Top 5 Best Sandblasters for Metal
1. Eastwood Benchtop Sandblaster
The Eastwood Benchtop Sandblaster is designed for smaller parts and projects. It’s a fully enclosed unit, keeping the mess contained, which I really appreciate. You can use it for cleaning, etching, or finishing metal.
Pros:
- ✅ Enclosed design minimizes mess.
- ✅ Built-in light helps with visibility.
- ✅ Compact size fits well in smaller workshops.
Cons:
- ❌ Limited to smaller parts due to cabinet size.
- ❌ Some assembly required.
- ❌ Air compressor not included.
Verdict: Great for hobbyists or small shops working with smaller metal pieces. If you need to blast larger items, this might not be the best choice.
2. TCP Global 10 Lbs Capacity Portable Sandblaster
This portable sandblaster from TCP Global is a great option when you need to take the work to the metal. Its portability makes it easy to maneuver around larger objects or work outdoors.
Pros:

Verdict: Perfect for tackling rust and paint on larger items that can’t easily fit in a cabinet blaster. Keep in mind the need for proper safety gear due to its open nature.
3. Mastercraft Portable Sandblast Kit
The Mastercraft Portable Sandblast Kit is your go-to for smaller, more delicate sandblasting tasks. It’s a siphon feed blaster, meaning it draws the abrasive material from an external container. This allows for more extended use without needing to stop and refill frequently, which I found super handy.
Pros:
- ✅ Lightweight and easy to handle.
- ✅ Siphon feed design allows for continuous blasting.
- ✅ Suitable for detailed work and small areas.
Cons:
- ❌ Requires an air compressor (not included).
- ❌ Siphon feed can be less consistent than pressure feed.
- ❌ Small capacity may require frequent refills for larger jobs.
Verdict: Ideal for hobbyists and DIYers tackling small-scale projects. If you’re working on intricate metal designs or need to remove rust from tight spaces, this kit offers precision and control.
4. ABN Portable Gravity Feed Abrasive Blaster
The ABN Portable Gravity Feed Abrasive Blaster is designed for spot repairs and small projects where precision is key. The gravity feed design helps ensure a consistent flow of abrasive, which I found to be quite useful for detailed work.
Pros:
- ✅ Gravity feed ensures consistent abrasive flow.
- ✅ Compact and easy to handle.
- ✅ Adjustable air pressure for different materials.
Cons:
- ❌ Small capacity requires frequent refills.
- ❌ Can be tiring for prolonged use.

Buying Guide
Choosing the right sandblaster for metal depends on your specific needs and the types of projects you’ll be tackling. Here are a few things to consider:
- Project Size: For small parts, a benchtop blaster is ideal. For larger items, a portable unit is more practical.
- Abrasive Type: Different abrasives work best for different metals and finishes. Aluminum oxide is good for general use, while glass beads are gentler for delicate surfaces.
- Air Compressor Requirements: Make sure your air compressor can supply enough CFM (cubic feet per minute) at the required PSI (pounds per square inch) for the sandblaster.
- Portability: If you need to move the blaster around, choose a portable model.
- Dust Collection: Enclosed blasters with dust collection systems are cleaner and safer to use.
- Safety Gear: Always wear a respirator, gloves, and eye protection when sandblasting.
Consider the material you’re blasting. Some abrasives are too harsh for softer metals.
Maintenance is key. Regularly clean your sandblaster to prevent clogs and ensure optimal performance.
FAQs
Q: What kind of abrasive should I use for sandblasting metal?
A: Aluminum oxide is a good all-around abrasive for removing rust and paint. Glass beads are gentler and suitable for polishing or cleaning delicate metal surfaces. Silicon carbide is very aggressive and used for heavy-duty stripping.
Q: Do I need a special air compressor for sandblasting?
A: Yes, you need an air compressor that can deliver enough CFM (cubic feet per minute) at the required PSI (pounds per square inch) for your sandblaster. Check the sandblaster’s specifications to determine the correct compressor size.
Q: How do I prevent rust after sandblasting metal?
A: After sandblasting, immediately apply a primer or coating to protect the bare metal from moisture and prevent rust. You can also use a rust inhibitor.
Q: Is sandblasting safe?
A: Sandblasting can be dangerous if proper safety precautions aren’t taken. Always wear a respirator, gloves, and eye protection to avoid inhaling dust and getting abrasive materials in your eyes or on your skin.
Q: Can I use regular sand in a sandblaster?
A: No, you should not use regular sand in a sandblaster. Regular sand contains silica, which can cause silicosis, a serious lung disease. Use approved abrasives like aluminum oxide, glass beads, or silicon carbide.
Conclusion
Finding the best sandblaster for metal doesn’t have to be difficult. Consider the size of your projects, the type of metal you’re working with, and your budget. Whether you opt for a benchtop model for small parts or a portable blaster for larger jobs, the right tool will make your metalworking projects much easier and more efficient. Remember to prioritize safety and choose the appropriate abrasive for the best results.
