Diamond Core Drill Bit DX-HIGH SPEED PLUS D.220 mm Standard ROTHENBERGER

The DX HIGH SPEED Plus diamond core bit with a 1.1/4 inch UNC thread connection is suitable for wet and dry drilling. With a maximum usable length of 430 mm, the diamond core bit can create holes with a diameter of 220 mm. The utilization of the complete diamond segment, without loss due to neutral zones, is achieved by a cold welding process using the latest connection technology, called Space Welding. The core bit is characterized by improved starting behavior and optimal water cooling through PRISMACUT. The exact concentricity reduces wear, and the core bit is very free-cutting for a secure start in handheld operation. Space Welding: Cold welding process using the latest connection technology. Utilization of the complete diamond segment without loss due to neutral zone. PRISMACUT: Four starting lenses on the diamond segment improve starting behavior and simultaneously ensure optimal water cooling. Exact concentricity reduces wear. Very free-cutting for a secure start in handheld operation. The universal diamond core bit is, in conjunction with the RODIADRILL 160 / 200 / 500 drilling motors, ideal for wet drilling in reinforced concrete and natural and artificial stone, as well as for dry drilling in masonry, sand-lime brick, Poroton, and other lightweight materials.
