Product Overview

Engineered for extreme heavy-duty applications, this Large-Frame 1/2″ Brushless Impact Wrench delivers industrial-grade fastening power in a cordless platform. Driven by a 600W high-efficiency brushless motor, it outputs 1500N.m fastening torque and a massive 1650N.m max breakaway torque. The robust 2-speed transmission (1400/1800 RPM & 2400/2500 BPM) provides precise power modulation for M12~M24 standard and M10~M18 high-strength bolts. Featuring a hardened 1/2″ (12.7mm) square drive and 14-36mm socket compatibility, it seamlessly replaces pneumatic tools in steel structure assembly, heavy machinery maintenance, mining, and fleet service. Ideal for global distributors and B2B buyers seeking reliable OEM/ODM cordless fastening solutions.

Key Features

1650N.m Breakaway Power: Instantly fractures seized, rusted, or over-torqued nuts on heavy equipment, trucks, and structural steel.
2-Speed Heavy-Duty Transmission: Low gear (1400 RPM/2400 BPM) for controlled high-torque fastening; High gear (1800 RPM/2500 BPM) for rapid nut breaking.
600W Brushless Motor: 35% longer runtime, zero carbon maintenance, optimized thermal management & extended service life under continuous load.
Large-Frame Durability: Reinforced housing & impact-resistant components built to withstand harsh job-site environments & high recoil forces.
1/2″ Hardened Anvil: Heat-treated alloy steel drive with 14-36mm socket range, perfectly matched for M12-M24 & M10-M18 bolt grades.
Job-Site Ready: Anti-vibration overmold grip, one-touch forward/reverse, high-lumen LED work light & battery fuel gauge.

FAQ

Q1: What is the MOQ for wholesale or OEM orders?
A: Neutral packaging starts at 50 pcs. Custom OEM/ODM orders require 200 pcs. Evaluation samples are available.

Q2: Is this sold as a bare tool or complete kit?
A: Both options available. Kits include 2× high-capacity Li-ion batteries, fast charger, 14-36mm heavy-duty socket set, extension bar & reinforced BMC case.

Q3: How should the 2-speed settings be applied on site?
A: Gear 1 (1400 RPM/2400 BPM) delivers controlled torque for M10-M18 high-strength bolts to prevent thread stripping. Gear 2 (1800 RPM/2500 BPM) maximizes impact energy for breaking M20-M24 standard bolts and rusted heavy machinery fasteners.

Q4: How do you guarantee torque consistency for bulk shipments?
A: Every unit undergoes digital torque calibration, 30-min continuous impact aging, and anvil stress testing. Full QC reports & video inspections provided.

Q5: What are your payment & shipping terms?
A: T/T (30% deposit, 70% before shipment), L/C, or Alibaba Trade Assurance. Shipped via sea, air, or express worldwide with DDP options.
