Given that the Cutting Speed is 100 feet per minute and the Diameter is 13/16 inches, we can substitute these values into the formula:
RPM = (100 * 4) / (13/16)
After calculating, we get:
RPM ≈ 492.3
So, the RPM required to drill a 13/16" hole in mild steel with a cutting speed of 100 feet per minute is approximately 492 (rounded to the nearest whole number)
