Latest company news about how to drill stainless steel ?

It can be more difficult to drill stainless steel than softer materials, because stainless steel is harder and heat resistant. Follow these steps to successfully drill stainless steel:

Materials you'll need:

  1. Workpieces made of stainless steel
  2. Drill bits for stainless steel
  3. Drill press or handheld drilling
  4. Lubricant (cutting oil or oil)
  5. Safety glasses and ear protectors
  6. Clamps or vises (if drilling with the hand)

Steps:

  1. How to Choose the Right Drill Bit Use a high quality drill bit designed specifically for drilling stainless steel. The best drill bits to use are carbide or cobalt as they are hard and can handle the stainless steel's hardness. The drill bit must be in good shape and sharp.

  2. Secure your Workpiece: When using a handheld drilling device, secure the stainless steel piece using clamps or vise. This will ensure accuracy and prevent the workpiece moving during drilling.

  3. Safety precautions: Wear safety glasses and ear protection if needed to protect your vision. When drilling stainless steel, it can produce a lot heat and noise.

  4. Lubricate Area: Apply an lubricant to the area you plan to drill, such as oil or cutting fluid. This lubricant helps reduce heat and friction when drilling.

  5. Choose the Right Speed and Pressure: Set your drill press to low-medium speed. When using a hand-held drill, begin at a lower speed and increase it gradually as required. To avoid overheating of the drill bit, apply even and steady pressure.

  6. Optional Pilot Hole: When drilling larger holes, it is a good idea to drill a smaller hole first. This will help guide the drill bit, and lessen the chances of it wandering.

  7. Drill Slowly: Start drilling slowly and let the bit do the job. Do not force the drill bit through stainless steel. This can cause it to overheat and break. Apply consistent light to moderate pressure.

  8. Remove Chips: Withdraw the drill bit periodically to remove any chips. This will prevent the drill bit from becoming overheated and dull.

  9. Drill the hole: Continue to drill until you have the desired hole. Take your time and be patient, especially when working with thicker stainless.

  10. Deburring You may have to remove sharp burrs and rough edges after drilling. This can be done with a deburring file or tool.

  11. Remove any cutting fluid or debris from the workpiece.

Drilling stainless steel takes patience and the correct tools. Use the right lubrication and speed, while maintaining the correct pressure, to drill clean holes in stainless steel.
