I'm recommending you use these on hand tools mate, I always do as they're much stronger. I have never had an impact socket break on me using compressed air tools let alone hand tools. Also when using a cracking bar ALWAYS pull upwards never push downwards in case it slips. Saves getting a face full of car or concrete.

ps. My rechargeable impact wrench is SIP brand.
