1/8" 60° 2-Flute Spiral V-Engraver Carbide CNC Bit for PCB Isolation & Fine Engraving Made in USA. E107

60° 2-flute spiral carbide V-engraver designed for precision engraving, PCB trace isolation, and high-quality edge finishing.

Unlike standard straight V-bits, this tool features a true 2-flute spiral cutting geometry, providing smoother cutting action, improved chip evacuation, and significantly reduced chatter. This results in cleaner edges, better surface finish, and more consistent performance across a wide range of materials.

Why choose a spiral V-engraver?
The spiral flute design actively removes chips from the cutting zone, reducing heat buildup and improving cut quality. Compared to straight V-bits, this allows higher feed rates, better tool life, and cleaner engraving results—especially in plastics, PCB materials, and non-ferrous metals.

Why a 60° angle?
A 60° tip angle provides a strong balance between detail and durability. It is ideal for general engraving, PCB isolation routing, and applications where both strength and precision are required.

Typical Applications

• PCB circuit isolation (trace definition)
