Ningbo Tongque Machinery Manufacturing Co., Ltd., operating under the FLONPRO brand, is an export-focused Cordless Impact Wrench manufacturer with 15 years of experience in corded and cordless power tools. We design, assemble and test the range in our 10,000 sq.m. facility near Ningbo and Shanghai ports in China, with annual exports between US$5 million and US$10 million. Our line is built for jobs that demand breakaway torque without air hoses or cords: automotive workshops, equipment maintenance, industrial bolting and structural steel work.
Cordless Impact Wrench Range and Application Fit
Within our Power Tools range, the cordless impact wrench family is arranged around drive size and torque class. The 350 N.m compact models are for vehicle service and general maintenance; 470 N.m dual-purpose models handle mixed shop work; 600 to 700 N.m brushless models are aimed at professional fastening; and 1000 to 1300 N.m models deliver breakaway force for rusted bolts, heavy equipment and steel framing. For crews that switch between socket sizes, we also offer 1/2-inch plus 3/4-inch dual-drive industrial variants.

If your project is centred on screw-driving and smaller fasteners, our Cordless Impact Driver range is a better starting point; for wood and metal drilling, the Cordless Impact Drill fills that role. The impact wrench family is deliberately kept separate so each tool is specified for its real fastener duty.
Workpiece and Fastener Considerations
Fastener size and grade are the first data we ask for. A corroded M16 structural bolt behaves differently from a dry M10 assembly bolt, and the same wrench can be right for one job and wrong for another. For wheel work, compact length and controlled breakaway matter more than peak torque; for flange bolting, sustained impact force and socket retention become the priority.
Breakaway torque is the force required to loosen a fastener, while fastening torque is the controlled tightening value. Both influence model selection. The 1300 N.m class is not needed for every automotive bay, but it is the right starting point for heavy equipment, steel erection and large corroded fasteners. For mixed fleets, we often propose two torque classes so crews use a lighter tool for service work and a heavier tool for breakaway.
Runtime and throughput are part of the same discussion. A service bay removing 200 lug nuts per shift needs a battery platform sized for sustained use, while a construction crew doing occasional structural bolts may be better served by a lighter kit with fewer batteries. We use that information to balance tool weight, battery count and charger configuration in the proposal.
Engineering and Configuration Approach
We configure each project around the fastening task rather than a single one-size-fits-all specification. The main variables are breakaway torque, fastening torque, drive size, impact rate, speed, tool length and weight. Brushless motor models are concentrated in the professional and industrial portion of the range, where runtime and lower maintenance matter most.
Configuration choices we confirm before quoting
- Drive size: 1/2-inch, 3/4-inch or dual-size systems for mixed socket sets.
- Torque class: from 350 N.m compact service tools to 1300 N.m maximum-breakaway tools.
- Battery platform: voltage, capacity and the number of batteries or chargers in the kit.
- Control behaviour: variable-speed trigger, high-speed mode selection and fastening-oriented control where the job requires repeatable results.
- Kit scope: bare tool, battery/charger kit, carrying case or socket accessory configuration.
For production and assembly-line use, brushless electronics give the control needed for repeatable fastening. For distributor programs, the same core tool can be configured as a bare unit or a full kit so your stock keeps a sensible price ladder.
Manufacturing, Quality Control and Compliance
We implement quality control from raw material input to finished product inspection. Raw materials, motor windings, gears, anvil steel and battery packs are checked as they enter production; subassemblies are checked before final assembly; finished tools are tested for operation, torque response and runtime. Final inspection follows customer requirements and international standards, including CE and other safety requirements for export markets.
For OEM programs, we agree on inspection points before mass production, including sample testing, torque verification and packing checks. Our 15 years of production experience and 10,000 sq.m. factory keep the manufacturing flow under our control, which supports repeatability across large orders.
Operator Safety and Jobsite Considerations
Impact wrenches transmit high shock loads, so tool balance and grip geometry affect both safety and fatigue. Operator safety starts with the right socket and a securely retained anvil. For export orders we confirm the safety-related details of the final configuration: battery latch, switch behaviour, and any required marking for the destination market.
Because these tools are used in automotive pits, outdoor construction sites and industrial plants, we keep the housing layout practical for gloved use and keep the centre of gravity as close to the hand as the battery platform allows. The final specifications, including weight, length and recommended socket type, are listed in the technical drawing we send with the quotation.
OEM, ODM and Custom Development
OEM and ODM services are part of our standard workflow. We adapt cordless impact wrenches to your brand's colour, logo, packaging and specification, and we can adjust kit contents or control details to fit a particular market or application. Because we manufacture across the broader power tool category, distributors can combine impact wrenches with related tools in one shipment and one quality system.
Custom development is not limited to colour and printing. We can evaluate changes to the battery interface, switch layout, auxiliary handle options and socket storage to meet a specific distribution channel. Every modification is documented before production so the final product matches the agreed sample.

- Fastener data: bolt size, grade or target tightening torque
- Drive size required: 1/2-inch, 3/4-inch, or both
- Battery platform: existing voltage, requested battery/charger set, or bare tool
- Expected runtime or fasteners per day
- OEM/ODM requirements: branding, colour, packaging and manual language
- Destination market and required compliance documentation
- Delivery terms: FOB, CIF, CFR, EXW or your designated forwarder
Installation, Commissioning and Maintenance
Cordless impact wrenches do not need air-line installation, but they do need a planned charging setup. For shops with several tools, we recommend a battery fleet with matching chargers so the same pack fits multiple FLONPRO tools. Before production we confirm whether the delivery should include batteries, chargers, cases and socket rails.
The most service-prone areas are the anvil, impact mechanism and switch. We keep the housing layout practical for service access, and after-sales coordinates spare parts with distributors. Regular cleaning of the anvil area and keeping battery contacts free of debris extends service life.
Delivery, Service and After-Sales Coordination
Our location in Ningbo, close to Ningbo and Shanghai ports, keeps export logistics direct. We ship under FOB, CIF, CFR or EXW and will coordinate with your forwarder for local delivery and loading; if you prefer, our logistics partners arrange sea, air or express freight. The same team that prepares the configuration stays involved after delivery, coordinating spare parts and service support for the impact mechanism, switch and battery interface.
Frequently Asked Questions
What torque range do your cordless impact wrenches cover?
Our catalogue spans compact 350 N.m models through 1300 N.m industrial models, with 1/2-inch, 3/4-inch and dual-drive configurations. We use the fastener size, bolt grade and working environment to select the closest model before quoting.
Can I order with my own brand?
Yes, we provide OEM and ODM services. We customise colour, logo, packaging and labelling, and for larger programs we can adapt controls, accessories and specification details to your market.
Which drive size should I choose?
1/2-inch is the common choice for lugs, suspension and general industrial bolting. 3/4-inch or dual-drive suits heavy structural work and larger fasteners where sockets are bigger and longer-reach sets are needed. If you are unsure, send the fastener list and we will match the drive size.
How do you control quality on export orders?
Every process is inspected during production, and finished tools receive final inspection to customer requirements and international standards. For OEM programs we agree on specific inspection points, sample testing and packing checks before shipment.
How are batteries and chargers handled?
Each model can be quoted as a bare tool, with a battery and charger kit, or with a selected accessory set. The battery platform and voltage are confirmed in the proposal so replacement batteries remain consistent across your fleet.
What do you need for a quotation?
We need the fastener application, torque requirement or bolt size, drive size, target quantity, branding requirements and destination country. With those details we prepare a configuration, product drawing and delivery terms.
