DCK 20V MAX String Trimmers

DCK 20V MAX String Trimmers are cordless grass-trimming tools within the DCK 20V MAX outdoor power equipment system. The current European range includes the DCK KDST20152 20V MAX Cordless Brushless String Trimmer, designed for trimming grass along lawn edges, around trees, fences, paths and other areas that can be difficult to reach efficiently with a lawn mower. DCK equips this model with a brushless motor, dual cutting line, two speed settings and an adjustable cutting width.

The KDST20152 uses the DCK 20V MAX battery platform, connecting the grass trimmer to the same broader cordless ecosystem used by compatible DCK power tools and outdoor equipment. It is available both as a battery kit and as a bare-tool version, making the category relevant both for customers entering the DCK cordless system and for users who already own compatible 20V MAX batteries and charging equipment.

Unlike heavier brush-cutting equipment, a string trimmer uses flexible cutting line rather than a rigid metal blade. Its main role is controlled grass and light vegetation trimming in places where a mower cannot work accurately. DCK separately lists string trimmers, multi-head systems and brush-cutter attachments in its outdoor equipment catalogue, so these product types should not be treated as interchangeable.

DCK KDST20152 20V MAX cordless brushless string trimmer

The current DCK 20V MAX String Trimmer category is centred on the KDST20152. The manufacturer specifies several features intended to make the machine adaptable to different lawn-maintenance tasks.

The model features:

• a brushless motor;
• two speed settings;
• adjustable 33 cm (13") and 38 cm (15") cutting widths;
• a dual-line cutting system;
• 2 × 2.0 mm cutting line;
• a rapid-reload trimmer head;
• bump-feed line advancement;
• a foldable shaft;
• an aluminium shaft;
• a bare-tool weight of approximately 2.4 kg;
• approximately 3.2 kg weight with the specified 6.0Ah battery.

These specifications apply specifically to the KDST20152 model.

Brushless motor

DCK specifies a brushless motor for the KDST20152. Brushless motor construction eliminates conventional carbon brushes and is commonly used in modern cordless outdoor equipment where electronic motor control, durability and efficient battery use are important.

For this model, DCK specifically presents the brushless motor as a high-performance solution intended for efficient and durable trimming. Motor technology should nevertheless be considered together with cutting width, line diameter, battery capacity and the vegetation being trimmed.

Adjustable 33 cm and 38 cm cutting width

The KDST20152 can be configured for either a 33 cm or 38 cm cutting swath. This allows the user to adapt how much grass is cut during each pass.

A narrower cutting width can be useful where manoeuvrability and controlled trimming around obstacles are priorities. A wider setting covers more area per pass and may be useful when trimming larger open lawn edges or similar areas.

Cutting width should not be confused with cutting-line diameter. The KDST20152 uses two 2.0 mm lines, while 33 cm and 38 cm refer to the total cutting swath.

Dual-line cutting system

The DCK KDST20152 uses a dual-line trimmer head. DCK states that this design is intended to provide effective cutting while reducing vibration compared with its intended operating characteristics.

Two cutting-line ends rotate from the trimmer head, creating the cutting area around the tool. Correct replacement line diameter is important: DCK specifies 2 × 2.0 mm (0.080") line for this model.

Always use cutting line that meets the manufacturer’s requirements rather than assuming that any trimmer line will fit or operate correctly.

Rapid Reload and Bump Feed

The KDST20152 combines Rapid Reload line winding with a Bump Feed line-advance system.

Rapid Reload is intended to simplify loading replacement line into the trimmer head. Bump Feed allows additional line to be released from the head during operation using the head’s designed feed mechanism.

These systems are particularly relevant to customers comparing cordless trimmers because line replacement and line advancement directly affect how much interruption is required during regular garden maintenance.

Two-speed adjustment

DCK equips the KDST20152 with two selectable speed settings. The manufacturer describes this as a way to adapt the machine’s output to different grass conditions.

The appropriate setting depends on the vegetation and working conditions. Lighter trimming may not require the same operating level as denser grass. Battery consumption can also vary with workload and operating mode, so real runtime depends on how the trimmer is used.

Aluminium and foldable shaft

The KDST20152 uses an aluminium shaft, which DCK highlights as part of the tool’s lightweight construction. The shaft is also specified as foldable.

A folding design can make a long garden tool easier to transport and store. This is useful where equipment must fit into a vehicle, workshop storage system or limited garden shed space.

DCK lists the bare tool at approximately 2.4 kg, increasing to approximately 3.2 kg with the 6.0Ah battery specified for the HK kit.

Who are these products for?

