Ozito Hammer drill wobble issue

Hello

I recently got the Ozito Hammer drill(PXBHS-100).

I am using it for the first time today and I was trying to screw into a wood in Gear 1 setting.

I used an adaptor chuck for the screw bits and the chuck wobbles so much that it feels to me the screw might not go in straight.

I removed, inserted it straight etc to try and fix the wobbling but no success.

The wobbling is no there in Gear 2 though.

I have attached a YouTube video to demonstrate the wobbling.

What am I doing wrong here. Please advise.

Thank you

Sam

Hi Sam @nsavi,

There could potentially be an issue with the bit or the drill, but I find it much more likely that this wobble you are experiencing is just a characteristic of the drill. I've checked all three of my Ryobi drills, and they all exhibit a similar, if not worse, wobble. If I put on a 200mm extension, the wobble becomes extremely noticeable. To be honest, I don't pay any attention, nor have I really noticed it before, as it doesn't impact the tools' ability to drive in screws. I presume the wobble appears to go away on the higher speed setting, as the faster the bit spins, the harder it would be to see the issue. I suspect you'd find on premium range trade quality tools the tolerances on parts are closer and the wobble less noticeable.

Have you tried putting some screws in with it? I think you'll find once pressure is applied and the screw bites into the timber, the drill will self-centre, and there won't be an issue. Try a few practise screws in a scrap piece of wood and let me know how you go.

As always, our team in-store would be happy to take a look at the tool for you to check to see if it is faulty.

Let me also mention @TedBear and @r23on to get their thoughts.

Please let me know if you have any questions.

Hi I have had this issue with other drill. brands and have found I have not place the extension into the chuck correctly hence the chuck has not tightened correctly.

Also looking at the bit extension at the lower speed it still has that wobble.

There are other possible issues the chuck it’s self, the chuck jaws not seated correctly on manufacture and is a common fault

place a drill bit into the drill and see if it does the same. If not it is the bit extension is bent.

It can also be a bent shaft or poor seating of bearings.

all possible issues

But as I said place a drill bit into the drill and check if it does the same. Like all mass manufacturing there will always be a number that turn out faulty.

Just watched the video. You are inserting the extender far too deeply into the chuck, so that the jaws can't move foward enough to grab properly.

When fitting anything into a chuck always leave some slack.

The extender also appears to have a hex and a square section, so putting it in so deeply means the jaws are trying to contact 2 different surfaces and won't get a good grip on either surface. Just insert the hex section and tighten up on that.

I have just taken another look at the bit extender and it has a square shank. The drill chuck has three jaws and its trying to grip on 4 surfaces and will never run true nor will it grip correctly. Now if it were a 4 jaw chuck that would be a different story.

If the extender had a hexagon shank the chuck will grip correctly. As stated if you place a drill bit into the chuck and it runs true you have proven the drill is Ok.

To clarify, @r23on and @TedBear, that is a standard hex bit and hex bit extender and there are no square sections. It appears to be a bit of an optical illusion because of the angle it's being photographed at. I'm sure @nsavi will be able to clarify that for us as it would be good to rule out jaw misalignment on a square bit.

I can confirm that the extender is a hex not square and I tried as advised by inserting the extender not too deep but just the bottom part of the hex. Also tried to align the edge of the extender hex with the lines inside the chuck(last picture) and also the flat side of hex with chuck.

But still wobbles

Hello @nsavi

Thank you for that update on your extender. Have you tried other hex bits on your drill? If yes, I suggest trying this method, loosen the chuck until it is only big enough to accept the hex bit. Try a position where the flat sides of the hex bit are firmly held by the chucks pincers. Slowly pull the trigger of the drill and observe if it still wobbling. Remove the hex bit and try placing the hex bit in another position. In theory, you should hit the sweet spot in three to five tries.

However, if you are still getting the wobble, I recommend bringing it to the local store where you purchased it and speak to the tool specialist and ask them if the drill is functioning properly. Once the tool specialist has made their diagnosis they will then proceed to make a determination if it is to be exchanged or not. Please make sure to bring your original packaging and docket.

If you need further assistance, please let us know.

Thank you. I did try few positions as recommended but still the same.

I might have been unlucky this time and got a defective one. Will go into a store to get this examined.

Same with the drill bit wobbles.

Please see this video.

@nsavi that looks unacceptably bad. I hope they replace it for you.

EricL

Hello @nsavi

I'm sorry to hear that the testing method did not work out. Thank you for posting the video clips. We have at least eliminated the possibility that it could be your drill bits. Please remember to bring your docket and the drills original packaging to the store.

If you need further assistance, please let us know.

Thanks for the video That basically tells me the chuck is at fault by the same token I will check with two different standard drill bits just to be sure . Also at one stage square shank extenders were available for the use in hand held interchangeable screw driver handles, I am not in my home location where I do have a set and yes it is old.

Despite reading this post, I recently purchased an Ozito Drill for my grandson, just to get him started with some tools.... and the chuck wobbled!

(I can't say I wasn't warned.) Took it back and found that each one I tried at the shop was the same.

My grandson was with me and he determined that this would be acceptable for his current needs (especially when compared to his not having one at all since we would have to wait for the next model up to be available due to transport problems to the west) and that he was willing to then upgrade to a better one, of his own choice, when he started work.

So we kept it, with its characteristic "Ozito Wobble". At least he has the battery & charger now... and a motivation to get his first job.
