Carbide-tipped drill bits are used for drilling into surfaces that can rapidly blunt steel drill bits, like drilling into masonry with hammer-action drills. The carbide adds to the performance of the drill. The hammer action blows, or heat generated from tough materials like steel, can create strain on drill bits. The carbide, although brittle, is exceptionally strong. Usually it's just the tip that's made from carbide; the rest of the bit is steel.

Install the extra handle onto the side of the drill if your drill has one. If you're using the hammer function, or drilling into tough materials, the extra handle can provide extra control and reduce tiredness. You may find the extra handle in the box that the drill itself was shipped in. It usually screws on.
Place the carbide-tipped drill bit into the drill's chuck and select the rotation direction with the switch. Install the battery pack, or plug the drill in, and set the mode setting. For masonry, choose the hammer setting and for hard surfaces like steel, use the non-hammer setting.
Set the speed switch to "Medium" for masonry or to "High" for hard surfaces. Hold the drill tightly and place the carbide bit at the point that you want to penetrate the wall or other material.
Pull the trigger switch and allow the drill to start boring. Increase pressure by pressing harder on the drill, but don't push so hard that you would lose your balance if the drill bit snapped. Drill to the depth you need, and, while keeping the drill turning, pull the bit out of the hole. Then release the trigger.
