RUKO HSS type N twist drill bit Ø 8 mm, DIN 338, high precision and durability.

The Ruko-2144080 (DIN 338 type N) high-speed (HSS) twist drill bit with an 8 mm diameter is a precision tool designed to deliver exceptional performance in a wide variety of materials. Its high concentricity and rotational accuracy ensure optimal results with every hole, while its tapered, split-point design, compliant with DIN 1412 C, facilitates penetration into the material, reducing slippage and improving cutting efficiency.

With a cutting angle of 118 degrees and a spiral angle of 20-30 degrees, this drill bit is optimized for efficient and fast cutting. Its bright surface not only provides an attractive aesthetic but also contributes to reduced friction during use.
