Broken Forstner bit

Featured Replies

I had a bad oops yesterday. I was redoing a part of my turning station and dropped a MAxi-Cut bit in a Jacobs chuck with MT. I have sent the company a note to see if there is recourse today. Now I am looking at solutions so I can use the bit. The stem (elliptical 3/8) all broke off , leaving a 5/8 shaft. I am thinking I can use the bit if I can find a forstner bit extension with a 5/8 female. Only need this to be 3 to 6 inch.

 

I have looked every where I can think of and cannot find a  extension . Any ideas or places to look are appreciated .

What of a welding shop?  Maybe, they/he/she can make the desired extension and have the right metal rod to make it as durable as before and as strong as before.  That's my only idea.  :unsure:

Gerald I know how you feel. Just recently I dropped a solid carbide 1/2" Magnate up cut bit # 2269.  It broke half in two.... I only paid about 65.00 when I bought it but now it sells for 81.00.

   I didn't even think of seeing if they could do anything for my screw up...I just hung it up so I see it real often……. for a reminder to be more careful...

Yes thought about that but the bit is only about 40 and machine shops just get started at that rate. I was wondering about drillin out a 3/8 extender but will wait for response from Colt.

There are collet chucks out there but they may be the same price as a new bit.

Thanks Dan. Will look into that. I was thinking of maybe drilling out a 3/8 to 5/8 . Even if it fails I would only be out$12.

Dan brought up a point that may have real merit.  If you could put an extension on the router collet and then insert another collet on the extension shank to hold a second collet, I wonder if the 2 collets could withstand the torque?  Any engineers here?  Ok, I've run out of ideas or further help on this thread.  I wish you great luck there, Gerald.  And, I am very interested in outcome.

Thanks Steve . I looked at collets and for that price might as well get a new bit

I have some router extension collects in 1/4 and 1/2" if this is what you are talking about.IMG_2299.JPG.4f3dff7ad540d2557a0c668a37071042.JPG

  I use them on the Legacy Mill. This I think is the only length made. Sometimes a router don't get in there far enough

Thanks Kevin. I got it to work in another chuck but really want to put an extension on it. Give me an address and I will send to you.

Then how about I make you an extender?
