Worx 20V drill issue

I just bought a Worx cordless20v 386.5 drill. There are lots of sparks visible from the brushes - is this normal? Of greater concern is that when one lets go of the trigger the drill comes to an instant and quite violent stop. Several large clunks can be heard and felt. This is the very opposite of smooth and feels very wrong. I have two other non Worx similar drills and they both stop smoothly, as do those I have looked at on Youtube. Please advise.

sounds normal....they are not quality items.....

even my Japanese made Hitachi drill spark a little when viewed thru the cooling slots....and is a tad noisy on shut down.....remember there's a lot of weight to slow down quickly....personally I prefer drill to slow down and stop the old way, in it's own time....I find the weight of the bigger voltage machines quite wearing after a days use....torque reaction...

the clunk is all the gears and other rotating bits n bobs coming to a halt....cheaper equipment means lower tolerances i.e. bigger gaps....

providing it's not noisy when working I'd not bother to much BUT u could take it back to where u bought it from and compare with another machine of the same type...

I bought a couple of cheap and nasties from lidil to get me outta a hole when on a job....

surprisingly they worked and lasted well...but with similar prob u describe.....

with this kinda gear u really get what ya pay for.....buy cheap buy twice I'm afraid.....

The coming to an abrupt stop is the brake circuitry working perhaps?

Abrupt stop is indeed the brake which should stop the chuck almost instantly, my DW ones do. I get some sparks but not excessive, maybe just teh brushes bedding in.

Weight wise my Li-ion 18V compact brushless combi is lighter than the old 12V yet more powerful and solid.

Releasing the trigger gently will usually bring the drill to a more gentle stop

Throw it back and pay the Makita (or other decent brand) brushless drill tax. Twice the price but considerably smoother all round and longer battery life. Looks like the steam is running out of the buy a cheap one and use it till it breaks idea. The good brands have got much better without being significantly more expensive.

I've been happy with Makita for years and found the switch from NiCad to Li-ion a big jump in performance. Being able to use the same batteries on several tools is big attraction. My 18 V Makita has almost scary torque levels. I got my Makita stuff from Fastfix who do decent prices and fast service. There are other good outlets. Biggest problem with Makita is the huge number of model type numbers. Need bit of analysis to be sure that what you get is what you expect. Screwfix offers can be good but essential to check the numbers as you rarely get a good price on the real beasts. If you do swop for Makita make sure its LXT batteries.

OT but the Makita dual battery hedge trimmers and streamers are total beasts!

Definitely turning into a cord cutter. Only planer and circular saw are still wired and that will almost certainly change next time I have a proper project.
