To Chose the Right Products
When selecting the applicable bit for optimum performance and you have to balance penetration against bit life. On occasion you can successfully sacrifice bit life for penetration, remember the rule of thumb that states that a 10% increase in penetration covers at least a 20% loss in bit life. YikYui commonly has three basic bits head designs: Flat Face, Convex and Concave. These are designed for specific applications for all rock types, hardness’s and conditions:
