for Torx Bit, 30 Pcs T10 Torx Screwdriver Star Bit Set, Length 25mm Precision Security Bits, (6.3 mm) 1/4" Hex Drive Hex Shank Bits Set for Electronic Repair Tools

I needed some of these as the one i had broke on a job i am doing. These have proved as good as the one that came with the screws however not great. In about 40 screws my impact driver goes through another one of them. I do not necessarily think it is an issue with the bits but the thin blades (they need to be thin to fit the screws) as they just break off after 40 or so screws. Glad they come in bulk as i may need them all.For note i do have the same problem with Philips heads but they generally last longer say 100 or 200 screws
