Diamond core bits for wet drilling

CORONA DUE 450

The traditional laser-welded diamond core bit offers excellent cutting performance and maximum safety against segment detachment, ideal for those looking for a solid, durable product, and can be re-tipped on request.

PRODUCT DESCRIPTION

Of traditional design but with laser-welded segments, this core bit has the same cutting performance as the CORONA TRE 450, but a lower drilling speed due to the absence of the spiral. It is particularly suited to customers looking for an excellent product, well protected against the risk of segment breakage thanks to laser welding. Core bits can be re-tipped on request, but only using the brazing system.
