Product information

Description

CAT DX21B is an 18 V cordless rotary hammer with a brushless motor and an SDS Plus chuck designed for drilling and light demolition. The tool delivers up to 1210 RPM and 2.2 J impact energy, allowing concrete drilling up to 26 mm. Its battery-powered Li‑Ion operation removes the need for a power cord, while a compact design and a weight of approximately 3.25 kg support mobility on construction and renovation sites.

Advantages

The brushless motor increases efficiency and reduces maintenance compared with brushed alternatives, improving runtime on a single battery charge. SDS Plus compatibility ensures quick and secure bit changes for common masonry and concrete applications. With a maximum 2.2 J impact energy and 1210 RPM rotational speed, the rotary hammer balances drilling speed and per-stroke impact for effective drilling up to 26 mm in concrete. The cordless configuration provides freedom of movement for use in locations without mains power.

Suitable for

  • Drilling holes in concrete, masonry and brick up to 26 mm diameter
  • Light chiselling and surface removal tasks on renovation sites
  • Indoor and outdoor jobs where a cordless rotary hammer is required
  • Tradespeople and contractors needing a compact, mobile demolition/drilling tool

When it may not be suitable

The CAT DX21B is intended for drilling and light chiselling; it is not designed for prolonged heavy demolition or continuous high-load applications typical for larger corded demolition hammers. For drilling diameters greater than 26 mm in reinforced concrete or for extensive demolition work, a higher-capacity tool with greater impact energy would be more appropriate.

Key specifications

  • Power supply: 18 V Li‑Ion battery (battery sold separately unless specified)
  • Motor type: Brushless
  • Chuck type: SDS Plus
  • Maximum rotational speed: 1210 RPM
  • Impact energy: 2.2 J
  • Maximum concrete drilling diameter: 26 mm
  • Weight: approximately 3.25 kg
  • Product colours: Yellow, Red, Black

How to use

Fit a compatible SDS Plus bit and secure it in the chuck before inserting the battery. Select the appropriate mode (drilling or chiselling) if the tool includes a mode selector, and start with a low pressure feed to establish the hole, gradually increasing pressure as the bit engages the material. Allow the tool to perform the work; avoid excessive force which can reduce battery life and accelerate bit wear. After use, remove the battery, clean dust from vents and the chuck, and store the tool and accessories in a dry place.

What to consider before purchase

  • Check whether batteries and charger are included or sold separately.
  • Verify that SDS Plus bits and accessories you need are compatible with this rotary hammer.
  • Assess whether 2.2 J impact energy and 26 mm drilling capacity meet your typical job requirements.
  • Consider total system weight (approximately 3.25 kg) for prolonged handheld use.

Usage recommendations

For best results when drilling concrete up to 26 mm, use carbide-tipped SDS Plus masonry bits, work in short intervals to avoid overheating, and maintain a firm two-handed grip. Match battery capacity to expected workload to optimize runtime; for extended jobs, keep a spare charged battery available.

Weight: Weight of the product without packaging (net weight). If possible, the net weight is given including standard accessories and supplies. Please note that sometimes the manufacturer leaves out the weight of accessories and/or supplies.

Power source: What is providing power for the product e.g. mains electricity.
Battery
Drilling diameter in concrete (max): The maximum width of the hole which can be drilled in concrete.
26 mm
Chuck type: A chuck is a specialized type of clamp used to hold an object, usually an object with radial symmetry, especially a cylindrical object. It is most commonly used to hold a rotating tool (such as the drill bit in a power tool) or a rotating workpiece (such as the bar or blank in the headstock spindle of a lathe).
SDS Plus
Chiseling: The product includes a feature to employ a chisel, a wedge-like tool used to cut or shape e.g. wood or stone.
Yes
Hammer drilling: Also known as hammer drilling, this is use of a rotary drill with a hammering action. The hammering action provides a short, rapid hammer thrust to pulverize relatively brittle material and provide quicker drilling with less effort. These tools are usually electrically powered, and increasingly powered by batteries. The same technology is also used in electric "demolition hammers", also known as "chipping guns" or "breakers".

Drilling: The device features the option to drill with it, i.e. bore a hole in hard materials using a bit for rotating abrasion.
