It's suitable for both impact drivers and driver-drills, providing convenience in various electrical projects.

Using this Makita step drill bit is easy. First, select the appropriate size increment on the bit for your hole. If you're using an impact driver, the 1/4-inch hex shank allows for quick bit changes. Just insert the bit into the driver and you're ready to go. When drilling, apply steady pressure and let the drill do the work. For best results, start at a slow speed and gradually increase as needed. Here are some important notes. Make sure you're wearing safety goggles to protect your eyes from any flying debris. Don't force the drill too hard, as this could damage the bit or the material you're drilling. Also, avoid using the bit on extremely hard materials that it's not designed for. To keep your drill bit in good condition, after each use, wipe it clean with a dry cloth to remove any dust or debris. You can also apply a light coat of oil to prevent rusting. Store the bit in a dry place, preferably in a toolbox or a case to protect it from damage.
