Klein Tools 33801: My Go-To 40-Piece Impact Bit Set
I’ve run plenty of bit sets into the ground, and most of them tap out long before the job does. The Klein Tools 33801 is a different story. Forty pieces, ProFlex S2 steel construction, magnetic nut drivers, and compatibility with the MODBox system – this thing was clearly designed by someone who actually swings a drill for a living. The Phillips, slotted, square, and TORX bits all seat clean and hold their edge under real impact loads. No cam-out drama, no stripping, no garbage bits rattling around in a flimsy tray. The included case keeps everything organized and ready to grab fast. Whether I’m roughing in or finishing up, this set handles the rotation without complaint. Klein built something here that earns a permanent spot in my bag – and that’s not a compliment I throw around lightly.
