I've done it too. The hollow tipped bit is, obviously, weaker.
Torx sockets are one of those places where I absolutely could not abandon truck-branded tools, even if I left the field professionally.
I've stripped every last trace of the torx head (leaving a round hole) on multiple fasteners using an impact to try and break them loose as a last resort, and my "Heavy duty removal" Snap-On T25 socket (with the gold-colored bit) still looks brand new, which is saying something, since Volvos are pretty much 50% assembled with a 10mm, 13mm, and 18mm bolts. The other half is held together with T25 torx screws.
I was using a set of Matco's Silver-Eagle (their version of Blue Point) bits for a while, but broke one every week or two being careful.
I bought the "HD Removal" Snap-On bits on eBay for a damn good price, and haven't looked back. I think I've broken one bit in over a year.
