preferable for quick, accurate cuts. For decorative concrete cuts, concrete wall saw is used for cutting into walls, and flat sawing is used from level surfaces like floors etc. Wire sawing is for cutting edges with precision. These are all hand-held saws powered with a two-stroke gas or engine that come along with a hydraulic power unit, an electric motor or an air compressor, and their super-sharp diamond or abrasive blades help to achieve the sharp, precise cuts.
Previously Jackhammers used to be used for concrete cutting and breaking up, but this was a messy process that produced a lot of dust and debris. Modern saws are much more precise and accurate at handling concrete cutting tasks leaving smooth, visually pleasing concrete and asphalt surfaces.
Durability is often a big obstacle for concrete drilling, but you may hang an art piece if you want to decorate your home. In such cases, concrete drilling becomes an essential need. Concrete drilling requires heavy-duty drilling machines like a hammer drill, core drills or diamond core drills. Core drills can expose spaces by drilling into rocky concrete chambers.
They can also be used to remove the concrete cores and to cut junction extensions.
Hammer drills are the most powerful and most durable drills; unlike standard rotary drills, they work with a hammering action instead of simply rotating. This hammering helps to grind the concrete faster, while the constant rotating motion helps dig the hole.
Process of Concrete Cutting and Drilling
Concrete cutting can be a simple process if the right people handle the appropriate tools for specific types of cutting. The wrong machine in the wrong hands or used in the bad areas can be a waste of time and money and hazardous. This is why workers must have a basic, intermediate understanding of the concrete cutting process to complete the job without hassle. The execution method can be different, but the basic steps involved in concrete cutting are –
It is essential to have a proper layout of the area where concrete cutting would be performed. If the depth of concrete to be cut is more profound than 4 inches, use an appropriate industrial-grade sawing machine. It is important to proceed carefully with lower RPMs first and cutting to the proper depth. For more precise cutting, use chalk guidelines, and most importantly, understand the type of concrete before cutting so you know its strength and the correct saw to use.
Drilling may be a bit more complicated because of concrete hardness and density and obstacles of embedded stones. For this challenging task, hammer drills are the most suitable machine for all kinds of wall drilling. Understand the proper depth for drilling before you start and mark the position with chalk. Make a guide hole with your drill on a lower rpm speed first; this will make the process easier.
Wear protective goggles for concrete cutting and drilling to protect your eyes from dust or stray sparks.
