Latest Patents

Niklas Ahlén holds a patent for a drill bit insert designed for rock drilling. This insert features a sintered cemented carbide body that includes a hard phase of tungsten carbide (WC) and a binder phase. The cemented carbide composition consists of 5.0-7.0 wt % Co, 0.10-0.35 wt % Cr, and a Cr/Co weight ratio of 0.015-0.058. The hardness of the cemented carbide body ranges from 1520-1660 Hv30, with a toughness of K1≥10.0, both measured in the bulk at the center of the longitudinal axis through the center of the insert or ≥5 mm from any surface of the insert. Additionally, the insert exhibits a surface toughness K1≥12.0, measured at 0.5 mm below the surface of the body in a transverse direction to the longitudinal axis. The invention also encompasses a drill bit that incorporates this insert and its application for drilling purposes.
