• Drilling large-diameter holes in steel plates and structural sections
• Creating precise holes in cast iron components
• Machining non-ferrous metals such as aluminum and brass
• General workshop drilling with Morse taper spindle machines

Good to know

The Morse taper shank (MT2) requires a matching spindle socket; no chuck is needed. The drill bit is supplied as a single piece. For best results, use appropriate cutting fluid and ensure proper alignment.
