Q & A: Rusty Router Collets


Q & A: Rusty Router Collets


Returning to my shop after working outside this summer, I noticed a rusty film on my router collets and bits.What’s the best way to remove the rust without damaging the collets and bits?



Use a synthetic steel wool or 3M Scotch-Brite pad. To clean a 1/2-in. collet, wrap the pad around a 1/4-in. dowel and spin it inside the collet. Clean the rust off the bit shanks by rubbing the pads around them. Do not use an emery cloth or sandpaper; you don’t want to remove any metal that could cause the bit to wobble later. Wipe the collet’s inside and the bit’s shank with a light, general-purpose grease, then wipe off the excess.A thin film of grease will remain in the surface to slow future rusting.
