Tighten the chuck using the chuck key if possible. Most battery operated drills will not have a chuck key to tighten the bit. The drills with cords will have a tool called a chuck key hanging from the cord. Place the little round nub of the key into any of the three holes located at the base of the chuck. The teeth of the key will interlock with the teeth of the drill chuck. Turn the key so that it tightens the jaws of the drill around the drill bit.

YBG201 Coating PVD Tin coated carbide grade with good toughness and wear resistance. Good for threading and drilling (both peripheral and central inserts) on low carbon of steels, stainless steel, heat resistance steel, and cast iron. Full Profile insert The insert forms a complete threading profile including crest and are most commonly used in a high productivity threading Correct depth, bottom and top radii are formed therefore creating a stronger thread Stock does not need to be turned to the exact diameter prior to threading and no deburring is needed after threading Topping should be .0012-.0028"; let the threading tool finish the diameter Each insert can only cut one pitch and profile A full profile insert normally has a larger nose radius than a V partial profile therefore fewer passes will be required

Place the bit into the jaws of the drill. Drill bits will have different types of shafts depending on what they are made for. Make sure that when tightening the jaws that the bit shaft fits snugly against the jaws of the drill.

Putting a bit in a Dewalt drill is an easy task. There are several types of Dewalt drills on the market, but they all have chucks and jaws located on the front of them. The chucks will look different on battery-operated drills than on those with power cords attached. The chuck key also comes in several different sizes; heavy duty dewalt drills will require a larger size chuck key than the smaller drills.
