This M35 cobalt HSS step drill bit offers high hardness and long-lasting durability for efficient drilling through a variety of materials. The 118° split-point tip reduces slippage and speeds up cutting, while the dual spiral flute design ensures fast chip removal and smooth drilling without overheating. With 15 metric sizes in one bit, it is suitable for stainless steel, copper, iron, aluminum, PVC, wood, and other sheet metals. The 3-flat shank allows for quick and secure installation in most electric drills. For stainless steel, use water to keep the bit cool during drilling.
