FAQ

What is the point angle of this drill bit?

Standard DIN 338 Type N drills like this RUKO 214125 have a 118-degree point angle, suitable for general-purpose drilling in most common metals.

Is this drill bit suitable for stainless steel?

While HSS-G can drill stainless steel, it is not optimal. For better performance and tool life in stainless steel (Inox), a cobalt alloy drill bit (HSS-E or HSS-Co) is recommended.

What does the ‘Type N’ designation mean?

‘Type N’ refers to the standard flute geometry, with a helix angle around 20-30 degrees and normal web thickness, designed for drilling materials of normal tensile strength like unalloyed steels, aluminum, and cast iron.
