DCK 20V MAX Cordless Circular Saws

DCK 20V MAX Cordless Circular Saws are professional battery-powered cutting tools designed for fast, controlled straight and bevel cutting without dependence on a mains cable. They form part of the DCK 20V MAX Saws range, which the manufacturer positions for trade usage, combining cordless mobility with brushless motor technology and the wider DCK 20V MAX battery platform.

The current official DCK 20V MAX saw range lists two cordless brushless circular saws:

• KDMY165S (TYPE FK/BK/Z) – 165 mm circular saw;
• KDMY02-185 (TYPE FK/BK/Z) – 185 mm rear-handle circular saw.

Both models use brushless motors, reach 5000/min no-load speed, offer adjustable bevel cutting and include a dust-extraction connection. The principal differences are blade diameter, maximum cutting depth, bevel range, body configuration and weight.

165 mm or 185 mm DCK circular saw?

Blade diameter is one of the most important differences between the current DCK 20V MAX circular saws.

The KDMY165S uses a 165 mm blade with a 20 mm bore. It provides maximum cutting capacities of:

• 59 mm at 0°;
• 43 mm at 45°;
• 39 mm at 50°.

Its maximum bevel angle is 50°.

The larger KDMY02-185 uses a 185 mm blade with a 30 mm bore and provides:

• 65 mm maximum cutting depth at 0°;
• 45 mm at 45°;
• maximum bevel angle of 45°.

The 185 mm model therefore provides greater maximum straight-cutting depth, while the 165 mm KDMY165S offers a wider maximum bevel range.

Brushless motor technology

Both current DCK 20V MAX circular saws are equipped with brushless motors. DCK describes the motor systems as high-efficiency, powerful and durable solutions for demanding cordless cutting applications.

Both KDMY165S and KDMY02-185 operate at a manufacturer-specified 5000/min no-load speed.

Brushless construction is particularly relevant to cordless tools because the motor, battery, blade and electronic control system work together as a complete cutting platform. The correct saw should therefore be selected by more than motor type alone.

DCK KDMY165S – compact 165 mm circular saw

The DCK KDMY165S is the more compact 165 mm option in the current 20V MAX circular saw range.

DCK specifies:

• 20V MAX battery platform;
• brushless motor;
• 165 mm blade diameter;
• 20 mm blade bore;
• 5000/min no-load speed;
• maximum cutting depth of 59 mm at 0°;
• 43 mm cutting depth at 45°;
• 39 mm cutting depth at 50°;
• adjustable 0–50° bevel angle;
• dust collection connection;
• rubberised handle;
• approximately 3.2 kg solo-tool weight.

DCK highlights the KDMY165S's ultra-compact body as a feature intended to improve manoeuvrability in restricted working areas and at more challenging cutting angles.

This makes it particularly relevant when compact dimensions and a bevel range extending to 50° are priorities.

DCK KDMY02-185 – 185 mm rear-handle circular saw

The KDMY02-185 is the larger circular saw in the current DCK 20V MAX range.

DCK describes it as a brushless rear-handle 185 mm circular saw and specifies:

• 20V MAX battery platform;
• brushless motor;
• 185 mm blade diameter;
• 30 mm blade bore;
• 5000/min no-load speed;
• maximum cutting depth of 65 mm at 0°;
• maximum cutting depth of 45 mm at 45°;
• adjustable 0–45° bevel angle;
• reinforced aluminium-alloy base plate;
• LED work light;
• anti-restart function;
• electronic brake;
• dust collection system;
• approximately 3.5 kg solo-tool weight.

The rear-handle configuration distinguishes this model from the KDMY165S and gives users another ergonomic option depending on their preferred cutting position and application.

Cutting depth

Maximum cutting depth is a key specification when choosing a circular saw.

At 90° / 0° bevel:

• KDMY165S – 59 mm
• KDMY02-185 – 65 mm.

At 45°:

• KDMY165S – 43 mm
• KDMY02-185 – 45 mm.

The larger 185 mm model therefore provides an additional 6 mm of maximum cutting depth in a straight 0° cut.

Actual suitability for a material or workpiece depends not only on nominal cutting depth but also on the correct blade, material, cutting method and manufacturer instructions.

Bevel cutting

Both DCK circular saws allow angled cutting.

The KDMY165S offers an adjustable 0–50° bevel range, while the KDMY02-185 provides 0–45° adjustment.

Bevel capability can be useful for angled construction cuts, framing, fitting and other applications where a standard 90° cut is insufficient.

When comparing models, consider both maximum bevel angle and the remaining cutting depth at that angle.

Dust collection

Both current DCK 20V MAX circular saws feature an integrated dust port and include a vacuum adapter in the listed package contents.

The KDMY165S vacuum adapter is specified at approximately:

• inner diameter: 33 mm;
• outer diameter: 38.2 mm.

For KDMY02-185, DCK specifies approximately:

• inner diameter: 33.2 mm;
• outer diameter: 38 mm.

Connecting suitable dust extraction can help remove cutting debris from the immediate cutting area and improve visibility of the cut line.

Electronic brake and anti-restart protection

The KDMY02-185 includes an electronic brake and anti-restart function according to DCK's official specifications.

