reduce rates when material is harder than listed, when drilling conditions are not optimum, or coolant is not available
rates shown are for drilling into a flat surface and should be lowered using the reducion multiplier when the workpiece is angled or curved
reduce rates 10 to 20 percent when using drills without internal coolant
always use the shortest overhang possible
longer drills may require a spot drill operation to avoid walking on entry
internal coolant required in ISO S and M material groups or when drilling depth exceeds 3xD
