This compact kit bundles 90 discs across three grits—coarse, medium, and fine (30 discs per grit)—designed to support fast transitions between finishes on small parts and tight spaces.

Durability you can rely on

These discs feature a nylon surface-conditioning layer for enhanced wear resistance and consistent results, paired with a premium stainless steel roll-lock holder that resists oxidation and rust for longer life in daily use.

Where they shine

The compact 2-inch discs are ideal for finishing small parts and hard-to-reach areas where larger tools struggle. They suit delicate surfaces as well as tougher materials, offering versatility across projects.

Applications you may explore

• Cleaning and coating removal
• Paint preparation, finishing, and blending

Workflow and testing tips

The set’s three grits lend themselves to material testing and process comparison. The tool-free roll-lock changes help you switch grit or disc quickly, keeping your project moving forward with fewer interruptions.

In practice, this kit supports precise, controlled finishes on small workpieces. While results depend on material and technique, you can expect smoother edges, cleaner burr removal, and refined textures as you progress through the grits.
