Owning a power drill can be a positive experience for many homeowners, enabling you to add and change fixtures and fittings to your home, or make a much-needed repair. Once you own a power drill, the possibilities are endless, providing that you understand the need to use different drill bits for different situations and materials.You should also decide whether you want your power drill to have a keyless or keyed chuck system for changing your drill bits. Most current power drills will offer a keyless chuck system.
Changing a DeWalt Drill Bit
The part of the power drill which effectively holds the drill bit secure is called a ‘chuck’ which contains three elements that will either open or close dependant upon the rotation used. It is important to ensure that when you change the drill bit on your power drill that the drill bit is placed directly in the center of the chuck; misaligning the drill bit will mean that your drill bit is not secure and therefore may spin off-center when using the power drill.
Removing a Drill Bit
To change the drill bit on your Dewalt power drill, first, ensure that the power drill is completely turned off and unplugged so that there is no power to the tool whatsoever. Hold the existing drill bit securely and then rotate the sleeve in a clockwise motion to widen the jaws of the chuck. The jaws of the chuck will gradually expand and then it will be possible to easily remove the drill bit.
Inserting a Drill Bit
If the new drill bit is smaller than the previous drill bit, the sleeve may require tightening so that the jaws are positioned closely together. Insert the new drill bit and rotate the sleeve clockwise. To insert a larger drill bit than the previous drill bit, rotate again to widen the jaws of the chuck. Alternatively, you could slowly power the drill in reverse to insert a new drill bit. After ensuring that the jaws of the chuck are a reasonable size for your drill bit, insert the drill bit and then tighten the collar.
This is done by rotating the collar in a counterclockwise motion until you can feel that the drill bit is locked in place and is fully secure. After you have ensured that the drill bit is secure, check that the drill bit is positioned in the center before using your power drill. Point the power drill in the air and press the trigger, checking fully that the drill bit does not wobble and that it is fully secure.
If your power drill possesses a keyed chuck, then the tool will contain three holes which are located in the chuck. These three holes will loosen and tighten the drill bit. The required key must be inserted into one of the holes and then the jaws and the chuck will begin to move. To remove or insert a drill bit into a keyed chuck, follow the same steps as above, although the loosening and tightening must be done with the necessary key.
Ensure that the drill bit is centered effectively and that the drill bit is secure before using the power drill on your home or work project. Test the security of the drill bit by pointing the power drill in the air and pressing the trigger, assessing whether the drill bit is wobbling and needs securing effectively, or whether the drill bit is secure and tight and therefore ready to work. You are then ready to work through your home DIY and work projects.
