RUKO HSS type N twist drill bit Ø 6.5 mm DIN 338, high precision and durability.

The Ruko-2144065 twist drill bit, with a diameter of 6.5 mm, is a high-performance tool designed to deliver exceptional performance in a wide variety of common materials. Its high-speed steel (HSS) construction ensures high concentricity and rotational accuracy, making it an ideal choice for jobs requiring precision. The drill bit features a tapered point grinding with a split point, conforming to DIN 1412 C, which facilitates penetration into the material and reduces initial slippage.

With a cutting angle of 118 degrees and a spiral angle of 20-30 degrees, this drill bit is optimized for efficient and effective cutting. Its bright surface not only enhances durability but also minimizes friction during use.
