Dust is generated by many of the processes carried out in the construction industrysuch as cutting, grinding, chasing or breaking. Depending on the materials and theexposure, this can result in issues ranging from an uncomfortable work environmentto potentially serious health risks. While these issues are well known, controlling airborne dust has historically been a challenge.

Another important aspect is that dust can have a negative impact on the lifetime ofpower tools and consumables or on the working processes on the job site (non-working time or additional labour time for cleaning), which can result in reduced productivity and higher costs.

Keep dust to a minimum – with Hilti.Hilti is committed to helping you reduce the risks your workforce is exposed to, and to increase your productivity on site – with product and service solutions thatgreatly reduce exposure to dust in many everyday jobs on the construction site. It’stime to take advantage of all the benefits of Hilti dust removal systems – becausedust is a hazard and a costly issue that simply can’t be ignored.

Dust can’t be ignored.

Risks of dust

The risks presented by dust can be expressed broadly interms of environmental risks and risks to health and safety.

• Environmental risks include the risks to people who liveclose to the dust source or experience frequent exposure to it for other reasons, as well as the risks to wild plants,agriculture and crops.

• Dust can have a considerable effect on a person’s healthand may lead to serious medical disorders.

Dust’s influence on people and the environment.

Although exposure to dust may result in potentially serious health risks, it is important to understand that the risk may be driven by different factors which are not necessarily related to the use of Hilti power tools only (such as application, quality of base material,duration per day and over time, intensity, ventilation of area or the use of respiratoryprotection, to name only the most important). However, according to our corporate purpose and our core values, it is important for Hilti to inform and provide tangible andpracticable information on this topic.

Type of dust

• Inhalable dust:Finds its way into the mouth and nose

• Thoracic dust:Reaches the upper respiratory area

• Respirable dust:Also reaches the finest parts of the lungs (alveola)

Hilti tools are not just cleverly designed – they’re revolutionary, highly efficient anddeliver top performance. The DG-CW 125 diamond cup wheel is a perfect example.The special design of these cup wheels provide effective dust removal, optimumcooling of the segments and top working comfort. Materials such as tile adhesive can be removed and the underlying surface prepared in a single operation. Hilti cupwheels combine maximum performance with minimum dust emissions to form a proven system that saves time and costs again and again.

The low-dust generationAir turbulence and air flow are defined exactly by the special boomerang shape of thediamond segments – for best possible dust removal performance.

Optimum dust reductionbegins with the consumable.


Four-way helical flutesHilti TE-C3X hammer drill bits feature four carbide cutting edgesand innovative X-geometry. Eachcutting edge leads into its own helical flute, ensuring extremely efficient removal of dust and fragments, thus contributing toHilti’s legendary drilling performance.

Built-in air channelsThe new Hilti DD-B core bit generation is simply in a class of itsown. In addition to this obvious,measurable drilling performanceadvantage, these core bits featurebuilt-in DRS air channels that extract the dust right at its source,from inside the core bit, for efficientcollection by the dust removal system.

Cleverly positioned holesHilti sanding sheets feature an extremely tough, hard grit for topsanding performance and extra-longlife. Their special coating greatlyreduces clogging with paint dust andcleverly positioned holes in the sheetresult in immediate and effective dustremoval.

It’s the details that count.

The Hilti DCH 300 diamond cutter is an example of dust-reducing power tool design in perfection. With its ability to cut to depths of up to 120mm and advanced ergonomicdesign, it completely redefines this tool category. The way in which the speciallyshaped hood works together with the disc to capture the dust the moment it is generated, ready for immediate removal, is amazing. It greatly reduces the health risks associated with this type of work. But that’s not all. This exceptional dustremoval efficiency also extends the life of the cutting disc, improves its cutting performance and therefore raises productivity.

Aerodynamic hood design Thanks to the new disc rotation direction and aerodynamic dust hood design, dustdoesn’t stand a chance.

Spectacular power tool design helps put an end to the dust problem.

High-tech insideThe Hilti DG 150 offers unmatchedgrinding performance. The main reason for this is its advanced engineering and the resulting optimisation of the air-flow inside thetool’s built-in dust removal hood – for extraction of dust through theopenings in the cup wheel.

