Packaging
- Inner box: 30.7 × 12.4 × 11 cm
- Master carton: 53 × 32.4 × 35.5 cm
- Packing: 12 pcs / N.W. 15.5 / G.W. 16.6 / 2.2'
Why Professionals Choose This Tool
- Heavy-Duty Grinding: Wider 3/4" belt and longer 20-1/2" loop provide more aggressive material removal and longer belt life than compact models
- Industrial Metal Finishing: Designed for professional welding shops, fabrication facilities, and production environments
- Extended Belt Life: Larger belt surface area distributes heat and wear — belts last 2-3x longer than 1/2" x 13" belts on the same job
- Weld Seam Blending: Wide belt smooths MIG, TIG, and stick weld beads flat for inspection-ready finishes
- Robust Construction: Built for daily production use with heavy-duty bearings and reinforced housing

Frequently Asked Questions
What air compressor do I need for the LE-BS-708B Air Belt Sander 3/4" x 20-1/2"?
This tool requires approximately 4-6 CFM at 90 PSI. A compressor with at least a 20-gallon tank provides sufficient air volume for intermittent use. For continuous operation, a 30+ gallon tank is recommended.
Is the LE-BS-708B Air Belt Sander 3/4" x 20-1/2" compatible with my existing air setup?
Yes. Like all Le Lematec tools, it uses a standard 1/4" NPT air inlet fitting that's compatible with most compressors, hoses, and quick-connect couplers from any manufacturer.
When should I choose the 3/4" belt sander over the 1/2" model?
Choose the LE-BS-708B (3/4" x 20-1/2") when you need faster material removal, longer belt life, or are working on larger flat surfaces. The wider belt covers more area per pass and handles heavier grinding jobs. Choose the LE-BS-706B (1/2" x 13") for tight spaces, detail work, and contour sanding where a narrow profile is essential.
What CFM does my compressor need for the LE-BS-708B?
The LE-BS-708B requires 5-6 CFM at 90 PSI for optimal performance. A 30-gallon or larger compressor with at least 6 CFM output provides enough air for continuous sanding without pressure drops. For intermittent use, a 20-gallon compressor works but expect short recovery pauses.
Can I use this belt sander on stainless steel?
Yes. Use zirconia or ceramic belts (60-120 grit) for stainless steel — they cut cooler and last longer than aluminum oxide on stainless. Keep the sander moving to prevent heat buildup and discoloration. The LE-BS-708B handles stainless weld blending, surface finishing, and scratch removal.
How It Compares
The LE-BS-708B's wider 3/4" belt and 20-1/2" length cover more surface area per pass than the narrower LE-BS-706B, making it better for larger panel work and heavy-duty grinding. Compared to disc sanders, belt sanders provide better control on flat and contoured surfaces without creating swirl marks. The 708B is ideal for production environments where speed and coverage matter more than tight-space access.
