Made of durable stainless steel
Drill bits often need to apply a lot of pressure when used to drill holes in wood or aluminium materials. If no high quality material is used, the bits can be permanently damaged. To avoid this, Dudua has developed these drill bits made of durable stainless steel material that is not easily damaged. These bits will not bend or break even with regular use, making them a good choice for many applications. These drill bits have a length of 200mm (7.8") and are available in various diameters such as 2mm, 2.5mm, 3mm, 4mm, 4.5mm, 5mm, 6mm and 7mm.
