The drill collar – the ideal tool for do-it-yourselfers

The ideal tool for do-it-yourselfers is the drill collar. In many situations where you need to drill a circular hole, it will help you reliably as an attachment for a drill, a hammer drill, or a cordless screwdriver. No matter whether in the sanitary area, with furniture or on walls, where a perfect hole for a socket or a pipe must be created. A distinction must be made here between the drill bit for DIYers, the hole saw and the drill bit.

As an experienced do-it-yourselfer, you are certainly familiar with situations like these: you want to help build your own house and help the professionals. For example, many pipes have to be laid and led through walls indoors and outdoors. Or in each room numerous sockets are to be attached.
Or you may have to drill a circular opening into the wall of a room in your apartment in order to lead cables from the computer to the adjacent room in your home office. In the kitchen, you need a hole to place the drain pipe through the wall unit in the base unit of the sink. In all these and many other cases, the drill collar is the only tool for do-it-yourselfers with which you can carry out an optimal solution like a professional. The advantage for the do-it-yourselfer is obvious: they drill and cut with the drill bit in one operation and have completed their task quickly.
Different materials require different tools

Depending on the situation, do-it-yourselfers need a Cutting device that perfectly cuts the desired size of the hole from the wall. For this reason, there are a large number of drill rings of different sizes. If you are often faced with the problem of having to make a perfect hole in a wall, you should choose a set. This means you are well equipped for many situations.

In addition to the desired size of the hole, the building material through which you have to cut is of primary importance. There are walls made of hard material such as bricks, concrete and tiles as well as of soft material such as wood, for example chipboard or plywood boards, OSB boards or gypsum in the form of plasterboard or stucco.

Generally it can be said that do-it-yourselfers choose the drill bit depending on the situation for soft material, for usual masonry of hard material like brick the drill bits and for particularly hard material, thus concrete, stone and tiles the diamond drill bits. For wood, the do-it-yourselfer uses hole saws.
In use, all these tools are the same, because all you have to do is place them on your drill as an attachment and then hold them on the wall.

Safety first

In principle – as always – you make a hole in the wall with the drill. This time it’ll just be a big one.

As with any use with a drill, as a do-it-yourselfer you must use the tool safely. First check whether there are any electrical cables running through the wall. Then make sure that you as a do-it-yourselfer have fastened the cutting equipment.

The next step is to consider whether the material is normal, soft or very hard. In the latter case you should definitely remember to drill wet. This is because materials such as stone, concrete or tiles result in an especially strong Friction.

The manufacturers have come up with a clever solution. There’s a sponge for Bohrkranz to stick in. This is first kept in water until it has absorbed all of its water and can then release the water again during the drilling process. A simple but effective idea to achieve the desired cooling effect when wet drilling.

For all other materials, the normal room air is sufficient for cooling to prevent the drill from overheating.
When wet drilling, you have to pay double attention to safety. On the one hand, as a do-it-yourselfer you must be aware that water escapes during drilling. Therefore, be careful not to leave any cables exposed or to allow splashing water to enter an electrical outlet. It goes without saying that no current may flow over the ground.

On the other hand, every drilling operation makes dirt. As a do-it-yourselfer, you run the risk of being hit by small flying wood splinters or pieces of wood from the wall or tiles. It is therefore essential that you wear protective goggles, a dust mask and suitable work gloves. If you work as a do-it-yourselfer on your own construction site, work shoes and a helmet are of course included.

Rent instead of buy

Whether you want to make the investment as a do-it-yourselfer or not depends on how often you have to cut holes perfectly in the wall or cabinet. In addition, your personal budget plays a role and potential storage space.

If you live in a small apartment without a cellar, you have only limited capacity to store things. Ask your acquaintances if someone would lend you a drill string as a do-it-yourselfer. If this is not possible, inform yourself in a DIY store in your residential area whether you can use the tool against a small rental fee there.

For all other do-it-yourself enthusiasts, however, the following applies: A drill bit is part of the basic equipment, the additional drill bit hardly takes up any space and is an irreplaceable tool for cutting perfect holes.

A variety of models are available on the market

If you are a do-it-yourselfer and want to buy a drill collar, you are spoilt for choice between different models. The range extends from attachments for professionals to cheaper models for occasional use.
As already described, you will need different attachments for your drill depending on the situation. For particularly hard cases such as concrete, tiles, stoneware or natural stone, impact drill bits or diamond drill bits are also available at the DIY store or online shop. Otherwise, a normal drill collar or a drill bit is sufficient.

Do-it-yourselfers make a good choice with a set of drill collar and additives

If you are working with such a tool for the first time, the purchase of a set is highly recommended. In addition to the matching drill bit, it also contains the necessary additional equipment such as a centring drill and adapter.

With the adapter, you can be sure that your newly purchased cutting tool will fit on your home drill and hold securely during the drilling process.

You will also need a small or larger wreath if you need to drill several holes of different sizes. As a do-it-yourselfer, you will always be well equipped for all kinds of work, even in the future. do not have to invest time again in the search for a new suitable cutting tool.
