Heavy Duty Brushless Cordless Impact Wrench

Product Overview

From lightweight maintenance to extreme industrial bolt tightening, our Brushless Cordless Impact Wrench Series offers an all-encompassing power tool solution. Featuring high-efficiency brushless motor technology, this platform delivers superior energy transfer, extended runtime, and maintenance-free operation. The series spans across 1/2" (12.7mm), 3/4" (19mm), and 1" (25.4mm) square drive sizes, providing an astounding torque spectrum—from compact 140N⋅m models up to the massive flagship PB3000 boasting 3000N⋅m fastening torque and 4000N⋅m breakaway loosening torque. Equipped with 18V/21V Lithium-Ion fast-charging battery systems, intelligent electronic speed switches, and anti-vibration ergonomic grips, this lineup is built for automotive technicians, heavy equipment mechanics, and steel construction crews.

Key Features

Advanced Brushless Motor Technology:Eliminates carbon brush wear and internal friction, delivering up to 50% longer lifespan, less heat generation, and greater working efficiency.

Extreme Torque Spectrum up to 4000 N·m:Wide performance matrix from compact 140N⋅m models up to heavy industrial 4000N⋅m breakaway torque, easily busting rusty or over-torqued bolts.

Versatile Square Drives:Accommodates standard sockets from 8mm to 60mm across 12.7mm (1/2"), 19mm (3/4"), and 25.4mm (1") drives.

Precision Electronic Speed & Impact Control:Multi-speed/impact adjustment triggers allow precision torque application on standard (M5-M42) and high-strength bolts (M5-M30).

Ergonomic Anti-Vibration & LED Design:Soft rubber-overmolded handle absorbs impact vibrations, while integrated LED work lights (on select models like PB600) illuminate dark work areas.

Applications

Light & Commercial Automotive Service: Passenger car tire removal, brake service, chassis, and engine bay maintenance (1/2" models).

Heavy Truck & Bus Maintenance: Heavy wheel lug nuts, suspension bolts, and diesel engine servicing (3/4" models).

Steel Construction & Infrastructure: High-torque structural bolt fastening on I-beams, cranes, and towers (3/4" & 1" heavy models).

Mining, Oil & Gas, Agriculture: Field maintenance on excavators, heavy tractors, and industrial pipelines.

FAQ

Q1: Which model is suitable for heavy truck lug nuts and large machinery maintenance?

A: For heavy trucks, agricultural equipment, and large machinery, models like the PB1500, PB2000, PB2300 (3/4" drive) or PB3000 (1" drive, up to 4000N·m breakaway torque) are recommended for handling large M24-M42 bolts.

Q2: What is the difference between 1/2", 3/4", and 1" square drives?

A: 12.7mm (1/2") is the standard size for automotive repair and general construction; 19mm (3/4") and 25.4mm (1") are designed for heavy commercial trucks, industrial plants, and massive structural steel bolting requiring high torque transfer.

Q3: Are the batteries interchangeable across different models in this series?

A: Yes, most 21V models share a compatible Lithium-Ion slide battery platform, enabling seamless fleet battery interchangeability across your job site.

Q4: How does the brushless motor improve working performance?

A: Brushless motors run cooler, consume less power per cycle (extending battery runtime by up to 50%), provide higher torque-to-weight ratios, and require zero brush replacement maintenance.

Q5: What is the MOQ and lead time for OEM private labeling orders?

A: The standard MOQ for custom housing colors, private labeling, and custom BMC box packaging is 300 to 500 sets per model, with typical production delivery within 35 to 45 days.
