Using your Bosch 8 - piece insert bit set is a piece of cake. First, open the durable case with the secure latch. Then, use the tilt - in/tilt - out mechanism to easily access the bits you need and snap them out from the clips. Once you've selected the right Phillips P2 1 bit for the job, insert it into your impact driver. When using the bits, don't push too hard as the Xtended Torsion Zone is designed to handle the torque. After you're done, snap the bits back into the clips and close the case. For maintenance, keep the bits clean and dry. Wipe them down with a clean cloth after use. Avoid dropping the case to protect the bits and the case's rubber bumpers. Store the set in a cool, dry place to ensure the long - lasting performance of your bits.
