automatico Posted January 15, 2016 Report Share Posted January 15, 2016 "I have had good success with stainless cases using HSS bits and my drill press set to 600rpm." I had some 1.3mm HSS bits quickly get hot and dull at low speeds when cutting lug holes maybe because the cutting oil was too slick. (?) Now I use a new bit dry and change it when it starts to get dull, usually after 4 passes. Drill bits are cheaper than cases. Quote Link to comment Share on other sites More sharing options...
