makita die grinder help

Hoping someone can give me a little help... own a GD0800C model. A cut off wheel bit sheared off, flush with the collet and is stuck. Anyone have any suggestions regarding extraction. Read a few things online but wanted to see if anyone had this problem before.

Steve,

I never had that problem but why don't you just loosen the collet nut? If the collet doesn't open after you loosened the nut, you can tap sheared end in gently (you can use a nail as a punch). that should open it up. If not....totally remove the collet nut and the entire collet should fall off. Good luck!

The nut was loosened all the way when I was trying to extract it... I think the problem is that the bit was put all the way in, to where the collet cone meets the spindle. It wasn't over-tightened or anything, just think that I can't break the metal-on-metal contact, even with rapping it with a rubber mallet and hand. People suggest a light rap on the bit inward to break the contact... Tried using a vice to hold the grinder in place and pull the bit, with nut loose, out of the collet and ended up shearing the bit flush off. May have to take it to a professional to get it out. After looking at the construction diagram, looks a bit complex to take apart and put back together on my own w/o ruining something.

Thanks for the advice though. Might look into a small extractor bit... just afraid to damage the tool.

Have you removed the nut completely?

Maybe try heating it with a plumbers torch or over a stove flame in a pair of pliers? Then into and ice bath?

I don't recomend this. It could demage collet

Neither would I.

I wouldn't get it red hot but it could certainly handle a little heat which might be enough to pop the pieces apart. I had a dremel tool that did something similar and I heated it up still on the tool and it freed it up in no time and di no damage.

I had read elsewhere people suggesting the heat/cool method. Soon as a have a spare afternoon I'll try a few things to free it up. Majority of the weekend is shot with a wedding... Maybe Sunday evening. Thanks for your suggestions. I'll let you know what works.

Isn't Makita the brand that Dale Cochoy carries? You might PM him.

do you have penetrating oil over there? it frees up siezed nuts and bolts - spray it on, wait 12hrs or so and try to seperate the parts - it often works wonders

I would try a penetrating oil as Marcus said--I had this happen once and I held the tool between my knees and took a narrow punch and alighned it on the tip of the broken shaft and gave it a sharp blow with a hammer.
