RUKO SPB-DIN338-HSS-G-Kreuz-18,0mm spiraalboor

For machinists and metalworkers who need precise, clean holes in tough materials, the RUKO SPB-DIN338-HSS-G-Kreuz-18.0mm twist drill bit delivers reliable performance. Ground from solid high-speed steel (HSS-G) to DIN 338 standards, this 18.0 mm bit features a 135° split point that self-centers and reduces walking, while the bright ground finish and right-hand spiral flutes ensure excellent chip removal. With a total length of 198 mm and a working length of 130 mm, it is suitable for drilling steel, cast iron, non-ferrous metals, and plastics. The cylindrical shank fits standard drill chucks, and the h8 tolerance guarantees consistent diameter accuracy.

Why choose it

The split point design eliminates the need for center punching, saving time and improving hole accuracy. The HSS-G material provides a good balance of hardness and toughness, while the bright finish reduces friction and heat buildup. This bit is ideal for both manual and machine drilling in a workshop environment.

Ideal use cases

• Drilling precise holes in steel plates and profiles
• Creating clean holes in cast iron components
• Working with non-ferrous metals like aluminum and brass
• Drilling plastics without melting or cracking

Good to know

For best results, use appropriate cutting fluid when drilling steel and ensure the drill is held securely. The cylindrical shank fits standard three-jaw chucks up to 13 mm capacity, but a reducing sleeve may be needed for larger chucks. Always follow safety guidelines and wear eye protection.
