Our Review
This 100-piece green rubber grinding tip set delivers solid value for general metalworking and wood finishing tasks. The rubber compound grinds smoothly on both ferrous and non-ferrous metals, with moderate cutting speed around 3,000-4,500 RPM depending on your rotary tool's power output. Tips hold up reasonably well through repeated use, though the softer rubber construction means they wear faster than ceramic alternatives—expect 20-40 hours of active grinding before noticeable degradation. The variety of shapes (cones, balls, cylinders) covers most finishing applications, making this ideal for deburring welds, polishing castings, and smoothing wood edges. Mounted arbors fit standard 3mm mandrels, though fit can be slightly loose on some tools.
What We Like
- 100 pieces provides excellent cost-per-bit value for job site inventory
- Soft rubber compound minimizes surface scoring on finished metals and wood
- Wide shape variety addresses multiple finishing tasks in one set
Watch Out For
- Rubber tips wear noticeably faster than ceramic or diamond alternatives, reducing overall longevity
- Arbor fitment inconsistencies can cause slight wobble on some rotary tools, affecting precision
The Verdict
“A practical, budget-friendly accessory set for general fabrication work, though professional shops may prefer higher-durability ceramic options for high-volume grinding.”
