RUKO HSS type N twist drill bit Ø 5.25 mm - DIN 338, high precision and durability.

The Ruko-21440525 twist drill (DIN 338 type N) is a high-performance tool designed to deliver superior performance in a wide variety of common materials. With a diameter of 5.25 mm, this drill is distinguished by its high concentricity and rotational precision, ensuring optimal results with every hole. Its design includes a tapered point grinding with a split point, in accordance with DIN 1412 C, which facilitates penetration into the material and reduces slippage.

The 118-degree cutting angle and 20-30° spiral angle allow for efficient and clean cutting, while its bright surface minimizes friction during use.
