1、Splicing is more convenient and beautiful. Three holes can be drilled on the inner side of the board. After splicing, there is onlyone screwhead left on one side of the board, and there are no screw holes on the other side of the board. The three connectors are HiddenInside for easy disassembly and installation. 2、The applicable plate thickness can range from 15mm to 30.5mm, which can meet your various thickness drilling needs to the maximum extent. 3、By using the extension rod and the positioning rod, it is possible to accurately drill holes at the corresponding positions of two plates. 4、By using a puncher and a round wooden tenon, two boards can be easily joined in the same direction. 5、In addition to achieving three holes connection, it is also possible to performs two in one punching, and the punched boards are also very convenient for splicing. 6、Made of fine quality aluminum alloy, with clear and comfortable textures. 7、Smooth curved lines, smooth without burrs, comfortable grip. The 3 In 1 positioning puncher can conveniently and quickly connect the plates, while maintaining a beautiful appearance. It is practical and widely used in woodworking plate connection applications.
