Fine Cut Light Green 1/4" Plastic Pyramids 1 Lb Pack

Fine Cut (Light Green) 1/4" Plastic Pyramids are plastic-bonded abrasive media for wet tumbling / vibratory finishing. Use with a small amount of water and an appropriate detergent compound to refine surfaces on soft and medium-hard metals. This fine cut is typically the third step after coarse and medium media. Sold by the pound.

Key Features

• Fine-cut plastic pyramids for very smooth surface conditioning
• Excellent on softer metals (aluminum, brass, zinc, copper alloys)
• Pyramid shape reaches edges and interior features effectively
• Prepares parts for burnishing with steel shot or dry final polish
• Formerly white—dye lots vary; cutting action remains the same

Specifications

Recommended Process Pathway

1. Coarse cut – establish uniform surface and remove burrs: Coarse Cut Brown 1/4" Plastic Pyramids.
2. Medium cut – refine surface: Medium Cut Dark Green 1/4" Plastic Pyramids.
3. Fine cut (this media) – smooth to pre-polish.
4. Optional burnish – brighten with Stainless Steel Mixed Shot – 1 lb, or proceed directly to a dry final polish.

Use & Notes

• Maintain a light slurry with water; add detergent compound as needed.
• Check parts periodically—cycle time depends on alloy, mass, and machine.
• Plastic media is ~30% lighter than ceramic, does not peen burrs, and will not discolor metals; commonly used prior to anodizing, plating, or painting.
