Using the Bosch ITPH21B bits is easy. First, select the appropriate bit for your screw size. Insert the bit into your impact driver. Make sure it fits securely. Then, place the bit on the screw head and start your impact driver. The precision-engineered tips will ensure a tight fit, reducing the chance of slipping. When using, don't apply excessive force as these bits are designed to handle high torque, but too much force can still cause damage. After use, clean the bits with a dry cloth to remove any debris. Store them in a dry place to prevent rusting. The high-visibility sleeves make it easy to find the right bit quickly, so keep them on for maximum convenience.
