            For the price, I was expecting alot more. They feel a little cheap and weren’t QC’d very well (see pic). These are replacing an old Stanley set and TBH, the quality of the less expensive Stanley tools is FAR superior to this. I’m keeping them because the EVA organization (which IS nice) and I’m sure they will work, but I won’t be buying Gearwrench again anytime soon. There are definitely nicer tools out there for the money.

              GEARWRENCH Bolt Biter Gearpack SAE/Metric Tool Set
              Always quality. The handles are large, comfortable and not slippery to the touch. It took a bit to get used to the auto-sizing of the pliers but it makes it so very convenient instead of guessing, then readjusting, on what size fits best on conventional pliers. The screwdrivers, when hit with a hammer will rotate the tip 12° to loosen any stubborn or stuck screws. An awesome idea and it really works great. The sockets fit both SAE and Metric though I only tried SAE with no problems in getting a god grip on slightly rounded bolts. A Lifetime warranty makes these tools perfect for everyday use and confidence. I highly recommend this product.

              Highest quality tools.
              This set from Gear Wrench has a variety of tools to help with removal of stubborn fasteners. It has a standard ¼” straight screwdriver as well as a #2 Phillips screwdriver. These two screwdrivers are impact drivers as well. Hold tension with them while striking the handles with a hammer. The shaft will rotate up to 12 degrees to hopefully help break loose the screw. This set also includes a 90 tooth ⅜” drive ratchet. This ratchet can operate in as low as 4 degree increments for use in tight spaces. The ratchet is to drive the bolt biter sockets. These sockets range in size from 7mm up to 16mm. They also fit some similar sized SAE fasteners. The sockets also feature six flats on the outside so that they can be driven by a wrench if the ratchet can’t fit a particular application. This set also includes 8” pliers and 10” pliers. These pliers are somewhat self adjusting as to tightening down onto a fastener. They feature an “Auto Bite” lever which encourages the jaws to move closer together. The “Auto Bite” lever can be swung away into the handle if its function needs to be disabled for a particular application. Anyone working in the trades and has to deal with rusty or rounded off fasteners can benefit from this set. I recommend the Bolt-Biter set from Gear Wrench.

              Surprising features
              This is a good tool set with innovative features. The screwdrivers have a nice large handle that makes it easy to apply torque. The bits are clean and fit well in the screw heads. The adjustable wrenches have a feature called "Auto-bite". This is a lever that when you squeeze the handle, automatically adjust the handle to the perfect setting for best grip. It is really simple but worked great! There is an 8" and a 10" wrench. The ratchet wrench has a nice long handle and the directional switch is in an easy place for your thumb to reach up and change from tighten to loosen. The sockets for the ratchet are like nothing I have seen before. The shape lets you use them on metric and standard equivalents so you only need one set. In addition, the base of the socket is hexagon which allows you to finger tighten or loosen better. I tried it out and was surprised how well it works. I really like this set.

              Comprehensive kit for stubborn bolts and screws
              This is a good kit for bolts and screws. The only thing it is missing are screw extractors. The quality is decent. The inclusion of a 1/4” ratchet is a little odd. I would have replaced it with the aforementioned screw extractors. Also, regarding the #2 Phillips impacting screwdriver (it’s a screwdriver with a striking cap that’s spring loaded so the shaft rotates 12 degrees while transferring the hammer strike to the fastener similar to an impact but with more control), the tip appears to be standard Phillips rather than JIS, meaning it won’t work on some Japanese vehicle rotor screws. Furthermore, the 1/4” flat bladed impacting screwdriver could probably be replaced with a #3 Phillips for automotive applications (though perhaps other trades would appreciate the flat blade more). Finally, the bolt biter bolt extractor sockets, which are supposed to be pretty decent, are limited to a smaller 8 piece set in this offering. Now this isn’t too big a deal because they pretty much cover the common sizes between 7mm and 16mm / 5/8 inch. But Gearwrench does offer larger sets. The pliers are a good range and seem to work very well (only time will tell). I’m not sure I’d put them on par with the industry leader but not far odd either and they will find a permanent home in most toolboxes. Their adjusting wheel feature is a nifty innovation I like quite a bit. It is at times even more convenient than the button style competitors offer. Overall high quality tools and good but in my opinion not great selection in creating this bundle.

              Just what I need
              I was looking for a tool kit to take along on our boat in case a repair needed to be done on the water. For anyone out there who has been in that position, the last thing you need is busting a knuckle on a rounded fastener or stripping a screw head while miles from shore. I love how the drivers have a spring loaded head to allow you to tap with a hammer into a stripped head. Both of the locking jaw pliers have a smart design that allows you to bite onto a fastener no matter how mangled the head is. I also like the dual sized sockets. They are clearly marked and grip firmly on the bolts or fastener heads. I have a variety of gearwrench tools at home and have had very positive experiences with them

              Love the easy-close wrenches
              For those interested in country of origin, this set was manufactured in Taiwan. Looking for some tools to assist with repairing salvaged equipment and these tools met the criteria. The bolt-biter concept on the sockets is great. Rusty heads are easy fitted into the sockets, and the drive makes quick work of breaking them out of their nuts or shafts. Took a little while to get accustomed to the easy fit of the auto-bite wrenches, but became accustomed to using my left hand easily to secure the nuts. Have not tried the screwdrivers yet, but they should work well.

              Great tool set for hard to do
              The GEARWRENCH Bolt Biter Gearpack SAE/Metric Tool Set (25-Piece) is a great set for jobs that have rusty and worn bolts, nuts and nails and it comes with tools that can be used for general purpose jobs. I used it to remove rusted nuts and was able to reuse nuts if I wanted to. The tools themselves are sturdy and strong and can handle a lot of hard work. I recommend these tools.
              The GEARWRENCH Bolt Biter Gearpack Tool Set Model # 81002
              The GEARWRENCH Bolt Biter Gearpack Tool Set Model # 81002 is a new product from the already popular GEARWRENCH brand. This set has everything you’ll need to remove rusted or stuck fasteners. Included are an 8 and 10 in. V-Jaw Tongue and Groove Pliers, a Philips and Slotted screwdriver, a 90T 3/8 ratchet, and 8 dual sized Metric and SAE extraction sockets. I like the ergonomically friendly handles on these tools and being solvent resistant for an easy cleanup. It’s an ideal set for the DIY and the Professional Tradesman. GEARWRENCH supports this product with a LIFETIME WARRANTY.
