Buying Guide
What matters most when choosing 2-inch Roloc discs:
- Disc material: Aluminum oxide provides a good balance of wear and affordability on wood and metal; zirconia offers faster stock removal on hard metals and painted surfaces but can wear quickly in softer materials.
- Grit range: Coarse grits (40–60) remove material quickly; medium (80–120) smooth; fine (180–240) finish. Pick sets with a logical progression for your typical workflow.
- Attachment system: Quick-change R-Type or similar systems save time and reduce tool downtime. Ensure compatibility with your 1/4″ shank holder and tool arbor.
- Disc backing and durability: Look for sturdy backing with robust grains to resist loading and spalling, especially for metal prep and paint removal.
- Pack size and variety: Larger kits reduce restock needs, but avoid oversized sets if you rarely use some grits. Consider balancing core grits you actually use.
