angle grinder - i could use some info

admin

Hello all- i am a student in the engineering field and am curious as to what information you have on angle grinders. any and all information is helpful. my project is to become familiar in-and-out with every aspect of angle grinders. General information: -user demographic-general applications, usages (materials cut?, tasks carried out)-issues encountered-anything you would like to change about them-i saw the thread about the angle grinder stand and found that rather interesting, so any input you like or dislike about the stand. Thanks- i have read many threads before registering and find everything enlightening. dusty
Reply:You might collect information by searching tool suppliers.  Angle grinders are used in many industries.  With the right attachments you can sand, grind and even cut.  Some wood carvers use small angle grinders to rough out their wood with special cutters mounted on the shaft.  I have used angle grinders with carbide toothed wheels to gouge and shape aluminum.  That one was a bit dangerous but highly effective.   Quality varies greatly on the machines.  Amperage rating is a good starting point when comparing power.  To ask a group welders which brand, size or power they prefer is to open a can of worms :'))

Reply:You are doing a term paper on angle grinder safety, are you?  I had that on my list of topics for my Safety Engineering I class a several years ago!  Definitely lots to talk about.  I recommended toolless guards in my paper.  Two years later, they came out and are now the norm.  I probably should've gotten a copyright.  Oh well.I have several grinders, two 4.5" DeWalts, a 7" DeWalt and two 4.5" cheap Chicago Electrics.  These are just my electric angle grinders.  I also have several air angle grinders.I keep a cutting wheel and a flap-disk wheel on the cheapies, a thin grinding wheel and a wire brush on the small DeWalts, and a heavy grinding wheel on the big DeWalt.  I also have a virtually every type of wheel available.Oh yeah, I also have another 4.5" grinder in my DeWalt 18V line-up.

Reply:thanks for the information. it's getting me started in right directions.
Reply:keep the good info coming. do any of you have the angle grinder stand?

Reply:Originally Posted by MAC702 I just like yellow...Nothing is the quality of older tools.  The best grinder in my arsenal is an old 9" Black & Decker Professional Wildcat.  Nobody has made a ginder since that is its equal.  B & D bought DeWalt to rebadge their professional line, which now of course, is nothing like the old professional line.  But they are still decent tools and worth the money.Haven't had a chance to use Metabos yet.  I hear the Ridgid is identical.

Reply:What kind of weldor are you? I saw those pictures of your tool drawers.....not a spec of dust, dirt or spatter. Those drawers were organized and clean. What's up with that? I have no organizational skills whatsoever. I am a foremans nightmare. Tools all over, cords everywhere. Air line that I trip over...it's sad. Whenever I try to set my mind to cleaning up and organizing I do it, but it only lasts until I start the next project. I envy you guys!35 years old and I still can't work neatly.But my projects come out incredibly well, so I don't beat myself up to much.Lincoln Power Mig 210MP MIGLincoln Power Mig 350MP - MIG and Push-PullLincoln TIG 300-300Lincoln Hobby-Weld 110v  Thanks JLAMESCK TIG TORCH, gas diffuser, pyrex cupThermal Dynamics Cutmaster 101My brain
Reply:They should make tool-less removal of guards, wink wink.I don't believe that older tools were made better or anything, it's just that time has sorted out which ones were good or not.  You don't see many of the crummy ones today because they all blew up long ago.

Reply:Originally Posted by MAC702You'd have to really make it obvious that you're trying to offend me before I'll take offense.  And then I'll just kill you...I've got one of those new ones (that's the D28402, right?) on order from DeWalt as we speak; free gift with the new DW871 chop saw.

Reply:I owned/ have owned 4.5 inch angle grinders by Dewald, Makita, Black and Decker, Hatachi.I prefer grinders with locking chucks rather than two wrench.  With a lock, I can usually get the wheels off with bare hand.  I prefer grinder that have switch that will lock on.  I have manuvering a grinder while holding the paddle, top or bottom. I prefer grinders that have a  flat spacer and nut, rather than a cup spacer.   and nut.  The cup spacer takes up too much space limiting how much grinding wheel can be used.  Also, my Dewalt(dw400) will not safely take cutting wheels.  First Makita I owned sucked,  small hobbiest, had a reset button that kept tripping.My favorate grinder is the 5.0amp Hitachi(g12sr), because of its low profile.  However, I just purchased a 7.5 amp Makita(9557pb) yesterday seems fine, like the high amperage little heavy but smooth.  Loaned the Hitachi to somebody,  it did not come back the same way it left (broken). The new Makita is the only grinder I purchased form a industrial tool store.  The others were purchased at Lowes or Home Depot.  I suspect there is a difference in quality. Hope this helps.Anybody,Does Home Depot/ Lowes sell the same quality tools  as industrial tool stores, comparing like model number?  Yesterday I went to look at grinders, The had a Hitachi(g12sr) with the same model number as mine though the tool stores was heavier.

Reply:I have 2 Metabo's 5" and a Hatachi 9" use the 5" for most things the big fella when the going gets tuff also use this nasty little gritter on the 5" for aluminun work used safely is fine but you need to keep your wits about you when using Attached Images

Reply:Alot of times diamond tipped saw blades are used on angle grinders.They're also used on larger gas powered cut-off saws, walk behind saws, etc. They are used for making straight cuts in just about any type of material known to man. They last alot longer than abrasive wheels too.Another type of tool used on angle grinders are Grinding Cup Wheels. These are commonly used for grinding uneven surfaces in Concrete, Granite, Stone and other similar materials.When using angle grinders with any of these tools they do tend to create ALOT of dust and since they're electric operated you can't use water as a coolant either.The best thing to do is be in a well ventilated work area and always wear safety equipment with any type of power tools (goggles, mask, etc.) If possible install some extra ventilation system to help remove the airborn dust.Hope this is the info you were looking for, good luck.Diamond Blades Man
