No, as long as you apply enough pressure to prevent the drill skidding on the stainless and use lots of lubrication - ooh err missus. You can "feel" the right amount of pressure that you need for an efficient cut. Make sure that the piece is securely clamped down, because I find that the drill invariably "catches" as it breaks through at the end. The swarf is razor sharp too I just use good quality HSS drills on the stainless that I drill. However, having written this, don't forget that not all stainless is uniform in composition, and sometimes you can get a real horror to work on - but you probably wouldn't want to make a knife out of that anyway Edited April 15, 2018 by amateur Quote Link to comment Share on other sites More sharing options...

old'un Posted April 15, 2018 Report Share Posted April 15, 2018 (edited) Stainless steel is easy to drill with HSS drills and coolant, but if you want to make life easy then tungsten carbide or colbalt drills, tungsten is expensive so colbalt might be a better option.

It is a 750cc Rickman Enfield that I have owned for the past 47 years. Having worn out, and sold, the Enfield engine I have now almost completed fitting a brand new Nourish Weslake 850 engine and Quaife 5 speed box. When I have got it going (rewiring and brake hydraulics to finish) I will write it up with pics in the motoring section Edited April 15, 2018 by amateur punctuation Quote Link to comment Share on other sites More sharing options...
