How is the carbide button installed into the Tapered Button Bit？
The Tapered Button Bit can be fixed using one of three general techniques: welding, cold fixing, or hot insertion. The supply of Tapered Button Bit is produced using a welding method, which was first used to fasten teeth. It uses a fairly easy way. In order to weld the alloy carbide button on the bit body, either by brazing or silver welding, it is primarily necessary to determine the size of the hole and the alloy cylindrical tooth through the welding gap, drill the appropriate hole on the bit body in accordance with the bit's structural form. The specifications for cylindrical tooth size and drilling precision are not stringent. Its drawbacks include being relatively challenging to use, leaving visible welding scars easily, and being relatively difficult to operate.
Small diameter Tapered Button Bit, which was once common, have been phased out and are now mostly used to create tapered hole connections. Currently, the majority of businesses use the cold-fixing method. Calculating the fit clearance between the hole and the tungsten carbide according to the yield of the steel used to make the Tapered Button Bit body is the process' key step. By applying force from outside, the interference fit method presses the carbide button into the hole. Its strengths include an easy learning curve and a high level of production efficiency, but a dearth of stability.
