Non-Planar Cutting Teeth for Drill Bit Debris Evacuation

The cutting tooth is segmented into multiple functional surfaces including cutting bevels, non-cutting bevels, and a back surface, with convex ridges dividing the cutting bevels. This segmentation allows different regions to perform specific functions: sharp cutting edges for rock cutting and beveled surfaces for debris evacuation and impact distribution.

The cutting tooth features convex ridges with curved profiles rather than flat surfaces. The convex shape of the ridges and the beveled surfaces creates curved geometries that enhance impact resistance by distributing stress and prevent balling by facilitating debris evacuation from the cutting zone.

The cutting bevels are divided by convex ridges into multiple segments, creating separate evacuation channels for debris. This segmentation prevents debris accumulation by providing multiple escape routes and reduces the formation of continuous balling patterns on the cutting tooth surfaces.

The convex ridges are positioned to actively extract and redirect debris away from the cutting zone. The geometry of the ridges and bevels creates flow paths that extract debris from between the cutting edges, preventing it from accumulating and forming balls that would wrap around the cutting faces.

The cutting tooth geometry is segmented into standardized surfaces (cutting bevels, non-cutting bevels, back surface) and convex ridges that can be manufactured using conventional processes. The segmentation creates natural channels for coolant flow and debris evacuation without requiring complex internal cooling passages or specialized manufacturing techniques.

The convex ridge geometry serves multiple functions simultaneously: it creates sharp cutting edges, provides structural support for impact resistance, and forms evacuation channels for debris and coolant. This multi-functionality achieves improved cooling and evacuation efficiency without adding separate components or complex manufacturing steps.
