RUKO SPB-TX DIN338 HSS-G 8,0mm kierrepora ristihiomalla

The RUKO SPB-TX twist drill bit is engineered for precision and efficiency in metalworking. Its split point (Kreuzschliff) geometry sets it apart from standard drill bits, allowing for self-centering starts without a center punch and reducing axial force during drilling. Manufactured to DIN 338 standards from high-speed steel (HSS-G) with ground flutes, this 8.0 mm bit delivers clean, accurate holes in a variety of materials.

Highlights

• Split point tip for self-centering and reduced walking
• Ground flutes for excellent chip evacuation
• 135° point angle optimized for metal drilling
• Bright, uncoated finish for general-purpose use
• h8 shank tolerance for secure chuck grip

In daily use

Whether you're working on steel, cast iron, non-ferrous metals, or plastics, this drill bit performs reliably in hand drills, pillar drills, and automatic machines. The cylindrical shank fits standard chucks, and the 75 mm working length provides ample reach for most tasks. Its robust HSS-G construction ensures long service life under proper cutting conditions.
