Point Drill Bit
Physics -Mechanics?
When drilling metals, excess heat is avoided by staying below a recommended linear cutting speed. A 13.0-mm-diameter hole needs to be drilled. At what maximum number of revolutions per minute can the drill bit rotate so that a point on its perimeter does not exceed the material's linear cutting speed limit of 3.0 m/s? (rpm)
This question can not be answered without the material type, thinkness that your are drilling, the drill type you are using, Carbon steel, Carbide, Chromoly, Etc.
