I use these to mortise wooden knife handles. I trim off most of the uncut section of the bit to make them stiffer as I don’t need the whole length. They are ok. Several of the bits in the package were bent to the point they were not usable, but others were ok and they were cheap, so just keep your expectations kind of low.

Well worth the price, searched for deals all over this was the best one by far. Great length and sharpness overall. Worked well for drilling holes in order to install internet to homes. Did have one or two break due to extreme cold and pressure, which could be chalked up to being an operator error. Highly recommend these drill bits if you’re looking for quality and quantity products.
