Efficient integrated operation: The high-performance drilling and tapping combination set achieves breakthrough in simultaneous drilling and tapping, which is 50% more efficient than traditional step-by-step operation. Whether it is a small project of home improvement or industrial-grade mass production, it can quickly advance the project progress and save a lot of time and labor costs. ​ Precise adaptation of multiple sizes: The set includes 4 saws of different specifications (the specific size is not clear, and can be selected according to actual needs), covering the operation scenes from fine hole processing to large apertures. Whether it is small parts assembly or large component production, it can match the appropriate drill bit and easily cope with various complex tasks. ​ Innovative four-blade eccentric design: It adopts a unique four-blade serrated eccentric drill bit structure to optimize the cutting path, reduce material debris residue, and drill and tap in one step. The surface finish reaches Ra3.2, and no secondary grinding is required, which simplifies the process and improves the overall operation quality.​ Titanium film coating is long-lasting and durable: The surface of the drill bit is covered with advanced titanium film coating, and the high temperature resistance is increased to 800℃, and the wear resistance is increased by 3 times. Even if it works continuously for more than 20 hours, it can still maintain a sharp cutting state, ensuring long-term stable and efficient work and extending the service life. ​ Universal adaptability to all materials: It is suitable for a variety of materials such as metal, wood, and plastic. Whether it is aluminum alloy door and window processing, solid wood furniture production, or plastic model modification, it can exert stable performance and show excellent versatility, providing reliable support for operations in different fields. ​
