Just received a set of top quality torx drivers from Wiha. I got an 11 piece kit that is packed in a metal box that has a spring loaded snap closer. The drivers are torx 3,4,5,6,7,8,9,10,15,20. There are also 3 phillips 00,0,1 and 3 straight edge 2.0, 3.0, 4.0. A handle with a collet type ring to hold the drivers is also included. Each driver is double ended, except for the t-3,t-4, and t-5, and are 4.75" long. The rod just slides into the handle and you tighten down the collet ring and go to town. The stell is a chrome-vandium-moly steel and these are manufactured in W. Germany. These are without a doubt the BEST drivers I have ever used! The tork bits in the BM offering will twist if you look at them mean, especially the t-6. I can't tell you how many I have twisted on tight screws. Not these those as they are hardened to take the pressure. I expect that these will be used by my son, his son and so forth. They ain't cheap, but QUALITY usually isn't!
