In what cases and for what purpose is the drill stand (holder) used?

The stand for drills, screwdrivers and hammer drills is a stationary device to which drilling tools are fixed. Most of the holders produced have a restriction on the size of the drill neck, and does not exceed 43-45 mm. Thanks to the use of such devices, absolutely accurate and even drilling of wood materials, metal, plastic products and so on is possible. In addition, the holders absorb vibration, making work easier and more comfortable. You can make a drill stand with your own hands.

What is a holder

If the material to be drilled is very hard, it is extremely difficult to make a straight hole. It is especially difficult to drill at an angle such as 45 °. The drill may slide or break the hole, making it larger. It is for these purposes that drilling stands are used for drill... The holder together with the tool turns into a small machine. The quality of his work depends entirely on the rack.

Before purchasing a holder, you should carefully inspect all moving parts for backlash. You also need to pay attention to the diameter of the neck and the amount of stroke, since the possible drilling depth depends on the latter.

The more massive the drill holder is made, the more reliable it will be. The kit may include a vise to hold the material being processed, or they may be purchased separately. This device not only fixes the workpiece, but also makes the work safer. When choosing a stand, make sure that the base has holes (fasteners) for installing the vise. Most of the holders are compact, so it is convenient to use them even in a small room, for example, in an apartment. The size of the drill bed can be 15x20 cm, and the height is about 50 cm.The weight ranges from 2 to 6 kg. Drilling depth from 6.5 to 7 cm.

Racks are mainly made collapsible, and assembly and disassembly takes only a few minutes. Some models of holders are made in such a way that they can be modified to meet the necessary requirements (increase the drilling depth).

If the stand has a backlash of any part, then tighten the tightening screws or put rubber pads in problem areas. This will immediately improve the quality of hole drilling, even in fragile parts.

What to look for when choosing a drill holder

Before buying a rack, you need to inspect the drill if it has a landing collar. Some models of unstressed instruments may not have it, and without it, mounting in the holder is impossible. The neck is a cylinder several centimeters long. Located near the cartridge. Most models of drills have a standard neck diameter of 4.3 cm. The drill stand is equipped with a special ring in which the tool is fixed with screws.

The next important detail is the base plate. It depends on what material it is made of, what size and weight it is, how well it will absorb vibration. Posts with cast iron bases do a better job than those with aluminum alloy. The plate should have holes or fasteners for installation on a work bench and space for a clamping vise.

The greater the distance between the center column and the drill axis, the larger the material can be machined.

In order for the drill to descend smoothly, the holder is equipped with a spring. As soon as the pressure on the handle is released, it automatically raises the tool. Many stand models have a function that allows you to adjust the drilling depth. This not only helps not to exceed the required immersion depth, but also makes the work easier, especially when you need to make many of the same holes. There must be a scale on the body of the drill stand to determine the immersion level.
