3.175mm Carbide PCB Engraving Bit – 30 Degree 0.2mm V-Shape CNC Router Tool in Pakistan

Overview 

Precision matters when you are isolating fine traces on a circuit board or engraving micro-text. Our 30-Degree 0.2mm Carbide V-Bit is manufactured from ultra-fine-grained tungsten carbide steel, providing exceptional hardness, wear resistance, and cutting edge sharpness. Featuring a standard 3.175 mm (1/8″) shank, it fits perfectly into popular desktop CNC routers (like the CNC 3018 Pro) and standard rotary tool collets.

Key Features

• Ultra-Sharp 0.2mm Tip: Engineered for precise isolation routing on copper-clad PCBs without tearing the traces.

• Premium Tungsten Carbide: Offers superior rigidity and longer tool life compared to standard HSS bits when cutting abrasive materials.

• Efficient Chip Removal: Large V-groove flute design easily clears debris out of the path, preventing melting on plastics or acrylics.

• Wide Material Compatibility: Excellent for copper plates, aluminum, FR4 PCB blanks, acrylic, PVC, wood, and MDF.

Technical Specifications 

Recommended Machining Parameters 

• Spindle Speed: 10,000 – 20,000 RPM (Higher speeds reduce the risk of tip breakage)

• Feed Rate: Start conservative (100 mm/min – 300 mm/min) to protect the micro-tip on hard substrates.

• Plunge Rate: Keep plunge rates very low (30 mm/min – 50 mm/min ) to avoid breaking the 0.2mm tip upon entry.
