OSHA’s Crystalline Silica Standard will be in effect September 23, 2017. OSHA is issuing the standard to protect workers from exposure to respirable crystalline silica in the construction industry in order to allow employers to tailor solutions to the specific conditions in their workplaces.
The new standard has had tool manufacturers working overtime to engineer tools and too attachments that will keep us productive while meeting the dust collection requirements. Here at The Hub we will be sharing reviews and information in the coming days and weeks leading up to September 23 date showing the various tools and attachments you might consider for your own compliance. Here is our first review:
Bosch HDC100 Dust Collection Attachment
Bosch knows concrete and the tools needed to work efficiently and effectively on the plumbing & hvac job site. Whether you’re working with a Bosch Bulldog rotary hammer or nearly any other modern rotary hammer of another brand this attachment is simple to install and use and is priced right in our opinion.
We’re referring to the HDC100 as a “universal” attachment, though it’s not listed as such on Bosch’s website it will fit any modern rotary hammer with a barrel mounting neck for a standard auxiliary handle (see pic above).
The 1.5lb composite plastic dust collection attachment has a built-in depth stop with a maximum drilling depth of 4-3/4” and can handle SDS drill bits up to ¾” diameter, dry core drilling up to 3-1/8” diameter [when using the core bit adapter, included].
As seen in the video the HDC100 is very effective at collecting nearly 100% of the dust from the ½” holes drilled for the drop-in anchors, an extremely common task on any mechanical job site. The dust port can be hooked up to a 1-3/8-In. vacuum hose nozzle, or it can accommodate 1-1/4-In. or 2-In. nozzles when combined with an appropriate optional adapter.
It is important to note that the HDC100 alone is not all that is needed for compliance with the OSHA standard. The HDC100 must be connected to a HEPA rated dust collector vacuum that meets the minimum requirements of the Crystalline Silica Standard to be compliant. In the video we are using the Bosch GBH18V-26 18V EC Brushless 1 In. SDS-plus® Bulldog Rotary Hammer and Bosch VAC090A 9 Gallon Dust Extractor with Automatic Filter Clean.
We have done some online price searches and found that nearly all Bosch tool retailers are listing the HDC100 at $69-70 US, its available for purchase currently.
This is only one of many tools Bosch has engineered to meet the OSHA standard, please watch for reviews of additional tools soon here on mechanical-hub.com.
