RUKO 26mm HSS hollow drill bit with Weldon shank for multi-layers.

The Ruko-108456 hollow core drill bit is designed to deliver exceptional performance when drilling through multiple layers of material in a single operation. With a diameter of 26 mm and a depth of 55 mm, this tool is ideal for industrial applications requiring precision and efficiency. Its high-speed steel (HSS) construction and CBN grinding ensure superior durability and a clean cut, minimizing wear during use.

The special spiral geometry, featuring three cutting edges, provides optimal stability during the drilling process. This not only improves the finish quality but also prevents breakage of the cutting edges, even under overload or chip pressure conditions.
