Top 20 Black & Decker 3/8" Variable Speed Reversing Drill Kit" [Misc.] Questions & Answers

Possibly he brushes are gummed up / jammed - hence not making contact with armature.Remove and cleann brushes and brush holders.

All you have to do is take the model number and go to Sears to order a trigger switch. Take the cover off of the drill, take the wires off the old switch, and put the new one in. It is super simple.

just use two pairs of grips , one to hold the bit and the other to turn the chuck

I've run into this from time to time, usually have to fix it with two pairs of channel locks, one on each collar on the chuck. With the drill facing you, hold the inner collar steady and turn the outer collar counter-clockwise.The chuck should not stick like that under normal circumstances (mine only did it when it got full of sawdust), so there may be a mechanism issue and there is a fair possibility that you will break the chuck doing this repair. That being said, 30 bucks is reasonable for a new one, and it's not doing you much good jammed like that.

check the cable

i don't think you will find a diagram for the switch. find a parts schematic and order a new one. they aren't make to be fixed.

This drill has a 2-level chuck handle. one is slightly larger diameter, or is closer to drill body. It is fixed to the motor shaft. Smaller diameter, or forward one is the adjustment. Hold the rear/larger one stationary and twist the smaller/forward one as if you were opening a water bottle with a really tight lid.

IF ITS A LOW VOLTAGE ONE, LIKE 3.8 OR 6VOLT ITS TOO SMALL FOR THE JOB YOUR DOIN, OR ITS WORN OUT THE BATTERIES ARE NO LONGER GOOD, IF ITS A PLUG IN MODEL, I'D BUY A NEW ONE CAUSE THE BEARINGS ARE GOIN.

Make sure you try it in both directions.

the coil spring should be attach to the 2 carbon inside it

If the jaws of the drill no longer works, then, the drill chuck must be replaced. Take it off by turning the chuck
counterclockwise, and putting an open wrench at its neck to lock it. Then, after taking it off, you can now have it replaced.

This is typically caused by one of two things. Worn brushes or a bad switch. How old is drill and has it been used a lot? If the brushes are worn/bad they will need replacing. If the switch (trigger) is bad it can sometimes be fixed by spraying an electronic contact cleaner in it. This cleaner can be purchased at Radio Shack. I have also had good success using WD40. Spray the switch down good (power removed) and manually operate it a few times, wipe it clean, plug it in and try it again.

The switch near the trigger that toggles left or right controls that.

Good luck with your project, Kathleen.

Problem solved.

hold outside collar on chuck firmly with your hand and reverse drill

there is a rippled edge close to the very tip of the drill and there is a key supplied with the drill with the corresponding ripples place key into the hole near tip of drill so ripples meet each other and turn key in an anticlockwise direction to loosen put in new drill bit re tighten in clockwise direction hope this helps if not please ask for more info glenn

The motor does not go in reverse.

hi, have you seen this ? https://support.blackanddecker.com/hc/en-us/articles/360012702998-If-my-battery-is-not-charging-what-can-I-try-#:~:text=If%20your%20battery%20is%20not,charger%20to%20try%20charging%20again. Now i don't think that's the issue , it more likely the cells won't take a charger or the bms electronic board has failed , with those battery packs it can be a electronics problem or a failed cell , One thing you might want to check is the actual connection to the battery pack..i seen a issue here where there is a bad connection , the charger won't charge regards Rob

With that being said, be advised that leaving the screwdriver on the charger after fully charged may overcharge it and also shorten its battery life. Therefore, it is recommended to unplug the unit from the charger after charging.
