  • Cobalt drill bits and reamers are specifically engineered to provide heavy-duty performance on high tensile metals; these are manufactured from a steel alloy with between 5% to 8 % cobalt content. The 5% cobalt alloy is designated as M35 grade and the 8% alloy is graded as M42. Cobalt increases the strength of the parent alloy and significantly increases its heat resistant properties; these are two very strong considerations when drilling stainless steel as heat resistance to friction created during operation will reduce the work hardening rate, and the additional strength will protect against bit breakage and flank and crater wear. Flank wear is when the part of the bit in contact with the workpiece wears away, crater wear is when the metal from the drill bit becomes diffused into the swarf. - Source: Internet
  • Feed rates can be high when drilling stainless steel. Not only will this increase the effectiveness of the tool, but it will also more effectively evacuate chips. It’s important to ensure that the feed rate is maintained and that you regularly check that heat isn’t building up in the material or the tool. If it is, then be sure to give it time to cool down. - Source: Internet
