Type: PCB Milling Cutter Material: Carbide Cutting diameter: 0.5–3.175 mm Shank diameter: 3.175 mm (1/8'') Key benefits - Precision cutting range: available cutting diameters from 0.5 mm up to 3.175 mm let you choose the right size for fine trace isolation or larger profiling and slotting. - Durable carbide construction: hard, wear-resistant carbide maintains edge life and consistent cutting performance for longer runs and repetitive prototyping. - Easy machine compatibility: 3.175 mm (1/8'') shank fits standard 1/8'' collets on most desktop CNC routers and PCB milling machines for quick tool changes and secure holding. - Cleaner results and less rework: sharp carbide edges reduce chatter and burrs, helping produce cleaner trace edges and more reliable boards. What it does - Precision milling and isolation routing of printed circuit boards. - Profiling, slotting, and edge trimming of PCB blanks. - Suitable for rapid prototyping and small-batch board production where repeatable, accurate cuts are required. Compatibility and fit - Shank diameter: 3.175 mm (1/8'') — compatible with standard 1/8'' collet chucks and tool holders. - Intended for PCB milling machines and CNC routers that accept 1/8'' shanks. Use the cutting diameter that matches your trace width, slot size, or profile requirement. Performance notes - Carbide material delivers high rigidity and wear resistance for steady, repeatable cutting. - Available cutting diameters from micro (0.5 mm) to larger (3.175 mm) allow adaptation to fine traces, vias clearance milling, or bulk material removal. - Choose smaller diameters for detailed isolation routing and larger diameters for faster profiling and slot cutting. Typical use scenarios 1) Prototype PCB isolation routing: Use a 0.5–1.0 mm cutter to separate fine traces during rapid prototyping of single- or double-sided boards where precision matters. 2) Edge profiling and slotting: Use mid to larger diameters (1.5–3.175 mm) to trim board edges, cut mounting slots, or remove bulk material before finishing. 3) Small-batch production and rework: Swap cutters quickly in a 1/8'' collet-equipped CNC or router to maintain throughput while reducing tool-related defects. Practical tips - Match cutting diameter to the trace width and slot dimensions for best results. - Confirm your machine accepts a 3.175 mm (1/8'') shank before ordering. - Replace cutters when you notice increased drag, chattering, or poor edge quality to retain board accuracy. This carbide PCB milling cutter delivers a reliable, compatible tool option with a broad range of cutting diameters for precision routing, profiling, and small-batch PCB work.
