I bought these when I bought my new buggy, built it and then had a bad snowmobile accident over the winter and wont beable to make the races this year so have decided to sell my rc car stuff instead of letting it rust, and I am just going to fly my planes. I have only used this set to built one buggy and then tear it down a week ago to sell it, the handle twist's on the top to increase how much torque is put to the bit that way all the screws and installed with the same amount of torque and you don't strip anything, there is two different size handles for different amount of torque. The bit sizes are .05mm, 1.5mm, 1/16", 5/64", 3/32", 2.5mm, 3mm. This will cost you $58.99 I will sell for $40 shipped lower 48, all bits and handles are in new shape there is nothing wrong with it
