As part of its Black Friday campaign, Lidl is sharply reducing the price of a cordless Parkside angle grinder, presenting it as an affordable yet capable option for home renovation projects and everyday DIY tasks. The offer is attracting attention from shoppers in France and across Europe who are looking for practical performance at a supermarket-level price.

A cordless angle grinder designed for everyday DIY needs
The highlight of the promotion is the Parkside PWSA 20-Li D4, a cordless angle grinder powered by a 20 V lithium-ion battery with a 4 Ah capacity. This setup provides enough runtime for common jobs such as cutting, grinding, and brushing materials like metal, stone, or concrete around the home or garden.
Lidl positions this model around real-world DIY tasks: trimming metal pipes, cutting paving stones, removing rust from fittings, or smoothing welds and sharp edges. Rather than a bulky trade-grade tool, it is intended as a compact, grab-and-go machine suitable for occasional projects.
During Black Friday, the grinder is priced at €44.99, reduced from €54.99, while stocks last in Lidl stores.
Although the €10 saving may seem modest, in the budget power-tool segment even small price drops can strongly influence buying decisions, particularly when paired with features often seen on higher-tier models.
Practical features focused on ease of use
This grinder prioritizes usability and convenience over raw power. Lidl emphasizes several design choices intended to make work smoother once a job is underway.
Battery monitoring and usable runtime
The 4 Ah battery includes a three-level LED indicator, allowing users to check remaining charge at a glance before starting work. This helps avoid unexpected power loss halfway through a cut.
An integrated cell balancing system is designed to ensure even performance across battery cells, helping to slow down wear over time. This can be important for users who plan to keep the tool for several years.
- 20 V lithium-ion system for steady power delivery
- 4 Ah capacity suited to multiple short or medium tasks
- Three-stage LED indicator for quick charge checks
- Cell balancing technology to support battery longevity
Handling, comfort, and construction quality
The grinder features a compact body paired with a cast aluminium gear housing, offering solid resistance against impacts and metal dust. This is particularly useful when working in tight spaces or on hard surfaces like concrete floors.
The main grip is finished with a Softgrip, non-slip coating. For occasional users who are less familiar with angle grinders, this improves control and comfort, especially during longer cuts or overhead work.
A three-position auxiliary handle allows users to adjust their grip depending on whether they are working horizontally, vertically, or at awkward angles.
Lidl also highlights a tool-free adjustable disc guard. Being able to reposition the guard quickly encourages safer use, as users are less likely to remove it altogether when adjustments are easy.
Variable speed, accessories, and flexible use
Unlike many entry-level grinders that operate at a single speed, the Parkside PWSA 20-Li D4 offers six selectable speed levels. This makes it easier to adapt the tool to different materials and accessories.
Adapting speed to different materials
Variable speed control allows users to match performance to the task:
- Metal: higher speeds for cutting pipes, brackets, and angle iron
- Stone and concrete: moderate speeds for trimming slabs or blocks
- Masonry and brick: controlled cutting with diamond discs
- Paint and rust removal: lower speeds with wire wheels for improved handling
The grinder supports standard 125 mm discs, which are widely available and strike a balance between cutting depth and portability.
In addition to cutting and grinding discs, it can also be fitted with cup brushes and circular wire brushes, making it useful for cleaning and surface preparation tasks such as refurbishing railings or gates.
Disc changes, storage, and everyday convenience
Disc changes are handled via a spindle lock system, a familiar feature on modern grinders. A practical addition is that the tightening key stores directly in the front handle, reducing the chance of misplacing it.
The grinder is supplied in a dedicated storage case, making it easier for occasional users to keep the tool, battery, charger, and accessories together rather than scattered around a garage or storage space.

Who this cordless grinder is best suited for
This promotion clearly targets home users and casual DIYers rather than full-time professionals. Those who regularly cut thick steel or work for extended periods may still prefer heavy-duty trade models.
For homeowners installing gates, trimming tiles, or cutting metal posts, a cordless grinder offers clear advantages. There is no trailing cable, no need to find a nearby socket, and less risk of damaging extension leads.
For occasional tasks, the combination of adjustable speed, compact design, and a sub-€50 price point can be more appealing than higher wattage alone.
The shared 20 V battery platform may also appeal to users who already own other Parkside cordless tools that use compatible batteries.
Safety considerations and responsible use
Angle grinders are versatile but can be intimidating for beginners. High-speed discs require careful handling.
Users should wear protective eyewear or a face shield, along with gloves and hearing protection. Sparks from metal cutting can travel far, so it is important to work away from flammable materials and vehicles.
The variable speed function can help new users maintain better control, especially at lower settings. Keeping the guard properly positioned further reduces the risk of injury if a disc fails.
Everyday situations where the Lidl grinder proves useful
For example, when refreshing a rental property, the grinder can be used to cut curtain rails, smooth tile edges, or remove old paint from balcony railings. A cordless design allows quick movement between rooms without managing cables.
In garden projects, it can help trim fencing posts, adjust metal frames, or clean outdoor furniture before repainting. The included case makes it easy to carry the full kit to a shed or driveway.
What to think about before buying during Black Friday
As with many Lidl promotions, availability depends on store stock levels and the limited Black Friday period. Buyers may also want to check battery and charger compatibility with other Parkside tools they already own.
Considering future projects is important. For heavy, frequent cutting in dense materials, a compact DIY grinder may reach its limits. For occasional mixed tasks on lighter materials, this Black Friday deal appears aimed at households looking for a simple, dependable tool ready for use when needed.
