I bought a kit from an electronics store a couple of months ago to open up another device for cleaning and it has a lot of different tools. It has the T6 but no "TR6" however the T6 (and all the other "T-style" drivers) in there has the little circle-shaped divot at the top/end. Does that make it a TR6? Sorry for my ignorance on the subject.
All Torx drivers have T sizes, such as T6, T25, etc., corresponding to a screw size.
This does not tell you whether it is a standard Torx driver or a special driver with a bore hole that is variously called a Security Torx, Tamper Resistant Torx or Tamper Proof Torx driver.
All manufacturers will use one of those names to describe these special drivers and some will also use a designation. Wiha uses T6s, the s standing for Security. Some manufacturers use TR6, the TR standing for Tamper Resistant. Some use neither. PB Swiss will simply say that a driver is a Tamper Proof T6. In other words, the prefix TR is neither “official” nor universal.
Having watched all the videos, it appears that the only Security Torx driver you need is a T6. If your driver has a bore hole, it is probably a Security driver. There is no other reason for the bore hole. Maybe drop into a place that sells tools to confirm?
David Gewirtz, in his video, used what he called TR drivers for everything. It is quite possible that he was using Security drivers on standard screws.
Apropos of nothing...
As I understand it, you are in Japan. There are some really good makers of hand tools there
