straight shank adapter for MT2/MT3 drill bits

[John ReeseParticipant @johnreese12848]

Purchase an extension Morse taper socket. Mount it between centers and turn the male taper to a suitable diameter.

For use in a hand held drill motor sme runout is tolerable so it is preferable to purchase a used extensin scket and modify it.

RDG sell a 2 morse taper socket with a 3/4" diam.shank which could be turned down to 1/2" I should think.

2 mt socket

 

Scroll down to 3RD item.

The R8 to MT adapter linked by NDIY does not take tangs. I have loads of MT-MT adapters and drifts thanks Howard. If I cannot find a cheap adapter as per the OP request, then of course there are many possibilities to turn down other styles of holders. Thanks everyone – it seems we have exhausted the value of this topic. However I do agree with Bill that allowing drill bit slippage in the chuck jaws is a must for H&S

No imagination? It has a through hole for a drawbar?. If the drill bit in use is (as I indicated earlier) is less than the diameter of the R8, a punch, of some description (perhaps a bolt of the similar diameter) could used to remove any drill, while the R8 end was supported? Cut off the tangs (if they will not fit)?

I don’t agree with ‘allowing slippage’. That is not a reliable safety device by any means of justification. How to FU ruin your tools comes to mind.

I doubt turning down an R8 shank to fit a 1/2” chuck is a particularly satisfactory situation – asking to bend or twist the thin wall if it has a 10mm hole for a drawbar. Cutting hexagon or triangle flats would likewise be doomed to failure?

My advice, had the OP asked the appropriate question in the first place, would have been “Buy some suitable drill bits and forget the morse taper idea”.

NDIY, I object to your offensive tone but marvel at how much time you have on your hands to witter on and on in this fashion. Have you really nothing better to do ? My OP was clear and simple and appropriate, and rather uninteresting. You have simply gone off on your own tangent. Of course there are many solutions to modify various holders as anyone with half a brain knows. If John Stevenson was with us today he would surely categorize your responses as coming from the class of arm chair wind blowing so and so that he was so fond of rebuking

He’s not and I have been busy in my workshop in the interim. If you have such a thin skin as to think my post was ’offensive’, tough. Get a grip on reality might be appropriate advice for you. Blacksmith drill bits are for blacksmiths drills.

Obnoxious to boot!

NDIY, I have been trying to find a suitable name for those thin skinned people who can't handle criticism. I have considered names like snow flake, candy ass, etc. I finally settled on emotional weakling, abbreviated EW and pronounced EEWWW.

If you want to find harsh critics go to Practical Machinist forum. Sometimes they attack like a school of piranha.

Lets keep things civil otherwise I may have to lock down a few individuals.

There is more than one pair of eyes on this thread…