Bad news and goodnewsFirst the bad news: Slitting work, alsoknown as chasing, generates a hugeamount of dust. Now the good news:With the Hilti DCH 180-SL chasingtool, dust is removed right at itssource. Quickly, cleanly and reliably.This is yet another example of howHilti tools – in conjunction with Hiltivacuum cleaners – are capable ofmaintaining a virtually dust-free working environment.

Clean cutSawing always produces sawdust.While cutting at depths of up to 70mm with the Hilti WSC 70-A36 cordless circular saw however, youmay begin to doubt this. When connected to a Hilti vacuum cleaner,no matter whether carrying out roughor fine work, this saw’s built-in dustremoval system let’s you make aclean cut every time.

The direct alternative.The Hilti DX and GX direct fastening systems are based on a range of powderor gas-actuated fastening tools that use a self-contained energy source to drive fasteners into concrete or steel in a quick, easy, virtually dust-free operation.

Thanks to the Hilti piston principle, perfected over decades, these tools provide ahigh level of safety. The energy released by the propellant charge is transferred to the fastener, under full control, by a captive piston. The driving action ends when the piston reaches the end of its travel. 90% of the kinetic energy generated is thus dissipated within the tool.

Hilti offers alternative, virtually dust-free working methods.

Flushing with water.Fast, efficient drilling and sawing in concrete – virtually dust-free thanks to the Hilti slurryremoval system which provides exceptional operating comfort. The core bit or blade iscooled by the water and, as a consequence, the drilling or sawing process is more accurate and faster, the core bit or blade lasts longer and the operator’s exposure to dust is reduced to a minimum.

In addition Hilti offers a water recycling unit (Hilti DD-REC 1). Its built-in drilling slurryextraction system allows unrestricted use – with complete independence from externalwater supplies for maximum mobility. Use is possible even in sensitive surroundingswhere special precautions would otherwise have to be taken. Costly, time-consumingcleaning up after completing the job becomes a thing of the past.

Information and regulations.What you need to know about dust.

How is dust measured?Dust exposure is measured as a concentration, i.e. milligrams of dust per cubicmeter of air:mg/m3. Exposure limits are also defined in mg/m3. The various dust components the worker isexposed to are measured. In this way, the actual dust concentration in the air that the operatorbreathes can be measured exactly. In order to deliver reliable values, the measurement has tobe carried out over an extended time period. Usually, dust exposure is given as the “time-weighted average” (TWA), so that different periods of exposure time are accounted for. The totaltime is the 8-hour work day.

*OEL = occupational exposure limit ( ) Dust classes also suitable here

Filters for suspended matter (Europe)Applications found mainly in the field of room conditioning, e.g. clean room techniques, applications in the nuclear and pharmaceutical industries:

Differentiation between HEPA filter (high-efficiency particulate air filter) and ULPA filter (ultra low penetration air filter)

Class H (HEPA)H10 (separation efficiency >_ 85%), H11 (SE >_ 95%), H12 (SE >_ 99.5%), H13 SE >_ 99.95%) or H14 (SE >_ 99.995%)

Class U (ULPA)U15 (separation efficiency >_ 99.9995%), U16 (SE >_ 99.99995%), U17 (SE >_ 99.999995%)The design of the filter shall not allow any leakage, e.g. at the sealing. The material of the filtermust be suitable for the environmental conditions typically to be expected.

The biggest impact is achieved by using Hilti dust removal systems –optimised dust collection combined with a purpose-built vacuum cleaner for significantreduction of dust emissions.

The Control of Substances Hazardous to Health Regulations 2002 (COSHH)highlight the following exposure limits:

Inhalable Resprable Quartz withindust dust respirable dust

GB / IRE 10 mg/m3 4 mg/m3 0.1 mg/m3

Dust classification (safety vacuum cleaners)Vacuum cleaners and dust classificationIndustrial vacuum cleaners are commonly used toreduce exposure to dust on jobsites. Three differentclasses of dust have been defined:

These vacuum cleaners permit picking up dusts with OEL values (occupational exposure limits) of > 1 mg/m3.

These vacuum cleaners permit picking up dusts of the dust classes L and M with OEL values of >– 0.1 mg/m3, also hardwood dust.

These vacuum cleaners permit picking up dusts of the dust classes L, M and H with OEL values of < 0.1 mg/m3, carcinogenic dusts and dusts with germs or bacteria.
