About Trepanning for Stainless Steel Sheet: 1. Hand drill and bench drill can be used when trepanning for stainless steel sheet, the hand drill drill steel sheet within 1mm and the bench drill can drill 2-3mm steel sheet. 2. It is necessary to drill with low speed when trepanning for stainless steel sheet, hundreds of rpm is ok. 3. It's better to use water injection or cutting fluid coolant for cooling when drilling, which can extend prolong the using life of drill bit.
