Frequently Asked Questions (FAQs)
1. Why is stainless steel so hard to drill?
Drilling stainless steel can be challenging due to the risk of work hardening. If the cutting speed is too high and the feed is too slow, the heat generated can cause the material to harden, making it more difficult to cut.
2. What is the trick to drilling stainless steel?
When drilling stainless steel, it is important to use lubrication. Lubrication helps reduce heat and friction, improving drilling performance and extending the life of the drill bit. Apply a lubricant specifically formulated for stainless steel, such as cutting oil or a lubricating paste, before starting the drilling process.
3. Is it better to drill stainless steel fast or slow?
When drilling stainless steel, it is better to use sharp bits, low RPM, higher cutting pressure (feed), and plenty of lube/coolant. High RPM can cause the drill bits to burn out quickly, so a slower drilling speed is recommended.
