Marcrist Dust Extraction Unit 1 1/4 INCH

The Marcrist 1 1/4 inch dust extraction unit is designed to connect your diamond core drill to a vacuum extraction system, keeping dust under control while you work. If you’ve ever drilled through concrete or masonry indoors without extraction, you’ll know exactly why this exists. The unit features a 1/2 inch BSP female connection alongside a 1 1/4 inch male connection, giving it a solid, standardised interface that works with a wide range of extraction setups.

Dust extraction during core drilling isn’t just about keeping the site tidy. Fine silica dust from concrete, brick and block is a serious respiratory hazard, and on most commercial and domestic jobs, controlling it is now an expectation rather than an option. This unit handles the connection between drill and vacuum cleanly, without improvised adapters or bodged fittings. It does what it says.

Fitting the Marcrist Dust Extraction Unit to Your Setup

The taper vacuum connector is designed to suit most standard extraction units, which makes it genuinely useful across a range of vacs rather than locking you into one brand’s ecosystem. That said, Marcrist do provide a connection flow chart that shows exactly which setups are compatible, and it’s worth checking that before you order if you’re running an unusual combination. Vacuum compatibility is one of those things that sounds simple until you’re standing on site with two fittings that refuse to meet.

Installation is quick. The unit threads onto your core drill barrel using the 1 1/4 inch male connection, then your vacuum hose attaches via the 1/2 inch BSP female port. Once set up, the extraction path is sealed and you’re pulling dust away from the cutting zone as the drill works. It keeps the area visible, reduces slurry buildup on dry cuts, and keeps your lungs happier.

This is a Marcrist own-product, item number 320.101.0055, and it’s built to the same standard as their core drills and accessories. If you’re already running Marcrist tooling, this slots into your setup without any fuss. For anyone drilling cores in occupied buildings, refurbishments, or anywhere dust is a concern, it’s one of those small accessories that makes a noticeable difference on site.
