A useful cordless impact wrench range starts with the fasteners, sockets and working conditions your customers expect to encounter. Voltage and a headline torque number are only part of that decision. Importers also need a clear drive specification, a consistent way to describe torque and an itemized tool or kit offer that can be checked against the sample.
DUPOW's DUP-IW-001 and DUP-IW-002 are both 20V cordless impact wrenches with a 1/2-inch square drive. This guide explains how to turn those shared specifications into a purchasing brief, and how to compare the quoted configurations without treating unlike torque figures as a performance ranking.
Define the job before ranking the models
Describe whether the main requirement is installing fasteners, removing existing fasteners or providing a workshop with a general tool position. Add the fastener sizes, socket set and access limitations that matter to the buyer. A distributor serving vehicle workshops may need a different demonstration brief from a business supplying assembly customers.
Keep the task description concrete. “Automotive use” covers many different joints and working spaces. Naming the intended tasks gives the sample reviewer something useful to assess and prevents a quotation from becoming a comparison of the largest available numbers.
For a project with a prescribed final tightening procedure, put that procedure in the brief. A purchasing decision should account for the complete fastening process rather than assume that an impact wrench setting documents the finished joint. The customer can then review the proposed tool within the process they actually use.
Keep the square drive and accessory package separate
Both models use a 1/2-inch square drive. Record that specification independently from the socket sizes included in a kit. A drive dimension identifies the connection to the accessory; it does not describe the range of fasteners that a distributor's retail package will cover.
List the required socket sizes, quantities, extensions and adapters as separate items in the quotation. Give each item an identity that can be checked against the sample and packing list. If the customer wants a tool-only offer, the quotation should still identify any supplied accessories rather than rely on the contents of a promotional photograph.
| Model | Product identity | Focus of the quotation review |
|---|---|---|
| DUP-IW-001 | 20V cordless impact wrench; 1/2-inch square drive; listed maximum torque 320 Nm | Keep the torque description with the value, then define the battery and accessory package |
| DUP-IW-002 | 20V cordless impact wrench; 1/2-inch square drive | Specify the requested fastening or removal task and approve the quoted torque description with the sample configuration |
The table identifies two models for review. The battery, accessories and evidence used for the buying decision belong in the individual model's order record.
Compare the same torque description
Fastening torque and nut-busting torque are different entries in a specification. A useful illustration is Milwaukee's impact-wrench technical information, which presents fastening and nut-busting performance separately. That distinction helps organize a comparison; the performance of a Milwaukee model is not a specification for a DUPOW model.
When reviewing offers, put the torque description next to the value. If one offer describes fastening and another describes removal, first request equivalent information. Keep the unit visible as well. Avoid making a numerical comparison between newton metres and pound-feet without a deliberate conversion and a matching torque definition.
The sample brief should identify the tool model, battery configuration, accessory setup and agreed task. Record the review conditions and observations together. This produces a purchasing record that can be discussed with the supplier and reused when approving a reorder.
Review controls and handling with the actual sample
Ask for a model-specific description of speed selection, direction controls and any other functions required by the sales brief. Record the functions actually offered for the selected model. A similar appearance or a shared voltage does not establish that both products have the same control modes.
For a retail listing, connect each visible control to a clear description and the corresponding photograph. This helps an ecommerce team explain the chosen model without borrowing features from another version. Where the buyer needs evidence of a particular function, include it in the sample review rather than add it as an unsupported bullet point.
Handling is also best reviewed with the proposed battery and accessory setup. Keep any weight measurement tied to its contents so a bare tool and a complete kit do not enter the same comparison column.
Freeze the tool or kit configuration
Specify the tool model first, followed by battery reference, capacity, quantity and charger version. The battery connection and complete tool-and-pack combination need their own approval. A 20V label alone does not establish compatibility between different products or brands.
The 20V platform planning guide covers how to organize packs, chargers and kit formats across a wider range. For this purchase, keep the chosen impact wrench configuration on one itemized line with the accessory and packaging details attached.
Use separate retail SKUs for offers with different contents. A tool-only package, a battery kit and a socket kit should each have an unambiguous contents list. Approve the product pictures, quotation and packing specification against that same list before preparing marketplace copy.
Prepare a comparable request for quotation
Browse the impact-wrench category to establish the current model shortlist. Then send the model references, quantities, destination market, expected fastening tasks, torque information required, battery configuration and accessory list.
Add branding, manual languages and packing requirements to the RFQ brief. An effective request gives each supplier the same configuration to price and gives the sample team the same configuration to review.
Buyer FAQs
Do both models use a 1/2-inch drive?
Yes. DUP-IW-001 and DUP-IW-002 are listed as 20V cordless impact wrenches with a 1/2-inch square drive. The socket sizes and other accessories still need to be itemized for the selected offer.
Can fastening torque be compared directly with nut-busting torque?
They describe different performance entries. Compare values with the same description and unit, and retain the model and configuration used for the review.
Does 20V mean the batteries are interchangeable?
Voltage alone does not establish interchangeability. Specify and approve the exact tool, battery and charger combination for the order.
What belongs in an impact-wrench quotation?
Include the model, quantity, intended tasks, torque description, battery and charger references, socket and accessory contents, destination, branding and packing specification.
