Hi all! I will tell you how to make a very convenient key for the chuck of your drill, drilling machine or hammer drill. The original key that comes with the kit is extremely inconvenient. It is very difficult to tighten the drills and when changing the drilling tool frequently, your fingers begin to hurt. This problem can be easily solved in a short period of time if you make your own convenient key for the cartridge.
We try to securely tighten the drill in the chuck using the included key.
Due to the small lever, it is very difficult to create the proper force, and therefore to securely secure the tool. As a result, due to excessive force, unpleasant pain appears in the hand.
Making a convenient key
It is necessary to cut off the head of the original key, but not at the root, but at a distance of approximately 5-7 mm. To do this, use a marker to mark the cut location.
Holding the key with pliers, we saw off the head with a grinder. If you have a vice, use it, as this method is extremely dangerous.
Next, you will need a spanner wrench, into the hole of which the sawn-off head can be inserted as close as possible. I took 8, I don’t need it that much, especially since the second half of it will remain working.
We insert one into the other.
We fix it with arc welding.
We beat the scale with a hammer after welding. We polish it to a shine with a grinding wheel on a grinder.
Our convenient key is ready.
We test it: it tightens the cartridge very well, it’s just a song!
It's a shame that I suffered for a long time with a regular key. I recommend that you do the same.
As a result of the longer lever, you can easily create a good tightening force without unnecessary strain on yourself. Enjoy it friends! Very comfortably!
