Questions & Answers
Yes, the Micro Grabit® 4 Piece Kit includes the Micro Grabit® 1, which is rated down to 3mm head size, and the MacBook Pro 13" Retina uses a total of eight 3 mm and two 2 mm screws. Externally, 3 mm pentalobe screws are used to secure the case's bottom plate to the internal frame.
While I can't speak to your specific faucet, many of them have small screws that this kit would work well with.
It is not something I would suggest. The Grabit is intended to remove a screw (in your case, a drywall screw) from which the slots in the head have become worn or damaged to the point where the driver can't get enough "bite" to turn it. The Grabit drills a hole in the head of the screw to the depth and width required for reverse-engineering. To turn and back out the damaged screw, use a threaded extractor with enough "bite." I'm guessing the screw's head broke in your case. The Grabit can't do its job because there isn't enough metal surface. If the screw stem extends beyond the drywall surface, I'd recommend grabbing it with a pair of vise-grips and turning it out. However, drywall crumbles like a stale cookie, so proceed with caution. If the screw shaft is below the drywall's surface, use spackling and a putty knife to repair it.
The screw sizes for these can be found on the manufacturer's website. I believe these will work, but please double-check the website.

Easy Removal Of A 2X4 Screw From A Dell Laptop This is a fantastic set for small projects. This extractor set is ideal for screws with damaged heads that are smaller in size. I needed to repair a Dell Precision laptop, but one of the two M2X4 screws holding the base in place had completely obliterated the Philips cross. There was no space for a needle-and-thread holder. This was the end result of my nose approach. For larger screws, there are numerous extractors available. This is the only set I could find with a M2 screw bit. br>br>The method is to use the burning end to make a hole of the desired shape. After that, the screw end should turn in and make a purchase. When looking at the screw, both the screw and the burnish end are designed to turn counterclockwise. A clockwise or anticlockwise screw thread is the polar opposite of a normal (right-hand) screw thread. This removes the screw by turning it in the opposite direction. br>br>You don't want drill shards from the burnishing end to get into the case of a laptop computer! I wrapped the screw in plain old scotch tape with the sticky side up. The computer was kept clean by the sticky surface, which kept the small metal bits out. br>br>The extractor (screw) end of the tool did an excellent job of removing the stuck screw. This was done with a reversing variable speed drill. All of the turning was very slow, which was ideal for this application. br>br>I give this set 5 stars. I mean, how could I not? It came in handy and helped me finish the job quickly and efficiently.
I was hesitant to even try these after reading some of the negative reviews. I decided to return and write my own review after using them today. br>br>First and foremost, do not bother if you believe this will solve your problem in 5 minutes. Pay someone else to take care of it. br>br>1 pay attention to the instructions! This will be impossible if you do not read the instructions. 2 patience! br>br> It will take some time to get down into the bolt you're trying to extract if it's made of any decent grade steel. Work at a slow pace, as directed by the directions. br>br>3 if you don't have access to a drill press and must rely on a hand drill instead. There's a proverb that goes like this: You'll need to put some sweat equity into it. Even a small valve cover bolt was no laughing matter for me at 225 pounds. br>br>To cut a long story short, these were fantastic and saved me a lot of time and money. With a hand drill, I probably took 45 minutes to remove a broken valve cover bolt from the head of a Honda civic. That's assuming I already know how to do it and have the stamina to keep going. It's possible that it'll take you three times as long as it took you the first time Depending on the situation, it could take up to four times as long. br>br>I would strongly advise others to purchase these. I was able to save the day.
On my laptop, there were two small (T2 size, 3mm) stripped screws. I tried everything I could think of, including a rubber band, superglue, and WD40, but nothing worked. The screws were completely stripped, and there was no traction at all. Then I went out and purchased this extractor set. I carefully followed all of the written instructions. I used a standard battery-powered drill and inserted the smallest extractor bit into the chuck. Set the drill to reverse (this is critical) and begin drilling the stripped screws with very light pressure on the drill button. I reversed the drill bit to use the extractor portion after about 5 minutes of careful drilling and slowly operated my drill once more. The screw came out with a whimper! The second screw is the same way. I never had an issue with the extractor bit breaking. You should be fine if you drill and extract with caution and do not apply excessive pressure.
For M3 screws, use the tool with the smallest diameter. I had a stripped screw head and a tiny M3 x 10 screw locktitted in place. A $300,000 industrial robot was brought down by this tiny piece. I was able to complete the disassembly for repair the next day because it was delivered the next day. br>br>Keep in mind that you'll need cutting oil for this job, and you should take your time drilling out the hole. br>br>The procedure is simple: use the cutting side of your drill (I used a 3/8 inch electric drill) with cutting oil and a very low speed in REVERSE to cut into the damaged screw head. Every 5 to 10 drill turns, come to a halt and clean out the hole for a few seconds. Continue drilling until you reach the beginning of the cutting tool's hex part, then add more oil. br>br>Then reverse the tool, add a drop of cutting oil to the threads, and let it soak in, then slowly drill into the hole you just made with the drill still in REVERSE. When the tool reaches its lowest point, the screw begins to emerge. When drilling the pilot hole, the instructions state that you should avoid drilling in the center. I wasn't in the exact center when I pulled my screw out, but that didn't matter because the screw came out as easily as you could hope for.
Updated once more - The replacement bit that was promised to me was never delivered. As a result, I'm stuck with my original opinion. When trying to remove a very soft screw, the bit broke. While I was initially impressed with their prompt response and willingness to replace the broken part, that was over a month ago, and the replacement has yet to arrive. br>br>Recently updated review: The seller responded quickly and has promised to send a replacement for the broken piece. Based on that, as well as my success using the other bits on a different screw, I'm upgrading to four stars for the quick customer service and the fact that the bit worked perfectly on another screw. I attempted to remove a pickguard screw from a guitar with it. These aren't made of hard metal or stainless steel, and they'll easily corrode. The cutting end of the smallest bit, on the other hand, broke very quickly in this case, and the task was not completed. I understand that such things happen, so I may adjust this depending on the seller's response. Also - The guitar is damaged as a result of the tip shearing off like that. Thankfully, the damaged area is under the pickguard, as it skipped off to the side of the screw in that direction rather than out into the visible part of the guitar, or I would be even more enraged.
