Control Measures

Risk Assessment

Make sure that a trained risk assesser carries out a local risk assessment to identify the particualr risks to you and others around you before core drilling commences. Duradiamond can offer general advice on the likely risks associated with a particular type of core drilling method but not specific risks at the drilling location.

When Dry Drilling use Ontool Local Dust Extraction

For over 30 years Duradiamond has promoted dust extracted core drilling systems as a safe and efficient method of controlling cutting dust when dry core drilling. Despite this more slotted dry cores are still being used without dust extraction than with dust extraction; The onus being on the operator to protect themselves using personal protective equipment (PPE). Duradiamond Bayonet and the Multiswivel patented dust extraction accessories due to thier unique design offer one of the highest levels of ontool local dust extraction for dry core drilling on the market.

M & H Class Vacuum Cleaners

Due to their unique design Duradiamond Bayonet and Multiswivel dust extraction accessories can be used with virtually any 800 Watt or larger 240/110V vacuum cleaners available on the market. When dry coring masonry high in Silica M or H Class filtration vacuum cleaners should be used. 

Dust Suppression using Water

Duradiamond have developed a unique diamond segment called Strata which contains layered diamonds throughout the segment matrix. This allows this type of core bit to be used wet or dry with the Multiswivel wet/dry accessory on 110V core drilling machines with inline rcd protection. Were materials cannot be dry drilled then they can usually be wet drilled with the same core bit offering 100% dust suppression in the process.
