Aanraku Twofers Grinder Bit
Stacked grinding surfaces extend useful life before replacement.

The 220-grit Twofers pair is for the last pass, not aggressive reshaping. It removes less glass per touch and leaves a calmer edge, which is useful around thin pieces, narrow points and glass that chips easily.
Reasons to choose it
- Two usable grinding bands
- Double-layer surface
- Diamond abrasive
Consider before buying
- Confirm diameter and shaft
- Position the sponge correctly
- Choose a standard 100-grit head when speed and substantial edge correction matter more than a fine finish.

What stood out during our research
The manufacturer page had no owner reviews when checked, so the recommendation rests on published size, grit and double-plated construction.
What ownership is actually like
Keep the full abrasive band wet and use light pressure. Fine grit can feel slow if you ask it to correct a badly oversized piece; rough-shape first with a standard bit, then switch for the finishing pass.
Who it suits
This is a strong shortlist candidate for two usable grinding bands. The useful question is whether that describes most of your work, not merely one future project.
When another tool makes more sense
Choose a standard 100-grit head when speed and substantial edge correction matter more than a fine finish.
