Stainless steel is a robust and versatile material used in many applications, from the automotive industry to kitchen equipment. However, machining stainless steel, especially drilling, requires precision and the right know-how. The correct drilling speed for stainless steel is crucial for achieving a clean result and preventing damage to the workpiece or the drill bit. In this article, you will learn everything you need to know about the optimal drilling speed for stainless steel, including a practical stainless steel drill speed chart.
What is a “Stainless Steel Drill Speed Chart”?
The term “Stainless Steel Drill Speed Chart” describes an overview that specifies the recommended speeds for drilling stainless steel depending on various factors such as drill bit size, material thickness, and coolant. Such a chart is an indispensable tool for anyone who works with stainless steel regularly. It helps to extend the life of the drill bits and improve the quality of the drilled holes. For the car mechanic, knowing the correct speed is particularly important, for example, to create precise drill holes for threads in engine blocks or body panels. Imagine you have to drill a threaded hole in the engine block of a classic car – precision is required! The wrong speed can quickly lead to a costly mistake here.
Drill Speed Chart for Stainless Steel
| Drill Bit Ø (mm) | Speed (RPM) (without cooling) | Speed (RPM) (with cooling) |
|---|---|---|
| 2 | 2500 | 3500 |
| 4 | 1250 | 1750 |
| 6 | 830 | 1160 |
| 8 | 625 | 875 |
| 10 | 500 | 700 |
This chart serves as a guideline. The optimal speed may vary depending on the specific application and drill bit used. It is always advisable to consult the recommendations of the drill bit manufacturer. “The right speed is the be-all and end-all when drilling stainless steel,” emphasizes Dr. Ing. Hans Müller, author of the technical book “Precision Drilling in Metalworking.”
Why is the Correct Drilling Speed So Important?
The correct drilling speed is crucial for the quality of the hole and the life of the drill bit. A speed that is too high can lead to overheating and wear of the drill bit, while a speed that is too low leads to an unclean drilling result and increased effort. In the worst case, the drill bit may even break. “A broken drill bit in an engine block can result in costly and time-consuming repairs,” explains car expert John Smith in his work “Automotive Troubleshooting Guide.”
