Makita B-35097 Impact Gold Ultra-Magnetic Torsion Insert Bit Holder

Good

I find the low star reviews that's getting sorted to the top rather unfair. This is not a replacement for drilling pilot holes, you need self tapping screws and you really should drill pilot holes in hard wood. It also won't compensate for terrible screw drive types that tend to cam out and strip like the traditional slot and cross drives, get Pozidriv or Torx or Robertson or even the new Phillips Velocity drives, anything but the old Phillips really. Finally, overdriving can be compensated with settings on your impact driver and trigger control and the bit holder prevents you for sinking the screw into wood too much anyways. I wouldn't use this for fine woodworking where I need to get it exactly flush every single time.What it does do is hold on to both your bit and the screw very securely so you can drive one-handed in either direction, so you don't have to spent extra on premium screws that have such a feature, like the Velocity screws. I had no problem removing counter sunk screws with it. I couldn't shake the screw off running my driver at full speed, so the magnet is plenty strong. It is by far the best bit holder I've tried. The price is also cheap enough that I just bought a few for the most common bits I need so I don't have to constantly swapping bits, which does get annoying as it hold onto the bits very tightly. But that is a good thing as bit tend to get pulled off typical magnetic holder on the more securely fit drive types.

I purchased this bit holder for use in building a fishing dock on a small pond, and this tool worked well for me. Using this tool with a T25 bit in a Bosch 12-volt driver, I installed almost 400 screws (9 X 2-1/2 inch) that attach pine deck boards to the dock framework. The main advantage provided by this bit holder is the magnetic collar that holds each screw in position.To use the holder, it is first inserted into the hex collet (or chuck) on the driver tool. The blue sleeve is then removed from the bit holder, to allow insertion of the appropriate driver bit. It does take a little force to pull off the blue sleeve, but that just tells me that it's not at risk of falling off while in use.This bit holder works with the short style (1" long) bits, as longer bits would position the screw head too far away from the magnetic collar. There is a small retaining ring inside this bit holder that provides a very strong grip on the bit that is inserted. In fact, it took quite a bit of force for me to remove the 1" long bit when I needed to briefly change sizes.This holder does a good job of keeping the screw from falling off, but it is best suited for driving screws into pre-drilled pilot holes. I did begin by using it to drive screws without pilot holes, but it does not hold the screw securely enough to do that easily. I found it better to take a few minutes to drill "starter" pilot holes, about 1/2" deep.Also, it's is easy to accidentally overdrive screws in soft wood, as the magnetic collar covers the screw head as it seats into the wood. Of course that's not as critical on a fishing dock as it can be on some applications. Several times I found myself popping off the blue sleeve so that I could see the screw head and fine-tune the driven depth. A drill driver with an adjustable clutch might do a better job of controlling driven depth, as long as the hardness of the target material is fairly consistent.This bit holder may not be right for every application, but I find it to be a time saver and a great value at this price.

Works great bit holder really holds the bits you won't get bit pulled out by screw heads like some magnetic bit holders. The magnetic sleeve pulls off early to either change bit or get into a tight spot where the magnetic sleeve just won't fit. I bought this because I have to hold cabinet doors with one hand and impact screw in with the other and was having a hard time keeping the screw on the bit would fall off the second you bummped the drill. This thing tho omg does it really hold the screws you can shake the drill all over and the screw will not fall off the bit makes my job 100 times easier. Ignore the bad review most are just for the bit holder and I feel like half of them don't even know what this is actually for or use the magnetic sleeve and they just wanted a bit holder. The bits are a little had to pull out but not like the one bad review stated I don't think he knew you can pull off the whole plastic sleeve. The magnetic sleeve will only work with 1 inch bits but it will hold any length of bit if need be you just won't be using the magnetic sleeve with any bits longer than 1 inch. Been using it with milwaukee 1" povi drive bits and dewalt 1" phillips bit both fit and work great with this.
