The Ruko-814040 twist drill bit is designed to deliver exceptional performance in demanding drilling applications. With a 4 mm diameter, this tool features a 118° cutting angle and a 20-30° spiral angle, optimizing its penetration capacity in various materials. Made from solid TC K 20 steel and with a cylindrical shank, this drill bit is ideal for working with high-strength steels, as well as other abrasive metals and plastics.
The TiAlN (titanium aluminum nitride) coating not only provides greater durability but also increases cutting performance by 50%, resulting in a longer tool life.
Its right-hand cutting design allows for efficient and precise drilling, adapting to a wide variety of materials, from CrNi steels to titanium alloys.
