You like working with your Bosch drill to make home repairs or on the job site, but you have lost or misplaced your chuck key. Your drill is still as good as new. You cannot see parting with your high-quality, durable drill, but what good is a drill with a missing chuck key? Perhaps you could purchase a new chuck key from the extensive roster of Bosch parts on hand. However, the part is obsolete.



Fortunately, Bosch made a useful keyless chuck replacement part for your drill in anticipation of circumstances like yours. You can change the part you need with the new 330075-63 and will not need the phased-out 330075-66 anymore. It functions with the DW971K-2 Type 6, DC920 Type 1, and DW990KQ-2 Type 4, to name some.



You need to change the old chuck with the new Bosch keyless chuck part as soon as you get it. Replacing the chuck is quite simple. Totally open the drill chuck. The screw inside may be flat or need an Allen wrench. Take out this screw. To unscrew the chuck from the drill, slide it off or give it a quick twist. Replace the chuck with the new Bosch keyless chuck once it's taken out. Be certain to tighten the chuck and screw totally. Your new Bosch keyless chuck may fall off if it's not screwed on tight. This is highly hazardous.



With the new Bosch keyless chuck installed, you'll be able to use the drill right away. If you're not familiar with using a drill that has a keyless chuck, you might feel a slight difference when compared to the old variety. It may give less torque than what you were used to. This is just a small disadvantage, however.



Switching to the new keyless chuck provides you convenience and speed as a benefit since it conserves you valuable time when switching from drill to screw bits. You can secure or loosen the chuck by only gripping and giving it a slight twist of your hand.



Do not lose hope if you lose your chuck key. You'll find a Bosch keyless chuck replacement part for your model. It is a simple repair. Soon, you and your trusty Bosch drill will be back in business.
