Plumbing & HVAC

For plumbing work, the EHD 2002 Dry Diamond Drill is the trade favourite. It’s widely used by plumbing and heating engineers thanks to its high-torque 1800w motor, two-speed gearbox, and mechanical clutch. It can drill up to 152mm (6”) in brick and blockwork, making it perfect for pipe entries and larger diameter installations.

For reinforced concrete or mixed substrates, a wet & dry drill like the ETN 162/3 offers greater versatility. It can handle wet drilling up to 162mm in reinforced concrete and dry drilling up to 202mm in masonry, with integrated water and dust extraction couplings.

Yes, dry core drills can be used for HVAC installations, particularly when working in brick or blockwork. The EHD 1500 is lightweight and ideal for smaller diameter penetrations (22–82mm), while the EHD 2002 handles larger cores.

However, if pipework passes through reinforced concrete or abrasive materials, a wet & dry drill such as the PLD 182.1 is recommended, as it provides greater efficiency, cooling, and tool protection.

Plumbers typically use core bit sizes between 38mm and 127mm, depending on the pipework.

Common sizes include:

• 38mm & 52mm – for waste pipes.
• 65mm – for standard domestic pipe sleeves.
• 117mm–127mm – for larger soil pipes.

EIBENSTOCK offers a full range of dry diamond cores from 22mm up to 250mm, available in both ½" BSP and 1¼" UNC threads, covering all typical plumbing and HVAC requirements.

The EIBENSTOCK EMF 150.1 Wall Chaser is designed for chasing clean, precise channels into masonry and concrete for plumbing pipe runs and conduit. It features adjustable cutting width and depth settings, dual diamond blades, and integrated dust extraction compatibility, making it the most efficient solution for pipe installation chases.

Yes, EIBENSTOCK wall chasers can cut channels wide enough for HVAC ducting, though they are best suited for pipes and conduits. For larger ducts, multiple parallel cuts with the wall chaser followed by a breaker can be used. The EMF 150.1 provides enough power to cut into dense masonry and concrete, and when combined with a dust extractor, it ensures clean, compliant operation.

For compliance and safety, you should pair wall chasers with an M-class wet & dry extractor. These units capture hazardous dust such as silica from concrete and masonry. The EIBENSTOCK ESS 35 MP Industrial 35Ltr M-Class Extractor is the recommended companion, offering automatic filter cleaning and robust airflow to keep the cut clean, extend blade life, and protect worker health
