Drill flashing internally. Is it broke?

[WheelyCote]

So this us my 2nd drill. The first one was a black n decker and made me nervous because it flashed internally.

I now hace a Bosch. Its quite hard to see the internal workings because the casing is more enclosed...BUT

...the chuck had stuck after a year of livibg in the shed. After wd40 and a but if elbow grease...it realeased tbe stuck drilk bit but me being me opened the chuck wide up and narrow a couple of times (to make sure the wd40 got in there) its stuck sgain.

I turned the drill on to see if that would help and from the different position of using, i can see flashing internalky😫 is it broke or am i being an eeddiott and do they all flash?????

it's usual. Blue flashes from the motor that you can see through te ventilation slots, especially in dark conditions. Putting it in the shed was a bad move as steel parts will rust (especially the chuck springs).

It might be designed so the user can easily change the brushes (by undoing a couple of large plastic screws on the sides), that might help if they are badly worn. If you still have the box and instructions they will explain, and may even include a pair of brushes. They are not expensive.

There is a new generation of drills with brushless motors which I presume don't flash.

I'd carry on using it until it breaks. Presumably it is a mains-powered one and quite big? Medium sized main-powered driills are really good value, so replacing it need not be a big expense.

For light DIY use an 18v cordless combi drill will do most things.

BTW any sort of oil in the chuck will cause grit and dust to stick to it, causing wear and jamming. You might try cleaning it out with white spirit and a small paintbrush (holding it with the chuck pointing slightly downward to prevent anything dripping into the mechanism). I've sometimes immersed a chuck in an eggcup, worked it to and fro, and left the drill hanging up for any residue to drip our and evaporate. You'll be surprised at the gritty dust that comes out. It's possible to fit a new chuck, they are mostly a standard fitting (the retaining screw is left-handed) and may be worthwhile on an expensive tool. They can be very difficult to remove.

Thank you! that's reassuring, I'll look at that.

I need to do a whole house of skirting boards😁 and put up shelves, mirrors etc. Is a standard drill good enough?
I'm petite and the drilling can feel hard going even with a good drill bit.

I've been eyeing up a dewalt in screwfix that's on offer

You'll need masonry bits and a hammer-action drill for walls, but such indoor work only has to make holes big enough for plasplugs. Not difficult unless you have to drill dense concrete.

Is your current drill mains or battery?

Its mains operated PJ

then it should be able to do pretty well everything you want.

Look for its power rating but I won't be surprised if it runs faster and more powerful than the cordless ones.

Are your masonry bits sharp? What colour are they?
