| #7 Glass Beads – 10 lb | HDURCIR | 60-80 Mesh | 10 lb | Coarser finish; good for rapid material removal |
| #12 Glass Beads – 10 LBS | Industrial Mineral Supply | 140-230 Mesh | 10 LBS | Extra fine; ideal for precision cleaning and peening |
| #10 Glass Beads – 10 LBS | Industrial Mineral Supply | 100-170 Mesh | 10 LBS | Fine to medium blend for finishing and sealing pores |
#10 Glass Beads – 10 lb (HDURCIR) — Medium Finish
HDURCIR presents #10 Glass Beads in a 10 lb package, designed for blast cabinets or sand blasting guns. The 100-170 mesh range is well suited for metal cleaning, surface prepping, and achieving a balanced finish that preserves tolerances while removing contaminants. This media is commonly used to clean parts without introducing ferrous pollutants, and it can help seal pores and refine surface texture through glass bead peening.
#7 Glass Beads – 10 lb (HDURCIR) — Medium Coarse
This #7 glass bead grade provides a coarser finish, suitable for faster material removal and surface prep where speed is a priority. The listed weight is 12 lb in the packaging notes, and customers may find larger packs more cost-effective. Use in blast cabinets or sand blasting guns to achieve a pronounced, uniform finish while maintaining surface integrity.
#12 Glass Beads – 10 LBS — Extra Fine
Industrial Mineral Supply offers #12 glass beads in a 10 lb package with an extra-fine 140-230 mesh range. This media is ideal for precision cleaning of metal parts, removing residues without altering tolerances, and producing a smooth, peened finish that blends machine marks and seals pores.
#10 Glass Beads – 10 LBS — Fine
Industrial Mineral Supply’s #10 glass beads in a 10 lb bag are described as round beads within the 100-170 mesh range. They are suitable for cleaning and preps of metal surfaces without tolerances shifts or ferrous contamination, and they offer the finishing benefits associated with glass bead peening for a balanced surface texture.
HDURCIR Glass Beads — Additional Medium Option
Using the same HDURCIR offering in a different section highlights consistency in medium-grade glass bead media for 100-170 mesh finishes. This additional listing reinforces access to a reliable medium finish for a variety of blast cabinet setups and gun applications, ensuring a uniform, clean surface and minimized tolerance impact.
Buying Guide: Key Purchase Considerations
When selecting glass bead blasting media, consider the following factors to optimize results and cost efficiency:
- Mesh size and finish: Coarser meshes (60-80) remove material faster; finer meshes (140-230) yield smoother finishes and better surface refinement. Match mesh to your part geometry and coating requirements.
- Media weight and packaging: Larger bags (e.g., 10 lb or more) may reduce cost per pound. Consider annual usage to determine optimal bundle size.
- Prepping vs. finishing: For thorough cleaning and surface prep without changing tolerances, glass beads at 100-170 mesh are a common compromise between cleaning power and texture.
- Ferrous pollutant risk: Glass beads generally minimize ferrous contamination, making them suitable for applications that require clean surfaces prior to coatings or welding.
- Bead peening benefits: The peening action of glass beads can seal pores and blend minor machine marks, contributing to a uniform finish that supports coating adhesion.
- Equipment compatibility: Ensure your blast cabinet or blasting gun can handle the selected bead size and that your nozzle and media recovery system support the media’s hardness and flow characteristics.
- Cleaning and maintenance: After blasting, rinse or wipe parts to remove residual dust and inspect for surface uniformity. Store media in a dry, sealed container to prevent moisture absorption.
- Environmental and safety: Use appropriate PPE, ensure proper ventilation, and follow supplier guidelines for disposal or recycling of spent media if applicable.
