Professional 122mm diamond core drill bit with laser-welded segments for dry and wet drilling in reinforced concrete, granite, and masonry. Features hexagonal 1-1/4" thread, soft cobalt layer, and 430mm crown length for precision hole creation.
The YATO Diamond Core Drill Bit 122mm (Model YT-60377) is a professional-grade drilling solution designed for precision hole creation in reinforced concrete, concrete, granite, silicate brick, and porous ceramics. This laser-welded crown drill bit features advanced diamond segments with a soft cobalt layer that enables efficient drilling both with and without a tripod, making it ideal for demanding construction and renovation projects. The bit is engineered for non-hammered operation and supports both dry and wet drilling applications, ensuring versatility across various job site conditions.
Featuring a 1-1/4" (32.0 mm) hexagonal thread size compatible with all standard market tools, this 122mm diameter drill bit delivers exceptional performance with a maximum linear velocity of 80 m/s and can achieve drilling depths up to 400mm. The laser-welded segments are specifically engineered to resist overheating caused by cutting reinforcing bars, even during dry operations, while the soft cobalt layer exposes the diamond cutting surface progressively for optimal performance. With a total crown length of 430mm, this drill bit is perfect for electrical box installations, ceiling drilling for pipes and cables, installation of cable routes, and ventilation duct work.
Manufactured by YATO under the GRD series and compatible with diamond drilling rigs such as the YT-81980, this professional tool combines durability with precision engineering. The bit's increased resistance to high temperatures, friction, and mechanical damage ensures long-lasting performance even in the most challenging drilling conditions. Whether you're working on new construction, renovation projects, or specialized drilling applications, this diamond core drill bit delivers the reliability and precision that professional contractors demand.
