Feed equals.001" per revolution for every 1/16" of drill diameter, plus or minus.001" on the total. Speed equals 80 surface feet per minute in 100 Brinell hardness material and the speed should be reduced 10 surface feet per minute for each additional 50 points Brinell hardness. Drill Feeds and Speeds Viking Drill and ToolFeeds and Speeds - Formulas. R.P.M. = (3.8197 / Drill Diameter) x S.F.M. S.F.M. = 0.2618 x Drill Diameter x R.P.M. I.P.M. = I.P.R. (feed) x R.P.M.
