10 piece carbide cnc router bit set with diameters from 0.8 to 3.175 mm. These bits are made from ultra-fine carbide for high hardness, high strength, high wear resistance, and strong bending strength, enabling high speed cutting. This is a cost-effective, convenient tool set that delivers solid milling and cutting performance to improve work efficiency and overall output. Each bit has a sharp cutting edge, producing clean, neat milling results and smooth edges on holes and plates. The surface quality is clean with no glitches, contributing to a safer workflow for operators and machines. Widely applicable for material processing across PCB, SMT, CNC, mold making, plastic fiber, carbon fiber, hard wood, acrylic, and printed circuit boards, among others. Use scenarios - Electronics manufacturing: PCB and SMT milling and drilling for precise, reliable results. - Prototyping and fabrication: shaping hard wood, acrylic, carbon fiber, and plastic fiber parts with clean edges. - Mold making and finishing: refining surfaces and features in molds and related components.
