SDS Drills. Advice please

nick 56

My old drill was struggling so when I saw a SDS drill for sale in Lidl it looked well-made and since I only wanted it for light work I bought it.

It did not work properly as in when I drilled a hole and went to pull the bit out the chuck would release the end of the drill bit and leave it in the hole. I checked and checked but the bit was properly engaged each time when I started.

I took it back and Lidl were great and refunded my money. I purchased a new drill in Argos and have more or less the same problem.

Would this be a problem with cheap drills or drill bits?

Are you removing the bit whilst the drill is still turning or is it stopped?

I bought one of those as well, have only used it in non SDS mode so far and it was fine. Hope it's not the drill

As fred mentioned, the drill should be turning when you withdraw from the hole.
Also if you are using long bits, you should clear the rubble out regularly by withdrawing the bit or it will clog and seize.

GMSA

Apply a smear of grease to the chuck end of the bit before use. Most likely the ball bearing that locks the bit in the chuck is stuck due to heat. Most drills have a tube or small tub of grease supplied with them.

You must not be inserting the bits correctly. They can be a bit fiddly at first but you get used to them. Highly unlikely 2 drills are faulty. Was it the same SDS bit? And if so, are you sure it was indeed an SDS?

Thank you for the advice, yes I am / was keeping the drill turning as I remove it as you would with any drill to clear the hole of dust.

Mention of grease is I think the answer. None came with the drill so I will get some as GMSA suggests it might well be down to the ball bearing in the chuck.

I am inserting the bits correctly, I Have used SDS drills before on sites etc. I did wonder about the drill bits but they are Makita brand plus I tried the ones that came with the drill.

As I said I will get a tub of grease and see what happens

Sorry to be blunt but you must be doing something wrong. For it to be happening with two separate drills is too much if a coincidence.
