• <p>Here you will find our extensive collection of micro drills, packed in a transparent, plastic box. We have boxes with 10 pieces only of 1 diameter (for example 0.8 mm) as well as combi sets (for example 0.4 - 1.0 mm). The shaft of the drills in these sets is always 3.175 mm and they are always provided with a spacer (ring) in a random color.</p>
  • <p>A <strong>concrete drill</strong> is used to drill holes in materials such as stone, masonry and concrete. Traditional drills are too fragile for this purpose. <strong>Concrete drills</strong> are made of durable, harder material that can withstand the force. These drills are usually equipped with an SDS(plus) system. An ordinary drill is fixed by the chuck of a drilling machine, a drill with an SDS(plus) shaft has a recess on both sides through which it is clicked into the drill, which can only be done in 1 way. The drill is immediately secured. This way it will not move during drilling. The concrete drills we sell are available in diameters 6 to 25 mm with lengths of 110 to 400 mm.<br />##</p> <h2>How to drill into concrete with a impact drill</h2> <p>There are several steps to follow when drilling into concrete. These are:</p> <p><strong>Marking the spot<br /></strong>You should start by marking the location where you are going to drill a hole. In addition, you need to think about how deep the hole should be. You can measure this with the help of a stop bar. You can also determine the depth by wrapping masking tape around the drill.</p> <p><strong>Prepare the drill<br /></strong>Wear your safety glasses. Next, you need to insert the right size concrete drill into your impact drill. Make sure it is properly locked to prevent slipping while drilling.</p> <p><strong>Put yourself in the right position<br /></strong>Hold the drill firmly and place your feet shoulder-width apart. To get more control, you can use the extra handle. If there is no extra handle, you should hold the hammer drill in the same way as a handgun. Care should be taken to keep the drill perpendicular to the concrete. The hammer action will cause some recoil.</p> <p><strong>Drill a guide hole<br /></strong>When the drill is on a slower setting, make the guide hole. If the drill has only one speed, you can use it in short bursts until the guide hole is about 1 cm deep.</p> <p><strong>Drill the desired hole<br /></strong>Hold the drill firmly but lightly. This will allow you to tackle any rock piles or hard material in the concrete. It is easy to lose control of the drill when drilling through concrete. With the guide hole in place, you can easily control the drill. As you become more and more confident, you can now increase the rotation speed until you have made the complete hole.</p> <p><strong>Remove debris/grit<br /></strong>It is advisable to pull the drill back after every 10 seconds to remove the debris from the hole. This will allow the drill to continue working on the hard concrete without being bothered by the grit.</p>
  • <p>Hand drills are ideal for drilling small holes in soft metals such as aluminum, but they are also perfect for making holes in cork, wood, plastic and rubber. Due to the size of the holes that are made, drilling requires little force and the holes can be made with extreme precision.##</p> <h2>Use hand drills in model building</h2> <p>Model building is a fantastic hobby. Models of airplanes, cars and ships are available in almost every toy store. They can be glued together and then painted to look exactly like the original. But there are many more forms of model building. Think of trains, for example, where enthusiastic hobbyists manage to build hefty dioramas complete with cities, mountains, waterways and of course one or more train stations with an astonishing resemblance by making clever use of wood, cardboard and plaster. Of course including moving trains that prefer to run together in complex schedules. Yet another form of model building is the reconstruction of specific aircraft, cars, ships and equipment on the basis of original construction drawings and photos. From scratch, closely resembling models are made of the original. With each of these forms of model building, a lot of work is done with soft materials and there is a need to make holes in these materials. For example, for the passage of thin electrical wire cables to illuminate objects. When holes have to be drilled in these materials, modellers prefer to use hand drills rather than cordless drills or electric drills, because hand drills provide an optimal feeling and therefore allow very precise work.</p> <h2>Hand drills when making jewelry</h2> <p>But also makers of jewelry are avid users of <strong>hand drills</strong>. After all, precious metals such as gold, silver and platinum do not oxidize, but they are also relatively soft materials in which holes sometimes have to be drilled, for example to be able to connect them together. Hand drills are ideal for this, as they offer maximum control. In addition, by drilling manually, you can very precisely determine the force with which you drill. Not all jewelry is made of precious metals. Especially in the corner of people who make jewelry as a hobby, you will find plenty of fanatic makers of jewelry who use modern plastics, such as epoxy resin. By pouring a colored epoxy resin into a mold and letting it harden, you can make the most beautiful jewelry. You can use this epoxy resin jewelry as a charm in a bracelet, necklace or earrings by making holes in it with a <strong>hand drill</strong>. On this page you will find various excellent hand drills, possibly equipped with the corresponding drills. This way you can go in all directions as a model builder or maker of jewelry.</p>
