Renting the tools is a nice option to have. Torque drivers appear to be priced at obscene level, but not really. Based on handle pattern, these appear to be customized Wera screwdrivers and they cost more to buy direct than through this program from Apple. That just feels like Snapon pricing for specialty tools. By the way, Snapon sells individual torque screwdrivers for $256. Really.
This could be targeted at corporations that have staff to do in-house repairs of their hardware. They will have the option to avoid making a trip to the Apple store and losing custody of their hardware. One of the companies where I work has such a department. They order Lenovo parts and fix the laptops on-site instead of relying on on-site field service from Lenovo.
