Keyless chucks are great BUT.....

BUT - Where are the drill sets with 3 flats ground on the shanks? THAT would make life so much easier! :?
 
I used to work in a toolroom and it was easy to put a drill bit in a V block and put flats 120 degrees apart using a 30,60,90 triangle on a surface grinder. Even in keyed chucks the flats help a lot. Does make you wonder why they aren't made that way.
 
How do you get them to release the bit? I have 2 drills right now with bits locked in the chuck and no way will they release the bit. Thinl I would have to take the grinder and cut them off but then where to get a replacement chuck and ebay is out of the question.

just get large pair of pliers and grip the chuck and give it a quick jerk and that usually releases the bit.
 
Leroy I have that problem when I use a hole saw in the drill press. A couple of channel locks is the only way I can loosen it. With a hand drill, I don't know. Jim
 
I have an Irwin drill index (1/16-1/2 by 64ths) on my service truck. Don't know the cost as they were company purchased but I do know they came from. Whitecap Construction Supply and have been pretty good bits.. sizes above 1/4" or so all have flattened sides.
 
No problem...Do you have a FastNail store near you? They have very good drills that are Viking. These are the same ones that"Whites drill bit city" sell. Whites has the three side jobber drills that you need. Give them a call. They are not cheap but good golly do they cut!
 
I had a drill get chuck in a keyless chuck one time,
wrestled with pliers, etc. Ended up using a small
pin punch placing it on the end of each jaw and
lightly tapped with a small hammer.One time around
and was able to open the chuck by hand.
 
I set up my lathe so I can mount my 4-1/2" side grinder on the tool post, and grind the 3 flats on my large drill bits. Just put a small level on the jaws of the 3 jaw chuck.

Kinda the way I've been doing it too BUT I'd pay a bit extra for a set that was already ground. Seems like some outfit like HF would jump on a nnalert-card like that. :?
 
I have a set up to 3/8" with the 3 flats. If the bit grabs, it breaks 'cuz it can't slip. Have broken several of them!
 
Tried even holding the base of the chuck in a vise and using about a 20" pair of channel locks and will not budge.

That's about what I've been doing but I use the jaws on the 3-jaw to index on the near-side bed rail :)
 

I have these chucks (#25013) on my DP"s. They grip round shanks and easily release. Occasionally, they need help to release.....a strap wrench (rubber variety) does the trick.
