Build the grinder assortment around distinct wheel formats, power sources and customer tasks, then compare the features actually listed for each model. Keep corded input power separate from a cordless voltage label and from unmeasured working performance.
A purchase-ready decision sheet
| Decision field | Purchasing record |
|---|---|
| Corded 125 mm position | DUP-AG-006 lists 750 W and variable speed;DUP-AG-020 lists 1200 W. Keep electrical version and controls attached to each model. |
| Cordless 115 mm position | DUP-AG-012 is labelled brushless;DUP-AG-032 is a separate 20V model. Both list 115 mm and 7500 rpm in the current range references. |
| Commercial step | Explain which stated feature or format changes between positions; do not claim a performance ranking from unlike fields. |
| Approval step | Model-specific accessories, market version, battery kit where applicable, labels and sample reference. |
Make each range position earn its place
If two offers cover the same task, write down the actual listed difference that a salesperson will explain. A different power input, wheel format or explicitly listed motor/control feature can define a question for sample review; it is not a measured productivity result.
For cordless positions, keep the proposed pack and charger identity with the model. The platform guide covers that approval record. The five-check importer brief covers the quotation package. Use the HSE abrasive-wheel reference for its safety background rather than as proof of a DUPOW product claim.
Start with the material and user
Define whether the range is intended for general metal preparation, fabrication, maintenance or lighter consumer work. The intended task influences the required disc family, output level, handling features and accessory set. Record these requirements before comparing quotations so that suppliers are pricing the same program.
Keep disc size and accessory compatibility together
Disc diameter affects the guard, spindle arrangement, working access and the accessories that can be approved with the tool. A 115 mm or 125 mm label should therefore be confirmed with the exact guard, flange, side handle and destination-market accessory list. Wheel choice and safe use remain the responsibility of the buyer, distributor and end user under the applicable instructions and local rules.
Compare power source and duty pattern
Corded models suit channels that value continuous availability and familiar voltage configurations. Cordless models can support mobile work and platform selling, but the battery interface, recommended pack, charger, kit format and service-stock plan must be frozen together. Do not assume that two products with the same voltage label share an approved platform.
Read speed and control features in context
No-load speed is one comparison point, not a complete performance claim. Buyers should also confirm speed-control format where offered, starting behavior, switch type, restart or overload functions where specified, ventilation, grip layout and the intended wheel family. Any feature used in marketing must be verified on the exact sample and written specification.
Representative DUPOW families
The following real product families illustrate how a range can cover compact corded, higher-output corded and cordless positions. Images and specifications refer to the current reviewed family pages; the order configuration remains subject to confirmation.

Freeze OEM and approval points
Before artwork begins, confirm the selected model, voltage and frequency, color scope, labels, manual languages, carton structure, accessories and any document requirements. Keep the approved sample, written specification and packaging record connected to the same model reference. This reduces the risk of a visual sample and the commercial order representing different configurations.
Angle-grinder RFQ checklist
- Destination market and sales channel
- Target user and principal materials
- Disc diameter and required spindle or accessory interface
- Corded voltage and frequency, or cordless platform and kit
- Switch, speed-control and starting requirements
- Guard, side handle, flange, spanner and accessory scope
- Branding, color, labels, manual and carton requirements
- Required sample, inspection and document checkpoints
- Estimated quantity by configuration
Compare the current DUPOW angle-grinder families, then use the power-tool sourcing route to send one comparable brief.
Buyer FAQs
Should input watts and battery voltage be used as one ranking?
No. They describe different fields. Compare the intended task and the model’s actual configuration before assessing the sample.
Does a list of market voltages prove a universal-input grinder?
No. Identify the exact electrical version offered and its rating label. Do not turn a catalogue list of options into an unsupported universal-input claim.
When is another SKU useful in the range?
When its stated format, features or commercial configuration serves a defined buyer need that the existing position does not already explain.
