Overview

Stainless steel is a very hard material and therefore difficult to cut. Therefore, the tool steel of the twist drill should be made of HSSE-Co 5 (5% cobalt content), HSSE-Co 8 (8% cobalt content) or solid carbide

Due to the fracture susceptibility of hard tool steels, you should better use HSS drills for soft materials.

The twist drills made of HSSE-Co 5, HSSE-Co 8 or solid carbide do not neccesarily need coating . Coated drills are still ideally suited for industrial use. I.e. fast speeds (high cutting speeds), high feed rates and increased heat applications.

If you want to use a coating, e.g. to increase the tool life, it should be at least the TiAlN coating, because it has a high heat resistance. With TiAlN-coated drills, cooling is not necessarily required. In addition, they prevent cold welding on the drill.

 

Since stainless steel is a very hard material, you have to choose the right twist drill. The twist drill should belong to the application group Type H of the DIN 1386 division. Over time, however, mixed forms have been developed whose naming systems are not standardized in the DIN manual. So you will find at RUKO for the use in stainless steel the types VA, FO, UTL3000, UNI, TL3000, N and UTL.

What drill bit should I use for drilling stainless steel?

When drilling into stainless steel the choice of drill bit will ultimately determine how successful you will be. Cobalt drill bits are considered the best option due to their ability to withstand the high temperatures created when drilling harder metals. 

What drill speed should I use for drilling stainless steel?

Our advice would be to drill at as slow a speed as your power drill will allow.

Which lubricant to use when drilling? 

There are many types of drilling lubricant available including oils, sprays and pastes. A good drilling Lubricant will reduce the friction and assist in controlling temperature build up.
