DRILL BITS TAPERED STEP DRILL 4-39 TYTAN-3EL.

Producer: MASTIFF

Ground high-speed steel (HSS) drills with a titanium coating drill the thinnest sheets without pre-drilling, no burrs, no chips sticking to the drill bit.

They are mainly used for the processing of non-ferrous metals, thin-walled steel sheets and plastics.

Each drill is numbered. It is perfectly legible, thanks to which we can easily drill a hole of the diameter we are interested in.

They are used in sheet metal work, locksmithing, installation industry, etc.
