Core bit

Carbide Core Tips is a tool, usually used by mining /milling machinery to cut coal, rock, and other hard materials. The raw material of the carbide coring tips (picks) is generally: pick carbide head and tail tungsten-cobalt alloy, which is synthesized from carbon tungsten and cobalt. Tungsten carbide is the hardest metal material, and at the same time it is very brittle; after being synthesized with soft cobalt, it forms an alloy with high hardness and wear resistance, which can withstand super shock loads. The general structure of the pick is that a carbide tip is inlaid on the quenched and tempered low-alloy structural steel cutter body. The picks are subjected to high periodic compressive stress, shear stress, and impact stress during operation. The simple drawing of the carbide core tips is as below. Different grades, sizes, and shapes can be produced by your requirement. Classification of Carbide Core Tips: The picks ( Carbide Core Tips) generally include: headwall for roadheaders, pick picks for shearers, knife picks, rotary teeth for rotary drilling rigs, milling teeth for milling machines, and bucket teeth for excavators. Heading feet for roadheaders are mainly used for coal roadway or semi-coal rock roadway and roadway driving of soft rock, and can also be used for tunnel construction such as railways, highways, and hydraulic engineering. At present, roadheaders mainly use pick-shaped picks. Picks are generally brazed from alloy steel tooth bodies and carbide tips.
