Electric drills are the most widely used power tools in the home. It is included not only in professionals, but also in almost all household equipment. Without a drill, you can not hang heavy objects on walls, curtain brackets, heavy paintings and some furniture. Who quite often works in the drill, perhaps soon he will meet the fact that he needs to replace the chuck. Over time, it can wear out or be damaged. And without the chuck, the drill is just an unnecessary piece of technical equipment.
Types of chucks
*Quick Release -Tighten by hand using the locking mechanism.
* Toothed tightening by handle by a system of gear attachment to toothed comb.
According to the spindle mounting system, the chuck is divided into:
*Self–locking cones – These are found in professional tools as well as vertical stand drills. The removal of this type of chuck is very quick and easy.
* Threaded cones – common in most cordless and electrical types, with more common attachments with thread sizes of 3/8 inch, 1/2 inch and 5/8 inch.
Replacing or purchasing a new drill
Remember that each chuck is strongly tightened in principle and requires considerable force to loosen.We can also help by applying a screw-in disconnect. Next, place a side wrench on the spindle (each device may differ in size, but it is usually 17〜19mm), place a long 8〜10mm L-shaped inbus wrench with the chadrill on the ground, support one foot with the wrench, and push the impact force indus towards the ground with the other foot. Inbus must be clamped at a washer angle of 50-60 degrees, do not forget that there is a thread on the left, so we allow from left to right! Disassembly is easy, if you can turn the head, replace the existing part with a new one and gently tighten it again with a wrench and inbus.
Some hand tools do not have an accessible spindle to attach the key.In that case, it is necessary to entrust the entire operation to professional services.