The electronic brake is intended to provide more controlled stopping of the blade after the trigger is released, while anti-restart protection helps prevent unintended restarting under applicable operating conditions.

These features are specifically listed for KDMY02-185 and should not automatically be attributed to every DCK circular saw.

Battery platform

The circular saws belong to the wider DCK 20V MAX cordless platform. DCK states that this platform spans battery capacities from 2.0Ah to 12.0Ah across its tool system.

The circular saw packages currently specified by DCK use either 5.0Ah or 4.0Ah batteries, or are supplied as solo versions.

For both KDMY165S and KDMY02-185:

• Type FK – two 5.0Ah batteries + 4A charger;
• Type BK – two 4.0Ah batteries + 4A charger;
• Type Z – saw supplied without those batteries and charger.

Type Z can therefore be particularly relevant to users who already have suitable batteries and charging equipment within the DCK 20V MAX system.

Runtime and manufacturer test data

DCK publishes the same application test reference for both current circular saws: up to 100 cuts through 200 × 40 mm pine board using a 4.0Ah battery pack.

This figure should be understood as manufacturer test data rather than a guaranteed number of cuts in every application.

Actual cuts per charge can vary according to blade condition and type, material density and thickness, cutting technique, battery condition, temperature and other working conditions.

Who are DCK 20V MAX circular saws for?

DCK positions its 20V MAX Saws range for trade usage.

Depending on the application, cordless circular saws can be relevant for:

• carpenters;
• construction professionals;
• timber-frame installers;
• roofers;
• interior installers;
• renovation teams;
• workshop users;
• maintenance professionals;
• mobile tradespeople;
• existing DCK 20V MAX users.

The cordless format is particularly useful where cutting work moves around the job site and access to mains electricity would otherwise require extension cables.

Typical applications

With the correct blade and according to the manufacturer instructions, a cordless circular saw can be used for applications such as:

• straight cutting of suitable timber;
• cross-cutting boards;
• cutting sheet materials;
• construction timber cutting;
• framing work;
• renovation work;
• fitting and installation;
• bevel cutting;
• workshop and job-site cutting.

Blade selection is essential. Blade diameter and bore must match the saw, and the blade must be approved for the material, machine speed and intended operation.

How to choose the right DCK 20V MAX circular saw

1. Choose blade diameter

The KDMY165S uses a 165 mm blade, while KDMY02-185 uses a 185 mm blade.

Choose according to required cutting depth, compatible consumables and the type of work you perform most often.

2. Compare maximum cutting depth

For maximum straight-cutting capacity, KDMY02-185 provides 65 mm, compared with 59 mm for KDMY165S.

3. Compare bevel range

KDMY165S reaches 50°, while KDMY02-185 reaches 45°.

If steeper bevel cuts are regularly required, this difference may be important.

4. Compare ergonomics

KDMY165S uses an ultra-compact body, while KDMY02-185 uses a rear-handle configuration.

The preferred layout depends on working position and user preference.

5. Compare weight

Solo-tool weights are approximately:

• KDMY165S – 3.2 kg
• KDMY02-185 – 3.5 kg.

Battery weight must be added to obtain the complete operating weight.

6. Check safety and control features

KDMY02-185 specifically lists an electronic brake and anti-restart function, as well as an LED work light.

Compare model-specific features rather than assuming that every DCK circular saw has the same electronics.

7. Check blade bore

The blade bores are different:

• KDMY165S – 20 mm
• KDMY02-185 – 30 mm.

This is essential when selecting replacement blades.

8. Choose the correct package

If you need a complete kit, compare FK and BK versions.

If you already use the DCK 20V MAX platform, Type Z may avoid purchasing additional batteries and a charger.

Circular saw or reciprocating saw?

A circular saw is generally the more specialised choice for controlled straight and bevel cuts using a rotating circular blade. A reciprocating saw uses a back-and-forth blade and is suited to a different range of cutting and demolition applications. DCK offers both within its 20V MAX Saws platform.

Tricks & Tips

• Choose blade size according to cutting depth. The 185 mm model provides greater maximum straight-cut capacity.
• Check the blade bore before ordering blades. The 165 mm and 185 mm DCK saws use different bore diameters.
• Do not judge a circular saw by blade diameter alone. Bevel range, ergonomics, weight and electronic functions also matter.
• Use dust extraction where appropriate. Both current models include a vacuum adapter.
• Support the workpiece correctly. Position supports so the cut can open naturally without trapping the blade.
• Allow the blade to reach operating speed before entering the material, according to the manufacturer's instructions.
• Use a sharp, suitable blade. A worn or inappropriate blade can reduce cutting quality and increase load on the saw.
• Check the FK/BK/Z package before ordering. Type Z does not include the battery packs and charger listed with FK/BK versions.
• Remove the battery before changing blades or making maintenance adjustments, as specified by the manufacturer.

Safety

Circular saws use exposed rotating cutting blades and require careful operation. Always follow the manual for the exact DCK model and use only blades with the correct diameter, bore, rotational-speed rating and intended material application.

Keep the saw's guards functional, support the workpiece securely and keep hands away from the cutting path. Use appropriate eye, hearing and other task-specific personal protective equipment. Before changing a blade, cleaning the machine or carrying out maintenance, disconnect the battery according to the manufacturer's instructions.
