Chip bit

Taper flake bits are also called small bits. The products mainly include one-word horseshoe drill bit and one-word oblique-blade drill 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 in-line drill bit, cross drill bit and X-type drill bit, among which the in-line drill bit is divided into horseshoe in-line, constant shank in-line drill bit and oblique blade in-line 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 threaded connection drill bit: steel incoming inspection-brazing body production (machining, warm extrusion)-trouser body heat treatment-milling alloy groove-grinding alloy-measuring alloy sheet-welding alloy sheet-grinding alloy sheet-anti-corrosion treatment-product inspection-packaging and warehousing