DCK 20V MAX cordless string trimmers are relevant for customers maintaining lawns and grass areas where a mower alone cannot provide a complete finish.

Typical users may include:

• property and facility maintenance teams;
• landscape and garden-maintenance users;
• tradespeople maintaining commercial or residential properties;
• customers already using DCK 20V MAX cordless tools;
• homeowners maintaining lawn edges and grass around obstacles;
• users who prefer cordless equipment without a mains cable.

The suitability of the KDST20152 for a particular workload should be assessed against its cutting-line specification, cutting width and manufacturer instructions.

Main applications

A cordless string trimmer is primarily intended for grass and appropriate light vegetation.

Typical applications include:

• trimming lawn edges;
• cutting grass around trees;
• trimming beside fences and walls;
• working around posts and garden structures;
• trimming areas beside paths and paving;
• reaching narrow spaces that a lawn mower cannot access;
• finishing lawn-maintenance work after mowing.

A string trimmer should not automatically be treated as a replacement for a brush cutter. DCK lists brush-cutter equipment separately from its 20V MAX string trimmer.

How to choose the right DCK string trimmer

1. Check the vegetation you need to cut

String trimmers are primarily suited to grass and appropriate lighter vegetation. If the intended work involves substantially heavier growth, check whether a different class of cutting tool is required.

2. Consider cutting width

The KDST20152 offers 33 cm and 38 cm settings. A wider swath can cover more ground per pass, while the narrower configuration may be useful where control around obstacles matters.

3. Check the cutting line

DCK specifies a dual 2.0 mm line. Correct line size and installation are important for reliable operation.

4. Consider line-reload convenience

The Rapid Reload and Bump Feed systems are relevant if the trimmer is used frequently. Easier line loading and advancement can reduce interruptions during work.

5. Compare bare tool and kit

The KDST20152 is offered in at least two configurations:

• KDST20152 HK – includes one FFBL2060 6.0Ah battery and one FFCL20-04 4A charger;
• KDST20152 Z – bare tool without battery or charger.

If you already use compatible DCK 20V MAX batteries, the bare-tool version may avoid buying duplicate system components. If this is your first DCK 20V MAX outdoor tool, check whether you need the complete battery kit.

6. Think about weight

The bare tool is listed at 2.4 kg, while the HK version is approximately 3.2 kg with its specified 6.0Ah battery. Battery choice therefore affects the complete working weight.

7. Consider storage and transport

A foldable shaft can be useful for users who transport garden tools between sites or have limited storage space.

Battery and kit configuration

The KDST20152 HK package includes:

• KDST20152 string trimmer;
• FFBL2060 6.0Ah battery;
• FFCL20-04 4A charger;
• wrench;
• operator’s manual.

The KDST20152 Z version contains the trimmer, wrench and operator’s manual but is listed without a battery or charger.

This distinction is important when comparing prices or ordering online. Two products with the same basic machine may not contain the same battery-system components.

String trimmer vs brush cutter

A string trimmer uses flexible cutting line and is primarily useful for lawn edges, grass around obstacles and general finishing work.

A brush cutter is a different tool category intended for applications requiring a different cutting system. DCK lists a brush-cutter attachment separately within its outdoor equipment catalogue.

Customers should therefore select the machine according to the vegetation they actually need to manage rather than treating the terms “string trimmer” and “brush cutter” as synonyms.

Tricks & Tips

• Choose the correct cutting width for the area. The 33 cm setting can provide more controlled trimming, while 38 cm covers a wider strip.
• Use the specified 2.0 mm line. Cutting-line diameter should match DCK’s requirements for the KDST20152.
• Check which package you are ordering. HK contains a 6.0Ah battery and charger; Z does not.
• Use Bump Feed as designed. Follow the operating manual for correct line advancement rather than manually modifying the trimmer head.
• Keep suitable replacement line available. A cordless trimmer cannot cut effectively once the cutting line has been consumed.
• Use the two speed settings according to the vegetation. There is no benefit in using more output than the task requires.
• Take advantage of the folding shaft for storage. Fold or transport the tool only according to the manufacturer’s procedure.
• Inspect the cutting head before use. Make sure the line, guard and trimmer head are correctly installed and undamaged.

Safety

A string trimmer rotates cutting line at high speed and can throw grass, stones and other debris from the cutting area. Use the tool only with its required guards installed and according to the KDST20152 operator’s manual.

Wear appropriate eye protection and other personal protective equipment required for the working environment. Inspect the area before trimming and keep people and animals away from the cutting zone. Remove the battery before carrying out maintenance, handling the cutting head or replacing line whenever instructed by the manufacturer.
