INTOO Drill Bit Set 21 Piece 1/16"-1/2" Quick Change Impact Driver Bit Set

EVER SINCE I GOT MY IMPACT DRIVER I BEEN LOOKING FOR A SET OF DRILL BITS SO I CAN ALSO USE MY DRIVER AS A DRILL. I CHOOSE THIS SET BECAUSE IT LOOKS GOOD AND THE PRICE IS REASONABLE. IT ARRIVED ON TIME. IT WAS GOOD, SOLID FEEL AND VERY WELL MADE. I USED A FEW OF THE SET FOR A FEW TIME ON METAL AND WAS HAPPY , I DON'T KNOW HOW LONG THEY LAST. ONLY TIME CAN TELL. BUT SO FAR SO GOOD. NO COMPLAIN AT ALL.

I like that these drills have a pin that secures it to the shank. I've had other sets that were merely glued together, and under high torque simple disconnect (shank free spins around drill). The tips are sharp, and I expect these to work as intended. I'm trying to buy more drill bits with shanks - because they tend to perform better in my battery operated drills with keyless chucks. Drill bits are an expendable item for me; I'm not rigged up to sharpen bits, so when they get dull - they get replaced. These are cheap enough that I can re-buy as needed.

I bought this set of drill bits so I could have my own instead of asking my husband to borrow his every time I want to do a project. These bits are perfect for my cordless drill and there is a size for any job you need to do. I have to hide them because my husband likes them too even though he has his own set and I know if I let him use them without my knowledge, he will end up losing all of MY bits.... lol. The case is an added bonus for keeping everything organized.

These bits work, they drill holes, are easy to put into your drill, and then take out. The only issue is (if you're using a standard non chuck drill) they have a hard time exiting the holes you just drilled when you bring your driver up. They tend to stay in the holes. It's easy enough to hand pull them out and replace in the driver. So, you really only want to use them in something like an impact driver, or a drill with a chuck that locks them into place.

They flex easily and my 3/32 broke of in the pilot hole I was drilling to install child safety locks on my cabinets. I was 3/4's into the hole when it just started spinning. I reversed directions to back it out when I saw that the rest of the bit just stayed in the hole. I could not get it out so had to start at a new location with a smaller bit. I will update my rating if I here from the company.

Fast delivery, item exactly as described.. the drill bit set comes in a drill index which is a great aid for storing the hex drive bits separate from straight shank bits. Durability and usability (staying sharp) has not been a problem with these bits.

Two broke within one day of use. I was drilling into redwood and it became really brittle once it heats up. I was using it normally too. I’m disappointed at the quality. My previous set last me years doing the same thing.

Purchased the INTOO Drill Bit Set 13 Piece 1/16"-1/4" Quick Change Impact Driver Bit Set for general use around the house. The set arrived in the standard factory packing with no signs of damage.PROS• The ¼-inch hex bit shanks fit well and lock securely in all of our quick change hex chucks.• Bits appear sharp but have not tested them on any mild steel.• Bits are pinned in the shanks which should prevent them from separating from the shank during use.• Bit size is clearly stamped on the shank of each bit for easy size identification.CONS• Chucked each bit in our commercial quality drill press (that has very little spindle runout) to check the wobble (runout) at the point of each bit. The 1/16, 5/64, and 9/64 bits all had very noticeable wobble. The rest of the bits were acceptable.• No case, just a simple plastic holder that is clearly marked with each bit size (as shown on web age). Pretty standard for a small drill bit set in this price range.Recommend you consider this product if you are interested in a reasonably priced drill bit set for general use around the house (especially if you purchase the set during a Lightening Deal). Just don’t plan on using these bits for any high accuracy drilling. But who buys ¼-inch hex shank bits and uses them in a locking hex chuck for high accuracy drilling anyway!This product was not provided as a sample for this review, so none of these comments are influenced in any way by the seller.
