Drill turns in a wobble?

Question

I bought this drill a while back and it seems to me that it turns with a slight wobble. i have a couple of question about this.

1) how can i check this forsure

2) did it come like this or is it possible that i did it, how?

3) and most important, how can this be fixed?

Thanks

Answer 1

You can check for wobble with a tool that checks for runout, but if it seems to wobble it could be a bent drill bit. Generally this can happen if the drill was dropped with the bit in it. Change the bit and check. If that still doesn't work you can buy a new chuck for the drill.

Answer 2

I am assuming that this is a hand drill and not a drill press. Chuck up a small piece of steel bar stock 1/4" or 3/8" about 6" long will work. Lay the drill on the side and lock it to your work table with a clamp to make sure the drill does not move. Slowly apply speed to the drill and check for wobble. If it wobbles your chuck is on crooked. Open the chuck fully and insert an allen wrench in to the chuck. There is an allen nut at the bottom holding it in place. Now comes the fun part. Loosen the nut, but do not tighten the chuck. Use a strap wrench to hold the chuck still. The nut will be extremely tight! Once you loosen the nut tap the top of the open chuck down on to the body of the drill, but make sure you hit square to the drill, and use a block of wood on top on the chuck to prevent damage. Tighten and check again with the steel rod. If it still wobbles replace the chuck. Check the manufacturer's web site for replacement parts.

Or if this is too much work, take it back or buy a new one. A good corded drill is only $100. Don't buy the el cheapo. You will end up with a drill that wobbles.

Answer 4

Hi I'm a Toolmaker the drill is bent
1. Lay the drill down on a flat surface and roll it to see where the bend is. If it is at the top where the drill chuck holds it it can be turned in a lathe to straighten it. If it is a small drill it would be cheaper to buy a new one.
2. Not likely. drill are checked for straightness by laser scanners.
3. See # 1 answer

Answer 5

Put a bit in the chuck with the bit on a flat surface turn drill slowly, if the bit moves up and down or side to side the chuck is probably bent. You can replace the chuck on most drills, but the cost to replace the drill itself is probably cheaper. You can bend the chuck in many ways, one common way is putting uneven pressure on the drill itself, try holding the drill with equal pressure on the top. Good luck and I hope this helps.

Answer 6

Does it drill oval holes?
I would guess the drill was dropped and bent the drive of the drill. I am not too sure about if it worth saving.

Answer 7

The big wheels with spokes unfortunately these are not designed to take the roll of a bus with you sitting in it, their strength relies on the 3-4 spokes hanging from the top of the rim unless the spokes aren't tight enough all the way round the rim but I think you may need solid wheels like some of the sports chairs you can get and that would give you the sideways strength you need

Answer 8

Either a bent bit or it's not inserted correctly.
Just try again.
