RUKO SPB-FLS-DIN338-HSS-G-Ø20,0 mm-3FLS-puntenspiraalboor

This twist drill bit features a split point and three flutes, distinguishing it from conventional two-flute designs. The split point reduces walking and improves centring accuracy, while the third flute enhances chip evacuation and stability during drilling. Manufactured from high-speed steel (HSS-G) and ground to DIN 338 specifications, it delivers reliable performance in general-purpose drilling tasks.

Highlights

• Split point tip for precise starting without centre punching
• Three flutes for efficient chip removal and reduced clogging
• Ground from high-speed steel (HSS-G) for durability
• Conforms to DIN 338 for consistent dimensions and quality
• Suitable for steel, cast iron, non-ferrous metals, and plastics

In daily use

The 20.0 mm diameter and cylindrical shank fit standard drill chucks. The 118° point angle is suited for general-purpose drilling in a range of materials. The bright finish reduces friction and helps prevent chip adhesion. With a total length of 205 mm and a working length of 130 mm, it provides adequate reach for many applications.
