-A Dremil tool has many uses from cutting to polishing metal. Always wear a face shield when using this tool. \\ +Below is a bulb type pressure tester for testing the carburetor needle seat valve as referenced in TSB #564. \\ 
-It operates at a very high speed and tiny pieces of the cutting bits and the metal will hit your eyes faster than you can blink. \\ +It's for use in testing the seat valve of Tillotson carburetors used on 1966-later Sportsters and 1967-later Electra Glides. \\ 
-It's good for cutting carbon & stainless steel, shortening bolts, shaping metal projects etc. \\+[[techtalk:miscres:miscres05#tsb_550-599|Click Here]] to go to the TSB page, scroll down and click on the "Y" next to TSB #564 to download the bulletin. \\
