Product Description

From the Manufacturer

Pro Grabit 3 piece extractor kit works on damaged screws and broken bolts from as small as No. 4 screw to as large as 5/16 in. bolt. Quickly and easily removes most damaged screws such as Hex, Phillips, Torx, Square Drive; sizes No.4 - 14 from wood, plastic or metal up to 3 inches in length. Two-step drill bit and extractor in one tool extracts broken bolts and damaged screws fast; use in reverse only when drilling and extracting with reversible hand held power drill. Can drill up to grade 8 or 10.9 class fasteners; extracts bolt sizes No. 10- 5/16 in. (5mm - 10mm). Serrated extracting end of tool results in greater torque for hard to remove bolts and screws. No bolt preparation required. Professional grade multi-purpose extractors compatible with "quick-connect" chuck systems or chucked directly into drill. Good for multiple extractions with single tool.

5.0 out of 5 stars A new solution to an old problem January 6, 2011
Verified Purchase
In order to judge a product of this type, finding out that it works (for me) isn't good enough. Finding out that it works when other extractors fail is what makes the difference. I've used a variety of other extractors over the years, and by variety, I really mean different sizes or brands of extractors that are essentially of the same design. One problem I had was never having the right size. The other was that I often ended up drilling out the screw heads after giving up, and then untwisting what was left after disassembly.

Traditional screw extractors have many issues. They have a gradual taper, making it difficult for them to grab after drilling out a shallow hole. They require something to hammer them in place, even when clearance may present an obstacle. Likewise, drilling is more of a constraint with traditional bits in a quick change chuck than with the Aldens, which are shorter. Finally, traditional extractors need something to turn them, and having the right handle from a die set is not always going to be the situation.

The Alden set let me extract several cap head screws that an Irwin Tools 53545 Spiral Flute Screw Extractors, 6 Piece Set not only failed to extract, but had also made the problem worse. On one slightly stripped cap head screw, a minimal amount of boring with one end of an Alden extractor let me flip the extractor over and back out the screw easily. On one that had been predrilled for another extractor, I didn't expect the Alden to work. But I somehow managed to get it to bite in a hole much larger than it was designed for when I tilted it to the side.

All in all, I like the design much better than anything I've used in the past.

3.0 out of 5 stars Grabit works, but... July 2, 2008
By Roger
I used the Pro Grabit to remove 2 1/2" screws that have secured my deck for 20 years and have been intractable for many years. It worked well for a several screws, but then the extractors broke. Reading the warnings in the detailed instructions, I find: "Tool can be compromised if extracting large screws exceeding 2 inches in length and/or have aggressive threads".

4.0 out of 5 stars Not for heavy duty screws or bolts... June 29, 2012
This set is great for removing small sheet metal and wood screws that have stripped out/corroded over time. I bought this set some time ago and it sat in my tool box unused for about 3 months until I had some automotive trim that needed to be removed so I could pull and clean the carpeting. I had a total of 3 screws that were corroded that easily stripped when trying to remove them along with my door sill trim on my 20+ year old truck. I actually had just got done drilling out some 10mm grade 8 seat retention bolts that seized up with a set of cobalt drill bits and was really sickened at the fact of doing more drilling. However, I remembered that I purchased these and decided to give them a try despite not expecting much from the set. I started with the smallest bit possible and it ended up being all that I needed to remove the 3 stripped out screws, making my life a lot easier. I had the three out in a matter of just a few minutes.

Remember, just like drilling anything out, start with the smallest size possible and work your way up only if you have to. Don't expect these to bail you out on seized bolts or screws but rather light to medium duty screws/bolts that have lost their head. Two days ago I was a beginner at drilling. After drilling for about 3 hours on 4 grade 8 seized up bolts I now consider myself well seasoned. Not that I want to go through it again. But, it is definitely nice to see when a product like this comes around to perhaps make things much easier/less time consuming on the user.

I also purchased a set of hammer in screw extractors that I tried on a few odds and ends and couldn't get the darned things to ever bite. These are much nicer and compliment my 18V Makita drill driver very nicely. It's not something you'd use daily, but it is definitely something worth while to have and at least give it a shot when the time may come.

5.0 out of 5 stars Grabit Pro- Needed in all tool kits! April 30, 2008
Using the Pro Grabit couldn't be easier. I stripped normal sized screws when installing floorboards and digging them out would have caused a lot of damage. Using the Pro Grabit as instructed I was able to quickly and easily remove even screws that I had stripped to a round hole!

I think the other reviewer should have bought the 4 piece kit since it has the largest Grabit (No 10 or 3/8) and would have taken care of his problem. I have also used the 4 piece (which is the same as the 3 piece but with the extra largest size Grabit bit). Same Made in the USA craftsmanship and nice little case to keep them all together.

Overall a perfect item to have around when you get a caught with a stripped screw or bolt. I'd recommend having one in every handyman's toolkit.

5.0 out of 5 stars Amazing December 27, 2013
Verified Purchase
A friend of mine calls these things "magical" and even says that we have to try to limit their use so that we can preserve the magical qualities. A big time saver whenever a screw is stuck. There are 3 different sizes for different size screws. I usually try to start with the smallest and go up a size if that one doesn't work. Make sure to follow the directions and have a light touch, but once I got the hang of it I've never not been able to pull out a stripped screw. The case is small and tight and I keep a set in all of my toolboxes just in case.
