Which two parts does carbide drill consist of?

Carbide bits include blank bits and carbide parts. Its structure is the arrangement of cemented carbide on the blank bit, the number of inlays, the edge (the alloy part below the bottom lip of the blank bit), etc., according to the nature of the drilling rock. Whether it is reasonable or not directly affects the drilling speed, the service life of the bit and the determination of technical parameters, but also affects the consumption of raw materials.

Carbide bits are divided into four base types: solid carbide bits, carbide indexable blade bits, welded carbide bits and interchangeable carbide crown bits. Each bit has benefits that suit the specific machining premise.

A type of drill used in core drilling. The steel cylindrical bit body is named for the cemented carbide cutting tool welded with tungsten carbide. The shape of the cemented carbide cutting tool and the number of inserts and welds on the drill, the arrangement and the different angles of inserts and welds are called the bottom edge, the inside edge and the outside edge to ensure that there is a gap between water and powder. The upper part of the bit body is connected with the core pipe with a wire buckle. A water trough is opened on the side of the bit body and a water opening is also opened on the bottom lip. Water tank and water outlet are to ensure the flow of washing liquid, to remove rock powder and cool the drill bit. In order to increase the clearance when drilling into clay and shale formations, the ribs are welded on the inner and outer walls of the hard alloy bit, which is called the rib drill. Needle carbide self-grinding drill bits can be used in highly abrasive hard formations. General hard alloy drill bit drilling rock drillability for class II to VII stratum; Needle carbide drill bit can drill into class VI - Ⅷ rock.
