This listing includes 1 set of titanium coated M35 cobalt molybdenum drill bits and 1 set of HSS Center Drill bits. The addition of cobalt gives the bits increased heat resistance and durability. When used with the correct feed and speed rates, these bits will provide excellent bite and lower wear rates when used on harder metals. The drill bits come packaged in plastic packs for secure delivery and storage. Please note that left hand drill bits work best when the pilot holes made dead centre of the broken fastener. It is also important to use a low speed and the correct left hand drill bit diameter when drilling into metal. This will ensure the bits stay sharper for longer. Eye, ear and hand protection should be worn at all times when using power tools. Tradeyak accepts no liability for injuries sustained whilst using our products.
