SS304 and SS316 self drilling screw just can drill Aluminum Alloy sheet
It should be slowly when use the electrodrill.otherwise,the temperature will high cause aluminum scrap will dissolve easily which will stick to the thread of the self drilling screw and cause the aluminum scrap can't be discharged easily then will occur can't drill and broken end if use the electrodrill faster.
