The BL20 is a 2,200W wet drilling unit with 4-speed control, handling core diameters from 16 to 200 mm. It weighs 5.8 kg, and brushless motor technology delivers a compact, easy-to-handle package. Bluetooth connectivity, a status LED, and a kickback stop are also built in. It is a model well suited for handheld small-to-mid-diameter work and drilling in confined spaces.

The DKS32 is a 3,200W wet/dry combination unit handling 55 to 350 mm. The soft-impact feature makes it easy to adapt to jobsite conditions even where water access is limited. It is a strong candidate for renovation, indoor, and facility upgrade work that involves coring into reinforced concrete or hard materials.

The SR75 is a 7,500W, 400V water-cooled large-diameter machine with 15-speed control, handling diameters from 150 to 900 mm. Designed for rig-mounted use, it is built to sustain high loads over extended periods. It is well suited for large wall, floor, and ceiling penetrations and large-diameter through-holes in foundations and shaft areas. A water stop and automatic feed are available as options.

WEKA Is the Right Choice for Contractors Who Want
to Source Everything from a Single Manufacturer

WEKA is well suited for contractors who want to cover their entire needs—from small-to-mid-diameter handheld work for pipe and duct penetrations in renovation projects, all the way up to large-diameter coring in structural walls and foundations—with a single manufacturer's lineup. For companies that handle a mix of dry indoor work and wet large-diameter coring, the ability to combine the DKS32 and SR75 to meet both needs puts WEKA firmly in the running.

The well-structured support network is also a compelling factor for contractors who want to plan for long-term operation including consumables, or who want to verify the maintenance and service pathway before committing to an overseas brand.

Output engineering designed for real-world jobsite usability

WEKA's diamond core drills are built around a philosophy of compact size, light weight, and high output. From a compact unit like the BL20 to a wet/dry combination machine like the DKS32 and a large-diameter powerhouse like the SR75, the lineup allows contractors to select the right balance of output and size for the conditions of each job.

Rather than simply chasing maximum horsepower, WEKA's value lies in its ability to deliver practical performance—tools that can be deployed effectively based on the operator's working posture and the available installation space.

German in-house development and a supply chain built for the long haul

WEKA develops and manufactures its products in Neubulach, Germany. The company maintains a high level of in-house production and sources 80% of its components from long-standing partner companies within a 50 km radius.

The company also has a stated policy of providing spare parts for 30 years. It is a brand that lends itself well to evaluation not only on initial product specifications, but also on the serviceability of the machine over the long term.

WEKA Maintenance & After-Sales Support Network

WEKA products are sold through specialist dealers. Maintenance is handled by authorized service workshops trained to WEKA's service standards, providing a clear point of contact for troubleshooting and inspections.

Instruction manuals can be downloaded directly from the official website. Each product page also includes a direct link to the spare parts information screen, making the maintenance pathway easy to navigate.
