EJOT vortex SDS:
high performance drilling with dust removal at source

Vortex SDS is EJOT UK’s modular drilling system specifically for ‘SDS Plus’ extraction drills, designed to effectively remove the potentially harmful dust and debris created when drilling into concrete, brick and block substrates - before it reaches the air that we breathe.


What is an SDS drill?

Our German colleagues will say that Bosch invented the term ‘SDS’ and that it stands for ‘Steck-Dreh-Sitz’; ‘Plug in-Twist-Retainer’. However ‘Special Direct System’ is recognised internationally whist in the UK, ‘Slotted Drive System’ is also used - possibly because the SDS design utilises these slots to allow the drill’s hammer action to thrust the drill bit forward, retained within the slot by ball bearings. 
The back and forth motion of an SDS drill increases the strength of its action whilst reducing friction within the drill’s mechanism. This plug and twist technology reduces time spent changing tooling as the operator does not have to release or tighten the drill chuck every time. The bottom line is that an SDS Plus is an essential piece of kit for any professional regularly drilling into concrete, brick or block substrates.


Dust hazards on building sites: HSE Directives

These dense masonry substrates present a range of technical challenges but it is the airborne dust and debris that has become a focus of concern for the UK Government. The HSE’s CIS 69 document provides guidance on choosing, using and maintaining on-tool extraction to control construction site dust. 
More significantly the document highlights the legal responsibilities for employers to either prevent or adequately control ‘worker exposure’ to high levels of dust created by a variety of tasks that include cut-off saws, grinders, breakers and sanders. SDS drilling presents exactly the same potential hazard.


Inspired solutions: Dust extraction at source

It was the HSE’s guidelines that inspired EJOT’s R & D team to work with industry partners to develop Vortex SDS. The result presents the professional installer with a modular drilling system engineered from high quality materials, that creates effective dust-removal at the drilling source.
The vented four-cutter design of each carbide drill tip initiates the powerful dust extracting ‘vortex’ created inside each operating component. An integral 16amp socket connector means that the dust extraction occurs instantly, as the drill is activated and continues to draw dust and debris for a full ten seconds after drilling has finished.

The full system comprises:
4 x standard carbide tipped drill bits
8mm, 10mm, 12mm and 14mm diameters
70mm, 95mm, 120mm and 145mm lengths
1 x special drill-to-bit connector
1 x modular extension bar, 220mm length
3 x modular carbide tipped drill bits, 40mm length
Choice of 16mm, 18mm and 20mm diameters
Optional extra extension bar offers 20mm diameter holes at 450mm depth
Components can be ordered individually on a replacement basis

The removal of dust has the further time-reduction benefits of reducing friction between substrate and drill bit, thereby speeding installation and creating a more accurate drill hole. This also virtually eliminates the need to blow dust from the hole when installing mechanical anchors.
