Review on 8pcs Precision Engraving Bit CNC Router Tool πŸ”§ Adapter: 1/4" to 1/8" Convert for ER Collet Engraving Machine by Tim Knain

Revainrating 2 out of 5

You get what you pay for

These adapters are not exact and not accurate. I have used this with a CNC router and the run out on bits with this adapter is 100x greater than bits without an adapter. A drill with a diameter of 3 mm freely enters a hole drilled with a drill with a diameter of 2 mm. That's absurd. The adapter conforms to the product images and fits 1/8" bit to 1/4" collet. That's why I'm not giving 1 star. If you don't need precision or accuracy, but just need rough placement, they will do.

Pros
  • spring steel material, very long life, good flexibility and abrasion resistance.
Cons
  • I'll write later
