KORR Tools KIBPP021 45pc Impact Torsion Screwdriver Bit Set Phillips Bits, Square Recess Bits, Torx Bits and Slot Bits

The bits are not of really good quality they break easily, and the storage box tabs break easily as well so you end up with your bits all mixed up or lost

very cheaply made/stick with name brand...

This set of 45 bits and adapters comes in a nice plastic storage case that locks shut and fits easily in a toolbox or workbench for quick access. These bits are different from any I've used in the past since they have a torsion part that allows the shaft to flex a little without stripping the bit. That seems to work better on the longer bits, I didn't notice any flex with the shorter ones but they could be flexing a little.The kit is a mixture of philips, torx, flathead, and square bits, pretty much anything you would need except for hex bits or other specialty bits that some electronics and hardware companies use. A few adapters are included. The 1/4 inch drive extender can be used for any of the bits in the package or other bits you may have, and the 1/4 and 3/8 socket adapters allow you to use normal sockets with your impact driver. Overall, it's a very nice kit for the price. I've put a decent amount of stress on the bits testing them out and none have stripped a screw or the bit, but I am also being careful not to damage the bits as I always do. This set should last many years, it's better quality than I was expecting and I really like the storage case to keep everything organized. You will notice it looks like one bit is missing near the bottom left, but that's normal. It's a 45 piece set and there are 45 bits with the one slot open. You could put one of your own bits there if you wanted, like the one that comes with your impact driver or drill tool.

These are good quality bits. You get a lot of variety and the bits feel sturdy. I have been using them in my impact drill, and they have been withstanding the abuse. It's always good to have a variety of bits in your toolbox, and this is an affordable choice. Sometimes you get more bits than you need, or some that you don't. However, it's always good to have them laying around in case you need them. It comes in a nice study case, and holds them in place well.

I'm using these in a Ryobi 18V brushless impact and they fit the chuck just fine. The auto-release mechanism on the Ryobi works with these bits without issue. While the narrow shaft looks a little odd, the bits hold well and seem to stay in place better than using normal driving bits.I've used the Bosch Impact Tough driving set and this is just about identical in how it feels.The case is fine and easy to open. The bits are a bit of a struggle to get unclipped but if they were any easier they'd fall out when you toss your bag around. So it's all good.The Bosch set is easier to tell the bit size. On this set the bit sizes are stamped lightly into the metal. I just grab whatever bit looks like it will fit but if you can't recognize a T20 and need to look at the label, the stamped size makes it a challenge.

Norske Tools KORR 45 pcs Impact Torsion Screwdriver Bit SetMy husband has said that above for years and, if you're using an impact driver, it certainly seems to be true. Impact-type bit sets have become much more common in the past several years but, just because they have that characteristic round shaft body, doesn't mean they will actually hold up. My husband used three different bit types over the past two weekends to both drive screws and remove screws that had been in place for over 15 years. He said he didn't go easy on them but only had one bit break and that was a Phillips drive bit driving a 1/4" x 2-1/4" concrete anchor screw. From experience, driving concrete screws causes more bit failures than any other task. Although he hasn't had the opportunity to try all of the bit types in the set, he's impressed at how well the Torx and Phillips bits held up. Highly recommend.

This is the type of set that is worth gold to a new homeowner or someone getting started in DIY. It has a relatively comprehensive array of bits in different shapes, a quick change driver, and duplicates of some common sizes. The metal is also strong and so far has resisted stripping well. It is a little higher quality than some similar sets, though that makes sense for the price. Still, it is a good value.The case is a little wonky in that it arrived with the bits all over the place and some hardly fit. Still, in practice it has held the bits in place well enough. This is an area that some other brands do better, particularly those that hold more securely and rotate out for easy removal.Overall, an excellent set for anyone getting started or like me who has lost a lot of them. I would highly recommend it as a gift, too.

I do wish this set came with some standard hex bits, but the bits it does come with are good quality. For my fairly light hobby woodworking and home repair use, they seem on par with my big-brand-name set, at a slight lower price.They fit well in my green-brand impact driver, and I haven't stripped one out yet.
