Karnasch - Germany

Jigsaw - core drill for magnetic drill Crown diameter: according to the selected variant Recommended drilling depth: max 55 mm Welding shank - 19 mm (3/4 ") Centering pins (see related products): For diameters 12-60mm: 20.1271 Material - HSS-XE - special high-alloy steel + DURABLUE surface treatment for longer drill life Tooth hardness: 68HRC Catalog number: 20.1313 These core drills are made of special high-alloy steel HSS-XE, which ensures extreme hardness at the tips of the teeth (up to 68 HRC), high wear resistance and long service life. Thanks to the surface treatment, it lasts longer. Few manufacturers are able to produce HSS core drills hardened in several stages. This is standard for Karnasch®. This is the only way to obtain extremely hard tooth tips (68 HRC) and a flexible and durable drill body. For HSS-XE / ASP core drills, five different drill geometries are applied for different drilling diameters and depths, so that the result is always perfect.
