Thank-you for the information Stuart and Curt. I guess what I need the slower speed for was for a little more control. For instance I replaced the bushings in my clutch and brake pedals. The original holes I believe were 13/16 and my replacement bushings were 7/8 o.d. I know that a reamer would have been the tool to use, but I drilled them out to 7/8. It worked OK but I just felt that I could have done it more accuratly if the drill wasn't spinning as fast as it was.
Thanks again.
Brian
