Excellent guide. could not figure out the difference by looking.
It would be clearer if the displayed drawing of each bit actually said J-bit or PH-bit, and because both have 90 degree corners, maybe change the J-bit description to “have 90 degree square inside corners“ and include in the PH description “have 90 degree rounded inside corners.
Otherwise, with interpretation, your article helped me.
what size hex shaft do these smaller bits have?. i have an electric precision screw driver, for electronics. i go through the PH1 bits very quickly. i can NOT find them for sale anywhere on earth. does anybody know where to purchase these things?? and/or tell me how i should word the query. all im getting is 1/4 hex shaft results. very frustrating
4mm bit size
