Today’s Patent – Locating Fastener for Firearm Optic

The said invention (Locating Fastener for Firearm Optic) (US11988046B1) was invented by Anatoli Alimpievich Borissov, and patented by USPTO on October 22^nd, 2023. Currently, it stands assigned to the Cool Edge Bits.

The described invention pertains to a hydrojet rotary drill bit designed for drilling holes in subsurface formations. The bit body consists of multiple radially extending ribs, each equipped with fixed cutting elements and flow channels between adjacent ribs. The system includes flow nozzles positioned on the ribs to direct high-speed fluid (mud) toward the cutting elements for cleaning and cooling during operation. These nozzles are strategically placed in the rib’s manifold, and they communicate with a central bit body flow path to channel fluid efficiently. The design incorporates conical flow nozzles that output fluid tangentially, allowing for effective cuttings removal and cooling of the cutting elements, ensuring smoother operation and extended cutter life.

An important feature is the placement of the nozzles on the backside of the ribs, positioned to create torque in the same direction as the drill bit’s rotation. This configuration helps enhance drilling performance by aligning the fluid jets to both clean the cutters and assist in drilling force. The overall method allows for efficient fluid management, with each nozzle targeting a respective cutting element on adjacent ribs. The invention aims to improve the cooling, cleaning, and operational efficiency of rotary drill bits in challenging subsurface formations.
