Alloyed with Cobalt to improve heat resistance which will perform and outlast normal HSS bits particularly if your work invoes drilling tough metals. 7.Can be used radial drill, bench drill or hand drill chuck for drilling operations. Notes: 1. The drill can drill stainle steel, but proceing stainle steel and other high hardne of the workpiece, it is recommended to be fixed on the drilling machine or platform type machine, the use of electric hand drill is prohibited, because the artificial use of electric hand drill is easy to shake, resulting in insufficient proceing accuracy Or the bit gets dull or even breaks. 2. The bit and the workpiece to be proceed must be fixed or clamped. Generally, the rotational speed is le than 2000RPM. The larger the diameter of the drilling hole, the lower the rotational speed. The harder the material is, the slower the speed is required, and the more durable the cutting fluid is recommended. 3. Can dry cut stainle steel and other high hardne metal, but continuous uninterrupted work is best to add water or coolant cooling, prolong the life of the product.
