(4) The M42 metric cobalt drill bits can cut through Stainless steel and Hard metal,Hard wood, although they can be used for softer materials such as Aluminum,Plastic. Some Important Tips about drilling stainless steel and hard metal: (1)Controling the drill speed from 200 to 1000 RPM would make it easier for you to drill holes on stainless steel. ________________________________ Stainless Steel ____________________________ Drill diameter RPM ____________________________ ≤5mm 1000~700 ____________________________ 5-10mm 700~350 ____________________________ 10-15mm 350~200 ________________________________ (2)Add stainless steel tapping oil or engine oil to prevent the stainless steel from overheating and forming a very hard oxide layer.It also works adding some vinegar,soy sauce or water if you don't have engine oil.
