TIPS: 1. Hand drills and bench drills can be used to drill holes in stainless steel. A hand drill can be used to drill a board within 1mm, and a bench drill can be used to drill a board of 2-3mm. 2. When opening the stainless steel, the speed cannot be fast, a few hundred revolutions are just right. 3. It is best to inject water or cutting fluid for cooling during processing, which can effectively prolong the service life of the drill bit.
