    Chip bit

     

    Taper flake bits are also called small bits. The products mainly include flat chisel bit and cross chisel bit, which are mainly used for drilling small holes and shallow holes. Cross-type drill bit is mainly used for rock drilling in tough and deep holes in cracks. Taper chip bit is mainly used in mining, quarrying, tunneling, anchoring engineering and other industries.

    Taper flake drill bit includes straight-shaped drill bit, cross-shaped drill bit and X-shaped drill bit, among which straight-shaped drill bit is also divided into horseshoe straight-shaped drill bit, regular handle straight-shaped drill bit and oblique blade straight-shaped drill bit. Taper flake bit is a kind of rock drilling tool that connects the hard alloy sheet to the brazing body through brazing process, and connects the drill bit with the drill rod through the taper of the drill bit pants during the rock drilling operation.

    Production process of taper flake drill bit: steel incoming inspection-drill bit body production (machining, warm extrusion)--trouser body heat treatment--milling alloy slot -- grinding alloy -- measuring alloy sheet -- welding alloy sheet -- grinding alloy sheet-anti-corrosion treatment -- product inspection -- packaging and warehousing.

    Common specifications and models of thread flake drill bit:

    Taper of drill bit: 4.8 degrees, 6 degrees, 7 degrees, 11 degrees, and 12 degrees.

    Alloy designation

     The selection of alloy designations should be tailored to the specific rock conditions encountered. These alloys are versatile enough to accommodate a wide range of rock grades and can be effectively utilized in drilling projects involving limestone, granite, marble, iron ore, gold mines, and other types of rock.
