The Yato YT-60377 Diamond Core Drill Bit belongs to the GRD series and is engineered for use with diamond drilling rigs such as YT-81980. It enables fast and precise drilling of holes in reinforced concrete, concrete, silicate, and ceramics, making it ideal for electrical box installation, pipe and cable passages, and ventilation duct mounting.
Laser-welded segments resist overheating caused by cutting rebar, even during dry drilling. A soft cobalt layer in the segment exposes the diamond during hand drilling, increasing efficiency without requiring a tripod. The bit offers high resistance to heat, friction, and mechanical damage.
With a crown length of 430 mm, segment size of 4 × 8 × 24 mm, and a 1-1/4″ hexagonal shank, it is compatible with most diamond drilling rigs available on the market.
