5 LBS Walnut Shell Media, 20/30 Mesh for Tumbling, Blasting & Crafts
- Natural 20/30 Mesh Walnut Shell Media: Made from 100% natural crushed walnut shells with a consistent 20/30 mesh (0.60–0.85 mm) particle size and Mohs hardness of 4.5–5. This 5 LB bucket provides uniform, medium-fine walnut media for tumbling, blasting, polishing, cleaning, and craft applications.
- Ideal for Tumbling & Blasting: Designed for use with rotary tumblers, vibratory tumblers, walnut blasters, and other finishing equipment. The medium-fine walnut shell particles provide gentle abrasive action for cleaning, polishing, deburring, and surface finishing without aggressive cutting.
- Great for Brass & Metal Finishing: Use as walnut tumbling media for cleaning and polishing brass casings, copper, aluminum, jewelry, metal parts, and other workpieces. Ideal for removing light oxidation, residue, carbon buildup, and surface contaminants while helping restore a clean, smooth finish.
- Natural Filler for Crafts & Pincushions: More than just polishing media, these ground walnut shells are also ideal for pincushion filling, weighted craft projects, DIY decorations, and other creative uses. The consistent particle size makes them easy to handle and distribute evenly.
- Easy to Use & Store: For vibratory tumblers, fill approximately 2/3 full; for rotary tumblers, fill approximately 1/2 full, then add your workpieces. Slight dampening can help reduce dust when needed. The resealable 5 LB bucket keeps the walnut shell media dry, organized, and ready for repeated use.
