These High Speed Steel (HSS) drill bits are ideal to drill 4 - 22mm Holes Required for Hydroponics

For best results in stainless steel or metal make sure to drill slowly (less than 600prm). Use significant pressure when drilling and also use cutting lubricant to lubricate the cut but also keep the bit and metal that you are cutting cold.

NOTE: If fast drill speeds are used the metal and bit will heat up and the bit will loose it's hardness and not last as long.
