Do I need new collets? Can't insert bits into either 8mm or 1/4 for OF 1010

[mutterback]

Hi - During a prolonged move, I had my tools in storage for about a year. Now setting up my shop again, went to use my OF 1010 yesterday and I can't insert either 8mm or 1/4 bits into the collets. There was a bit of corrosion inside the nuts, which I believe I cleaned out fully. Reassembled... still won't fit.

Any tricks or tips, or should I just bite the bullet and buy 2 new collets?

Thank you!

Hi,

  Welcome to the forum!  [smile]

    How did you clean them?

  I suggest soaking in a cleaner to make sure all the nooks and crannies get thoroughly cleaned.

Used a rust eraser, then a rag with 3 in 1 oil.

What kind of cleaner would you use? Would rather get a general purpose tool cleaner vs. router bit cleaner, as I don't use the router that often.

If the corrosion is in the bore of the collets, get .25 and .32 caliber rifle cleaning brushes, chuck them into your CXS, dunk them in Hoppe's No. 9, and have a go at the collets.  The brushes are bronze and won't hurt the collets.  Alternatively, a good soak in Naval Jelly might do the trick.  [smile]

Thank you! Will give it a try. There must be something inside the bore of the collets. I never had any trouble getting bits in previously....

Suspend them in a Extreme Simple Green aircraft and precision cleaner over night. Remove from solution rinse with water and blast them with compressed air. I have soaked carbide tipped blades with heavy pitch and resin, using this product, over night and the next day they sparkle new. No brushing needed.

I’d try 3M 800 Wet or Dry with light oil applied on a mandrel to lightly burnish the inside diameter of the collets. It probably won’t take much as everything is a close tolerance fit. Don’t reef on it just a simple kiss and a promise.  [big grin]
