RUKO 18mm diameter high precision HSS-G core drill bit.

The Ruko-128018-HSS-G (Ø 18 mm) hole saw is a high-precision tool designed for drilling in a wide variety of materials. With a material thickness of up to 2.5 mm and a cutting depth of 5.0 mm, this hole saw is ideal for working with alloy steels, cast steel, non-ferrous metals, light metals, plastics, reinforced fabrics, drywall, and light construction materials. Its right-hand cutting design allows for optimal performance and increased durability, as it is resharpenable, extending its service life and reducing long-term costs.

It is important to note that this tool is not suitable for hammer drilling. It is recommended to apply light pressure when starting to drill and maintain constant pressure throughout the process.
