Which twist drill do I use to drill in stainless steel | RUKO
Stainless steel is a metallic material which is characterized by its special purity . There are alloyed and unalloyed steel, but only the alloyed variant is also stainless. In stainless steel, it must be enriched with alloying elements such as titanium, niobium or chromium in addition to iron. Chromium (Cr) is the corrosion resistance of stainless steel and should have a minimum content of 12% and an extremely low carbon content. The chromium content creates a layer on the material surface which permanently proteSee more on ruko.deWhich Drill Point Angle Should I be Using? | Regal Cutting q420 steel angle Hole drillingThere are two main characteristics that define a drill point. First is the included angle of the point and the second is the configuration of the point. The point configuration is a key element in the choice of drill styles for a particular job.See more on regalcuttingtools q420 steel angle Hole drillingWhere is the point angle on a twist drill?The point angle is located at the head of the twist drill. For hard materials such as stainless steel, the point angle should be large and e.g. 130° or 135°. For soft materials, point angles of e.g. 118° are used. With a large point angle, more of the cutting edge engages in the workpiece when drilling.See all results for this question
