Used the right angle attachment loads of time , never had any problem with it, always taken it to be a substantial heavy duty bit of kit. Used it with augers and drills and large and small screws. Never heard of any problems reported
Thanks John, I've used it with a max 8mm festool brad point bit and on small screws fitting cornice to kitchen cabinets so was a bit gobsmacked when it failed. Just wanted some background history before ringing TTS in Morning.
