Cleaning the tiny passages of your Carburetor is an essential task during the Carburetor rebuilding process. These tiny passages are to small to be cleaned by soaking or bead blasting which can further plug the idle passage. These drill bits should be hand held and used to ream the internal fuel passageways after the brass plugs are removed.

Our long lasting Aircraft grade drill bits will last for years for this type of rebuilding work, finished in a black oxide coating.
