Precision Tungsten Steel CNC Engraving Bit

Ultra-durable 3.175mm shank tungsten steel construction withstands high-speed rotations and prolonged use without dulling. Flat-bottomed V-tip design delivers razor-sharp engraving for PCB circuit boards, acrylic, and woodworking projects. Mirror-polished cutting edges minimize friction for burr-free finishes.

Ideal for CNC routers, DIY engraving machines, and precision PCB prototyping. Hardened steel body resists heat deformation during extended milling sessions. Compatible with most 1/8" collet systems for universal workshop integration.

Micro-grooved flute design efficiently clears debris during high-precision carving. Electroplated anti-rust coating ensures long-term storage stability. Batch pricing available for industrial-scale manufacturing needs.
