Riveting screws and bolts are common parts on mechanical equipment, mainly used to link various parts.
But in the process of use, sometimes it will break.
Clean the sludge and drill holes with electric drill hand tool set; ①Remove the sludge on the surface of the broken head of the pressure riveting screw; ②.
Use the center gun to die the center gun of the section; ③, then use the electric drill to install a small diameter point, and then use a large bit suitable bit to drill the hole in the center of the cross section (note that the hole must be drilled through); ④ After the hole is drilled, remove the small drill bit, replace it with a small diameter point, and then use a larger bit suitable drill bit to continue to enlarge and drill the hole of the broken bolt.2.
Use a small and medium current to build the weld from the inside to the outside of the drill hole of the broken bolt.
Take the half of the entire length of the broken bolt at the beginning of the weld and start the weld.




28 January 2020 - The Global Oil and Gas Drill Bit Market was valued at more than USD 4.9 billion in 2014.
Increasing offshore drilling activities in the U.S. and the Middle East is anticipated to augment product demand over the forecast period.They are cutting tools used to create holes onshore and offshore as well.
Growing concern of E companies to reduce operating costs along with rising requirement for optimized drilling performance have enforced OEM manufacturers to improvise bit design and performance.
Changing customer preference for cost-effective equipment owing to of technological advancements have created opportunities for future development.
Also, sustainability of the market depends on the supply of raw materials, product development and majorly on the prices.Product Insights:On the basis of product different types of drill bits are that have been considered include fixed cutter bits and roller cone cutter.
This type of bits is significantly being employed in the present scenario as they assist in less operating time in drilling by reducing any shear and tear.Roller cone drills have largest product segment covering more than 70% of the market share globally in 2014, and is anticipated to cross over net worth of USD 1060 million by 2022.
