I had a lot of old pipes and rebar to cut up and from what I read ru-vid.comUgkxPDBfLu68o58Aw85O_J-zIFfjJARBhp-3 this would be the tool for the job. Since I had never used one, I watched a couple of youtube videos and I'm so glad I did. Some really good safety tips, which I followed, and this tool did a splendid job. One good thing to know is the weight of the tool puts just about the right amount of pressure on the metal I was cutting, so I didn't have to use a lot of pressure, which is more likely to jam the tool. It made fast work of my job.
I think the bristles are not meant to wear down with the blade, they allow air to flow in so that the vacuum can work, this system needs really good airflow. The flexible part at the top is what adjusts the depth.
I put a dust shroud on my 4 1/2 grinder. Was roughing up a concrete slab to prep for self leveler. The room was a 20 square foot bathroom. I still saw that dust shooting out to the right and the room would get so cloudy I had to stop because I had no visibility. I was using a diamond cup grinder. I saw how clean yours was, there was obviously an issue with mine. I can’t figure it out though, it’s not like it’s a complicated piece of machinery… it’s a round shroud with a vacuum attached to it. It was so bad that I thought at first I might have had my shop vac blowing in stead of sucking, but it wasn’t. It had strong suction.
You need a really strong vacuum, like a 6.5 peak horsepower, or you need to have 2 Vaccum attach to the grinder to compensate. I use my with the ridgid 6 peak horsepower and is just like you say.
Haha the same happened to me a few days ago. It was painful to work in such a dusty room. I felt sick for the rest of the day. Luckily, I got my job done so let`s go next step further but never again doing that stuff.
I used a Makita VC4710 dust extractor with a fleece bag as the pre-filter, which catches all the concrete dust, allowing the pleated filters to remain unclogged.
none of my hoses ever connect properly to the sander or grinder its a joke that they dont make ones that fit... finding the adapter peice is even more of a bitch...
I remember when they passed that law, osha visited my job (I work in a block plant) and made us work an entire shift with these weird fucking contraptions strapped to our hips to monitor the amount of dust that lingers in the air. Dude gave me shit cause I ended up breaking mine and I told him good get your stupid ass toys off me now.
The entire purpose of this piece of equipment is to reduce the amount of inhaled silica dust since the dust is extremely harmful to exist as a functioning human. I had a parent who suffered from inhalation of a harmful substance. It is to protect the worker and all those around the worker. So you got monitored. Big deal. I would rather test people to make sure they are safe from harm due to exposure of a known hazard. Your other option is to wear respiratory protection when grinding. I would be pretty upset if you broke one of my pieces of equipment since they aren't cheap. and since you broke it the data collected isn't really worth anything. I like my job and I have a family to feed. It's what I do and it matters.
