#100 Aluminum Oxide 8 LBS Medium Sand Blasting Abrasive - Durable

In this review the reviewer tested the #100 Aluminum Oxide 8 lb bag to judge whether it is a practical media for cabinet and gun blasting. The bottom line: this abrasive is for users who need a hard, longlasting grit that cuts faster and holds shape far longer than common glass or silica media. It is especially useful when etching glass or blasting metals where a sharp, aggressive cut and material cleanliness matter, and the review found it to be efficient for repeated cycles in small cabinets and blasting guns.

Key Features

• Hardness: Being the second hardest mineral after diamond, this abrasive provides aggressive cutting that shortens blasting time on stubborn coatings and rust.
• Longevity: The sharp angular grit stays effective through many cycles, which reduces replacement frequency compared with softer media.
• Non-reactive: The media does not interfere with coatings or surface prep, keeping substrates clean and ready for finishing.
• Versatile use: Suitable for wet and dry blasting, it handles cleaning, deburring, etching and finishing across a range of substrates including glass and metal.
• High density: A higher specific gravity and bulk density help the abrasive deliver consistent momentum for efficient material removal.

Who It's For

This product is aimed at hobbyists and small shop operators who run blast cabinets or handheld blasting guns and need a reliable, reusable abrasive. It is particularly well suited for people who etch glass, texture gun parts, or remove coatings from metal where a harder grit is required.

It may be less appropriate for users who want a very fine, delicate finish or who need an ultra-low cost disposable media; those buyers might prefer a softer glass bead or lower cost alternative though they will trade longevity and aggressiveness.

Pros & Cons

Pros

• Long lasting sharp grit reduces media replacement and maintains cutting performance over many uses.
• Highly efficient at cutting and etching due to high hardness and angular particle shape.
• Non-reactive and clean, so it will not contaminate parts before coating or finishing.

Cons

• Higher upfront cost per bag than some softer disposable media, though longevity offsets this for frequent users.
