RUKO SPB-DIN1869-3.0mm-Série-2 broca helicoidal extra longa HSS-G 3,0 mm

For machinists and metalworkers who need extra reach in deep drilling tasks, the RUKO SPB-DIN1869-3.0mm-Serie-2 is an extra long twist drill bit with a 3.0 mm cutting diameter. Ground from solid HSS-G high speed steel, it delivers reliable performance in steel, cast iron, non-ferrous metals, plastics, and wood. The 125 mm total length and 80 mm flute length provide the extension needed for hard-to-reach holes, while the 118° conical point and right-hand cutting direction ensure clean, accurate starts.

Why choose it

The extra long design reaches deep into workpieces where standard drill bits cannot. Ground flutes and a precise 118° point reduce wandering and improve hole quality. HSS-G steel offers a good balance of hardness and toughness for everyday drilling in common materials.

Ideal use cases

• Drilling deep holes in steel and cast iron
• Reaching through fixtures or jigs
• Creating pilot holes in thick sections
• General workshop and maintenance tasks

Good to know

This drill bit is supplied as a single unit. For best results, use appropriate cutting fluid when drilling metals and reduce speed when exiting the hole to avoid breakout.
