RUKO SPF-conjunto 13 peças HSS conjunto de 13 brocas helicoidais HSS-G, 1,5-6,5 mm, DIN 338, retificadas, estojo de plástico

This 13-piece twist drill bit set from RUKO GMBH stands out with its precision-ground HSS-G steel construction, delivering reliable performance across a range of materials from steel to wood. Unlike many sets that mix quality levels, every bit here is manufactured to DIN 338 with a consistent 118° point angle and h8 shank tolerance, ensuring uniform drilling behavior and easy replacement.

Highlights

• Complete set of 13 metric sizes from 1.5 mm to 6.5 mm, covering common pilot and clearance holes
• Ground from solid HSS-G for high concentricity and long tool life
• Bright, uncoated finish reduces chip adhesion and allows easy resharpening
• Supplied in a reusable plastic cassette for organized storage and quick size identification

In daily use

The cylindrical shanks fit all standard drill chucks, and the right-hand cutting direction suits hand drills and pillar drills alike. Suitable for steel up to 900 N/mm² tensile strength, as well as cast iron, non-ferrous metals, plastics, and wood. The standard spiral flute design clears chips efficiently, while the 118° point angle provides a good balance between centering and cutting force.
