Specifications:-Surface Treatment:-Nitriding Black, while its surface treatment provides enhanced oxidation and corrosion protection, extending drill bits' service life and making them suitable for drilling hard metals and other materials.TIP:-When using a large drill bit, it's best to start by drilling smaller holes. This makes it easier to create larger holes accurately.-When ues reduced shank drill bit, it's important to maintain a 90-degree vertical angle to ensure precision and accuracy.-For power drills, it's recommended to use a model with a power rating of 750W or higher.-Use water or coolant to lower the temperature and prevent the drill bit from overheating, especially when drilling hard metal like stainless steel materials.Package Content:
