I think his drill bit was probably SHOT .. the Keyless chukh is probably ok .. but you can still get like .005 " runout on them, they are not perfect ..
if the wobble was caused by metallic debris or dirt between your old arbor and spindle interior, you new cluck/arbor is going to wobble as well, even a premium one. Please update this video instructing to clean both your new arbor (they come greased to avoid rust forming during transit) and spindle insides with kerosene or alcohol. A clean and neat metal to metal surface contact is needed to keep the arbor and chuck in place. Also , if you got your new chuck and arbor as separate pieces, you need to clean the protection grease from bot JT33 ends before connecting them. Do not push you chuck up your spindle with a metallic hammer, you'll damage your chuck, use a rubber hammer or a piece of wood between your regular hammer and chuck, a couple of firm strokes will do, but just "getting it up there" with a quick trust will not be good enough, it migth stay up without falling, but the first time you apply any considerable lateral force on your drill bit you chuck will fall.
Keyless chucks are great but don't think they can't be screwed up with bad practice. They are taper mounted to the shank and can be broken loose if you try to use a large reduced shank drill which may ruin the chuck , the shank or both. To avoid this , never exceed the rated size of the chuck with a larger reduced shank drill. I learned this the hard way and am giving you all the chance to avoid my mistakes.
My old chuck had 40 thousandths runout, but the adapter MT2-JT3 was just fine, so I found a JT3 chuck, 5/8". (good ones are maybe $75 and great ones $200) I tried the runout in various orientations am down to about 0.004". I really would suggest getting a cheap dial indicator if you don't have one before you start throwing money at a crappy drill press.
OR, If you know how to RE CONDITION a Chuck .. you can easily get it to within .002" Run out .. which is HALF of what the Keyless Chuck guarantees you out of the Box ..004- .005. It's very similar to how a Lathe Chuck Works, and those get adjusted every time you run a Part to get it perfectly centered.. On a Drill press Chuck you have to Grind all 3 Fingers / Jaws to grip at exactly the same time ,, which is not easy, but it can be done if you know how to do Surface Grinding ,and Lapping, sometimes its as easy as removing some Burrs which have been caused by mishandling the Chuck over time .
I believe what you're referring to is called a spanner wrench. It works with the geometry of the keyless chuck and the hole in the tightening ring to tighten the chuck beyond hand tight.
2:31 Looks like you wasted you money as I still see it wobble. I'm guessing it's the quill that has free play. Could be the arbour also. Throwing money at the problem would have been better served in getting a decent drill press to begin with. Like they say, you can't polish a turd
Hilarious because I'm not trying to be a machinist on here, it performs beyond what I need it to now. Not everyone needs perfection and.0005" tolerance
@@EpicTim On second view it might be the camera wobbling, difficult to tell. Because at 2:43 the bit seems to be good, but the chuck housing has a wobble. I'm guessing it's just the grip around the housing that isn't seated true, which doesn't matter in that case. In any case if it's good enough for you then that's good. Sorry for my choice of wording earlier. In retrospect it was a bit rude, and you do have the keyless chuck upgrade even if the main problem isn't entirely fixed. Also, here's a tip I recently learned to keep the bit more true: rotate it as you tighten the chuck, in case there are burrs or debris on the bit or in the chuck. It will help push it out the way and keep it perfectly centred.
You can polish a turd. That is the sole purpose of Eaton and its ilk, we have a government full of them. Unlike intelligent people they think they know everything, it's the confidence of ignorance. Vote for polished turds and get shit government. The evidence is in Westminster.
