This kit consists of 16 clamps and one specialized pliers for effortlessly opening the clamp tips,designed for picture frames,trim,crown molding,baseboards,door and window casings,and various compound miter joint fixing applications.It is an ideal tool for professional carpenters,contractors,and woodworking enthusiasts. Core advantages that make Feiyang clamps outperform competitors:the tip-sharpening process is highly sophisticated,using custom-built precision CNC equipment and tungsten steel molds specifically designed for clamp tip grinding to achieve extremely sharp tips with a small taper—it's no easy task to grind large quantities of high-hardness spring steel while maintaining such precision.Feiyang ensures every single clamp meets this sharpness standard,so even when clamping challenging miter angles (such as 135 degrees on an octagon),it instantly bites into the wood joint with a secure hold,no slipping,and prevents the tips from scratching the wood. Since its launch on Amazon in 2018, the Feiyang miter clamp set outstanding performance has earned recognition from numerous professional carpenters,embodying the true standard of professional tools. Only through hands-on experience can you appreciate the fundamental difference from competitors.
