Using the Greenlee GSB12 - B step bit is easy. First, make sure your drill has a 1/2” chuck as this bit has a three - flat shank that fits these chucks. Then, identify the size you need using the laser markings on the bit. When drilling, the durable split - point tip will quickly and accurately penetrate the material. Whether you're working on mild steel, aluminum, or other materials like wood or plastics, the bit's progressive cutting edges and patented split - step design will ensure fast and smooth cutting. Just be aware that the maximum sheet metal thickness it can handle is 10 gauge. For maintenance, after each use, clean the bit to remove any chips or debris. You can use a brush or a cloth. Store it in a dry place to prevent rust, especially since it's made of high - speed steel. If you use it frequently, check the cutting edges regularly for signs of wear. And remember, if you need a larger quantity, you can buy it in a carton of 25 pieces.
