Le Lematec 1/2" Air Impact Wrench | 1,000 ft-lbs, Twin Hammer, 8500 RPM, 4.85 lb
1,000 ft-lbs of Pneumatic Power. Half the Weight of Cordless.
The Le Lematec 1/2" air impact wrench delivers 1,000 ft-lbs of breakaway torque and 8,500 RPM free speed in a 4.85 lb aluminum body — roughly half the weight of an equivalent cordless wrench with battery. The twin hammer mechanism provides smooth, consistent torque delivery for lug nut removal, suspension work, brake jobs, and heavy equipment fastening without battery fade or motor overheat.
- 1,000 ft-lbs Breakaway Torque / 900 ft-lbs Working Torque — Removes the most stubborn lug nuts, rusted suspension bolts, and over-torqued fasteners. 4–10x the holding torque of typical automotive fasteners.
- Twin Hammer Mechanism — Balanced, rapid impact delivery for consistent operation and smooth torque output. Built to last 10+ years with proper maintenance.
- 8,500 RPM Free Speed — Fast bolt removal without sacrificing control. Variable speed trigger adjusts impact intensity for both removal (full power) and installation (controlled torque).
- 4.85 lb Lightweight Aluminum Body — Significantly lighter than cordless equivalents (6–8 lbs with battery). Reduces fatigue during extended professional use.
- 7.28" Compact Length — Fits into tight engine bays and confined spaces where larger wrenches can't reach.
- 17 CFM @ 90 PSI — Operates efficiently on a 20-gallon compressor (5+ CFM) for intermittent use; 30-gallon with 7+ CFM recommended for continuous heavy-duty work.
- 1/4" NPT Air Inlet — Standard fitting compatible with most shop air hose setups.
Why Pneumatic Over Cordless?
Pneumatic impact wrenches deliver constant torque without battery fade. At 4.85 lbs, this wrench is roughly half the weight of an equivalent cordless model — reducing fatigue during extended use. No batteries to charge, no motors to overheat, and the twin hammer mechanism is built for daily shop use.
Air Supply Requirements
Operates at 90 PSI. A 20-gallon compressor with 5+ CFM handles most intermittent applications (removing a set of lug nuts). For continuous heavy-duty use, a 30-gallon compressor with 7+ CFM is recommended.
Compatible With
- Sockets: All 1/2" drive impact sockets — SAE and metric. Always use impact-rated (black oxide) sockets — never chrome sockets, which can shatter under impact forces.
- Accessories: 1/2" drive impact extensions, universal joints, torque sticks, adapters
- Compressors: 7+ CFM at 90 PSI, 20–30+ gallon tank

Frequently Asked Questions
What size compressor do I need?
A 20-gallon compressor with 5+ CFM at 90 PSI handles intermittent use. For sustained heavy-duty work, use a 30-gallon compressor with 7+ CFM. General rule: your compressor should deliver 1.5x the tool's CFM requirement.
Do I need impact sockets?
Yes — always use impact-rated (black oxide) sockets. Chrome sockets are hardened differently and can shatter under impact forces, creating a dangerous projectile. Impact sockets are designed to flex slightly under shock loads rather than crack.
How does 1,000 ft-lbs compare to other wrenches?
Most passenger car lug nuts are torqued to 80–100 ft-lbs; truck lug nuts run 140–250 ft-lbs. At 1,000 ft-lbs breakaway, this wrench provides 4–10x the holding torque of typical fasteners — enough to overcome rust, thread-locking compounds, and over-tightened bolts on virtually any vehicle.
