Drilling stainless steel sheet requires the use of proper tools and techniques. Here are some common methods:
Choose the right drill bit: Drilling holes requires the use of high-speed steel or cobalt steel drill bits. These drill bits are more wear-resistant than regular carbon steel drill bits and can handle the hardness of stainless steel better.
Use coolant: During the drilling process, stainless steel will generate high temperatures, which can easily lead to drill bit wear and work piece deformation. Therefore, it is best to use coolant when drilling to lower temperatures, reduce friction, and extend tool life.
Adjust drilling speed and feed rate: When drilling stainless steel, it is often necessary to reduce the drilling speed and feed rate to reduce heat and friction and avoid overheating and damage to the drill bit.
Use proper drilling techniques: When drilling, you can use a step-by-step drilling method, that is, use a smaller diameter drill bit to pre-drill the hole, and then gradually use increasing diameter drill bits to enlarge the hole diameter.
Secure the workpiece: During the drilling process, be sure to secure the stainless steel sheet to prevent it from moving or shaking, resulting in inaccurate drilling positions or damage to the tool.
Remove chips in time: During the drilling process, the chips generated by drilling should be removed in time to ensure the quality of drilling and prevent the chips from clogging the hole or damaging the tool.
Be safe: When drilling, be sure to wear appropriate personal protective equipment, such as safety glasses and gloves, to prevent accidental injuries.
