Frequently Asked Questions
What air compressor do I need for the LE-G748 3" Composite Air Cut-Off Tool?
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-G748 3" Composite Air Cut-Off Tool 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.
Why is the cutting disc not included?
Cut-off wheels are consumable items — professionals prefer to choose their own brand, material type, and thickness. Standard 3" x 1/16" wheels with a 3/8" arbor hole are available at every auto parts store and industrial supplier. Aluminum oxide wheels are best for general steel cutting; zirconia wheels last longer on stainless steel.
Is this tool safe for cutting near fuel lines?
Yes. Unlike electric cut-off tools and reciprocating saws, the air-powered LE-G748 produces zero electrical sparks from the motor. However, the cutting disc itself will produce friction sparks on metal. Always have a fire extinguisher nearby and never cut into fuel-containing components. The zero-electrical-spark motor makes it safer than electric alternatives for automotive undercar work.
How long do 3" cut-off wheels last?
A standard 3" aluminum oxide wheel cuts through approximately 20-30 automotive exhaust clamps or 10-15 linear inches of exhaust pipe before needing replacement. Zirconia wheels last about 50% longer. Wheel life depends on material hardness, feed pressure, and whether you allow the tool to reach full speed before cutting.
What disc size does this cut-off tool use?
This tool uses standard 3-inch (76mm) cut-off discs with a 3/8-inch arbor. These discs are widely available at hardware stores and online. Keep spare discs on hand for extended cutting sessions.
What CFM does this air cut-off tool require?
This tool requires approximately 4-6 CFM at 90 PSI for optimal performance. A compressor with at least a 20-gallon tank is recommended for continuous cutting work to maintain consistent air pressure.
Can I use this for cutting sheet metal and exhaust pipes?
Yes, this air cut-off tool excels at cutting sheet metal, exhaust pipes, bolts, brackets, and thin-wall tubing. The 3-inch disc provides clean, precise cuts with minimal sparks compared to angle grinders.
