What is Dustless Drilling (Vacuum Drilling)?
Dustless or vacuum drilling is a technique used in the construction and mining industries to mitigate the release of dust during drilling operations, particularly when working with concrete. This process is crucial due to the health hazards associated with dust generation, especially the inhalation of crystalline silica dust, which can lead to silicosis, a serious lung disease.
In traditional concrete drilling methods, a significant amount of dust is generated due to the friction and abrasion between the drill bit and the concrete. This dust not only poses health risks but also creates a mess and can impact visibility and precision during work.
To address these challenges, dustless or vacuum drilling systems are employed. These systems integrate a vacuum attachment directly with the drilling equipment. As the drill operates, the dust is simultaneously sucked into the vacuum system, significantly reducing the amount of airborne particles.
The key components of this system include vacuum drill bits and dust extraction systems. Vacuum drill bits are specifically designed to work in conjunction with the vacuum system, ensuring that dust is efficiently captured at the source of generation.
Implementing dustless or vacuum drilling is not just about cleanliness; it's a critical health and safety measure. By significantly reducing the release of harmful silica dust, these systems protect workers from the risk of silicosis and other respiratory conditions. Additionally, they contribute to a cleaner work environment, which can enhance the efficiency and accuracy of drilling operations.
Dustless or vacuum drilling represents an essential advancement in drilling technology, offering significant health, safety, and environmental benefits. As industries continue to prioritise worker safety and environmental responsibility, the adoption of such technologies becomes increasingly important.
Types of Dustless or Vacuum Drilling
The are a few ways to reduce dust onsite while drilling. The first is to use Dustless/vacuum Drill bits. Dustless drill bits are designed for use with vacuum systems to minimise dust during drilling. They are available as SDS Plus or SDS Max Shank.
The SDS Plus Bit is suitable for smaller drills, commonly used in light to medium-duty applications. With the shank diameter being 10 mm.
- SDS Plus Dustless Drill bit
- SDS Plus Set-Safe Bionic – available in 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm,20mm and 24mm Diameters.
- SDS Plus Set-Safe Dust Extraction Kit – This kit comes with 6mm, 8mm and 10mm bits. While the SDS Max bit is designed for larger, heavy-duty rotary hammers. These bits are larger with a shank diameter of 18 mm and are used for more substantial drilling tasks.
- SDS Max Dustless Drill bit
- SDS Max Set-Safe dust Extraction – available in 14mm, 16mm, 18mm, 20mm, 22mm, 24mm, 25mm, 28mm, 30mm, 32mm and 35mm Diameters.
Another Simple solution is using a dust extraction adapter such as the ICCONS DUSTER PRO. This Dust Extraction Adaptor has entry points for the drill bit and a vacuum cleaner, creating a vacuum shroud around the drilling extracting the dust from the material surface. The device automatically adheres to the wall with vacuum suction. It is suitable to be used for use with all commonly available vacuum cleaners.
What is Dustless or Vacuum Drilling typically used for
Vacuum drill bits are an indispensable tool for construction workers tasked with drilling into concrete, especially when specific site requirements are in play. These requirements often include:
- Regulatory Compliance: Adhering to the Work Health and Safety (WHS) Act and its regulations is paramount. A critical aspect of this is managing workplace exposure to airborne contaminants, notably crystalline silica dust. This dust, a byproduct of drilling into concrete, poses significant respiratory risks. Employing dustless drilling methods, such as those offered by vacuum drill bits, is crucial in aligning with health and safety standards and protecting workers from hazardous exposure.
- Enhanced Cleanliness: The reduction of dust not only fosters a healthier work environment but also streamlines operations by minimising the need for extensive post-drilling cleanup.
Some common applications of Vacuum Drill Bits:
Vacuum drill bits have a wide array of applications in construction, making them versatile for various projects. These include:
- Steel and timber frame Hold down installation into concrete
- Installation of glazing, windows, and storefronts
- Installation of Racking, and shelving into the concrete
- Formwork and structural fixings into concrete Tunnel fit-outs, cable tray support systems, and seismic bracing of Mechanical, Electrical, and Plumbing (MEP) systems
- Fastening steel strut channels and support straps for MEP
- Construction installation of facade structures, guard rails, bollards, and protective barriers
- Installation of machinery, plant equipment, stadium and theatre seating
- Acoustic barriers, balustrades, handrails, and scaffolding ties
- Plumbing and fire services
In summary, vacuum drill bits are not just tools but a key component in ensuring safe, efficient, and compliant construction practices
Why can it be effective when used with Chemical Injection
Dustless Drilling, when combined with chemical injection, offers remarkable effectiveness. However, it's crucial to ensure that the chemical injection system you're employing is compliant with Dustless Drilling standards as stipulated in the ETA, in accordance with Australia's post-installed anchor standard AS5216. Notably, ICCONS BIS-PE GEN3 Pure Epoxy and ICCONS BIS-HY GEN3 are both certified for dustless drilling applications.
Traditionally, the preparation of holes for Chemical Injection Adhesives involves a meticulous process of brushing and blowing out debris. With Dustless Drilling, this step becomes redundant, leading to significant time savings and heightened productivity. The absence of hole cleaning in the process can make hole preparation up to three times faster when setting chemical anchors.
Additionally, the elimination of hole-cleaning materials reduces the amount of equipment needed for installing chemical anchors, streamlining the entire process.
One of the standout benefits of Dustless Drilling is the vacuum drill bit's capability to suction dust as it operates. This not only maintains a cooler drill bit, enhancing its lifespan compared to standard bits, but also minimizes the likelihood of hole-cleaning errors, as the drill itself ensures a clean hole.
Moreover, Dustless Drilling fosters a cleaner and more orderly work environment. By significantly reducing the need for extensive post-drilling cleanup, it not only boosts the efficiency of the installation process but also enhances workplace safety and organisation
How to use Dustless or vacuum drill bits
- Select the Right Drill Bit Choose a vacuum drill bit that is compatible with your drill (SDS Plus or SDS Max shank) and that is the correct diameter and length for the hole size you are drilling.
- Insert the Vacuum Drill Bit Insert the vacuum drill bit into the chuck of your drill. Make sure it is securely tightened.
- Connect the Vacuum Hose: Attach the vacuum hose to the dust extraction port on the drill. Ensure a secure connection to allow efficient dust collection
- Turn On the Vacuum System: Start the vacuum system before beginning drilling. This ensures that the dust extraction is active from the onset of the drilling process.
- Drill as Usual Drill into the material as you normally would. The vacuum system will collect and contain the dust generated during the drilling process
Who should use Dustless or Vacuum Drill bits
Dustless or Vacuum Drill Bits are essential tools for a wide range of construction professionals, including Builders, Carpenters, Plumbers, Electricians, Formworkers, Scaffold Erectors, and those in Mechanical and Electrical Services, HVAC, Commercial Contracting, and Infrastructure Contracting.
