Metric & SAE Hex Head Allen Wrench Drill Bit Set,TEKPREM 20-Piece 1/4 inch Magnetic Tip Hex Screwdriver Bit Set with Rubber Strip and Storage Box, S2 Steel & 2 inch Long

A very complete set of strong units for effective use.

I use this specifically with my impact driver. It works great, and seems to be well made.

I recently purchased these Allen Wrench Sets, and they actually exceeded my expectations. Considering the quality and the number of wrenches included, it's an excellent value for money.The set comes with a small storage sleeve, which is a wonderful addition. It helps me keep the wrenches organized and prevents them from getting lost or misplaced. The sleeve is compact, making it easy to store.The wrenches fit snugly into their designated slots in the storage sleeve, making it effortless to keep them in order. Whenever I need a specific size, I can quickly locate it without any hassle.The compactness of the set is another notable feature. I initially bought this set as an extra for convenience, but I've been pleasantly surprised by how well it performs. The wrenches work seamlessly with both my drill and impact driver.Overall, this Allen Wrench Set is a great investment. It offers excellent value for the price, comes with a convenient storage sleeve, and is incredibly easy to keep organized and carry around. If you're in need of a reliable set of wrenches for your toolkit, I highly recommend giving this one a try.

I ordered these on amazon over others on amazon only because they're sold with a case. I'm not interested in purchasing a case separately and making sure the "3rd party" case is the correct size. The bits themselves have held up fine. I don't make my living off of these bits. Just as I wouldn't use harbor freight tools if I were a contractor, I wouldn't recommend these in the same instance. Milwaukee, Dewalt or Bosch in that order is what an electrician, carpenter or plumber should be using. If you're going to use these bits twice a month give or take, go for it. If these bits are what you'll be using to make a living, purchase Craftsman. I'm disappointed though shipping was extra. That could've either been built into the price (what I don't know wont kill me) or it should've been free. Also, one of the bits I received had a misprint on it. The number and unit of measure was smudged and slanted. I opted for the 'replace' feature amazon has on it's website and received a new set, and nothing was wrong with the replacement. I kept everything of the original set but the one defective bit and did a swap that way. If I'm not mistaken, the defective one was the '3mm' bit.

In the drill or impact-driver these bits deliver. Wide assortment of sizes in convenient organizer. So far all good and glad to have them in my toolbox.

Works very well in my impact drill

Nice bits! Have already saved significant time putting kid’s toys together by chucking one of these in a drill vs. using an Allen key. Seem like they’re high quality and should last.

The bits arrive in a small rubber strip that hold them securely, and a plastic case. Well made. Used one of the bits the day they arrived. Well worth the money.
