TORX security drivers can be confusing. A variety of online sources indentify TORX tamper-resistent 6 point pinhole bits as being TR series and the more recent TORX 5-point pinhole bits as TS series. Based on that nominclature, this is a TORX TR10 L-Key rather than a TORX TS10 L-Key. If you are looking for the 5-point TX10, this isn't it. Customers would probably find it helpful if MCM included a picture of teh head for this tool.
MCM is a great company with a large selection of good quality products.
