Using your Makita Impact GOLD #1 Phillips Insert Bits is easy. First, make sure your high - torque impact driver is turned off. Insert the bit into the driver until it fits snugly. When you're ready to start working, position the bit on the screw head and start the driver. You'll notice how smoothly it drives the screw in. These bits are great for a variety of heavy - duty jobs like building decks, framing, or installing plywood subfloors. Just be careful not to over - torque the bit. Using too much force can cause unnecessary wear. After each use, wipe the bits clean with a dry cloth. This helps to keep them in good condition. Store the bits in a dry place, away from moisture, to prevent rusting. If you pair these bits with an Impact GOLD® bit holder, they'll last even longer, giving you more value for your money.
