With a continued focus on user safety Bosch has announced a larger addition to their growing lineup of vacuums & dust extractor accessories. As companies have become compliant with the OSHA silica standards the Bosch VAC090 and VAC140 have been extremely popular. Both feature auto-cleaning, tool power management and 150 CFM which means they meet requirements up to 6” cutting & grinding tools. For professionals however there continues to be a big demand for a dust collection solution for use with larger equipment 7”, 9”, 12” and larger (cutting/grinding). The GAS20-17AH ($1500) is a heavy duty monster that’ll collect dust at a rate of 300 CFM so more than enough to use with larger grinders and cutters all the way up to 12” under Table 1 (possibly even on 14” or higher but would require testing).

We of course stopped by the yellow booth at World of Concrete and they had a lot to show off this year. Dewalt is really going after the concrete market with several new products aimed at silica dust collection as well as expanding their Flexvolt cordless offering with some heavy duty tools that can now outperform their corded counter parts.
One of the tools we came to the WOC show to actually try out was the Dewalt Flexvolt 9” Concrete Saw DCS690, we first got a look at it last November at the STAFDA show however they would not let us fire it up inside the clean convention hall. Very impressive unit for going cordless, add one of those backpack water tanks and you could be very dangerous.
In 2017 we say a lot of excitement around the new OSHA Silica Dust regulations which we think is a great move forward for everyone’s safety. Silicosis is serious business but it does not necessarily need to be a complex or costly solution. The new Milwaukee DUST TRAP employs the K.I.S.S. method, keep it simple stupid. For $19 the 48-03-3035 Drill Shroud is a universal fit to most rotary drills and does not require a vacuum. Because concrete drilling does not generate significant silica dust like cutting or grinding application might simply by containing the debris in the “DUST TRAP” this attachment can meet the objective data requirements (***Permissible Exposure Limit (PEL) to 50 µg/m3 over an 8-hour period).
Two big changes have been hitting the jobsite this year, we are seeing more heavy duty cordless tools taking the places of corded tools and clouds of silica dust are being eliminated. Unfortunately these 2 things don’t seem to work together as typical dust extractors turn on/off based off the tool plugged into them. Makita wireless AWS technology looks to change that, Auto-Start Wireless System (AWS), which uses Bluetooth™ technology for wireless communication between tool and vacuum/dust extractor to turn on/off makes a cordless vac system feasible from a power usage stand point. New AWS solutions announced was teased at their event last summer but fully launched last month at STAFDA including their first Cordless SDS-MAX hammer.
Now that we are less than a month away from the September 23rd deadline we are seeing a lot more interest about the new OSHA Silica Rules which is good that people are taking this seriously. One of the big debates that has recently popped up, some manufacturers are telling their own customers that they will not support “Objective Data” and everything must be “Table 1”. This is also a commitment to not look at all the options for the safest possible solutions or to develop new tools/solutions in many key areas. The good news is OSHA (the people who make the decisions) wrote a pretty clear 26 page document §1926.1153 which provides 3 ways to be compliant for companies who will continue to innovate in this space; Table 1, Objective Data and Self-Monitoring Program.

The Bosch Speed Clean Bits have been around for a few years now, originally called the “Hollow Core” but that name probably causes confusion with actual core bits. The Speed Clean bits work differently than you traditional rotary hammer bits in that it connects to a vacuum and sucks the dust out as it drills. This makes these bits much more efficient and last longer especially when drilling at depths however it also makes the bits much more expensive to manufacturer. We have not seem mass adoption on the jobsites yet but that could all change next month (September 23rd) when the OSHA Silica Standards become enforceable. (more…)
With the new OSHA Silica Dusts rules getting ever closer there has been a lot of scrambling for manufacturers and users to get the right solutions in place. The good news is the June 23rd deadline has been pushed back 90 days to September 23, 2017 allowing for some more solutions to hit the market. Milwaukee Tool has just announced it will have a new 8 gallon HEPA dust extractor vacuum with self-cleaning filters and 148 CFM out well before the new deadline. (more…)
The original deadline for issuing OSHA fines was June 23rd however with that deadline very near the amount of unanswered questions and many tasks that still not having good solutions OSHA has announced everyone will get an additional 90 days before fines will begin. (OHSA full press release) This is good news, manufacturers of solutions to control silica dust are just now finishing testing, releasing products and as they come out are seeing immediate back orders. Training thousands and thousands of effected workers is also not an easy task and will take some time, even with the extra 90 days it will be a challenge. (more…)
