## Long 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.

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.
