RUKO SPB-DIN338-HSS-G-Kreuz-19,5mm σπειροειδές τρυπάνι

Drilling precise holes in tough metals can be challenging with standard bits that wander and overheat. This 19.5 mm twist drill bit solves that with a split point design that self-centers and reduces walking, while its precision-ground HSS-G construction withstands high temperatures and maintains sharpness.

Who is it for

Professionals and serious DIYers working with alloyed and unalloyed steel, cast steel, cast iron, sintered iron, malleable cast iron, non-ferrous metals, and hard plastics. Ideal for workshops, manufacturing, and maintenance tasks requiring accurate, clean holes.

Main features

• Split point (Kreuzanschliff) with 135° point angle for self-centering and reduced walking
• Precision ground from solid HSS-G high-speed steel for durability and heat resistance
• Right-hand spiral flute for efficient chip removal
• Cylindrical shank with h8 tolerance for secure chuck grip
• Bright surface finish

Tips

Use cutting fluid when drilling steel to extend bit life. For best results, drill a pilot hole with a smaller bit before using the 19.5 mm bit in thick or hard materials.
