Angle grinder for cutting wood

They were certainly available long before that - but often the prices were prohibitive - partly because other than basic things like drills, much of the kit was professional level stuff not really aimed at the general public.

(That £84 would be something like £270 ($400) in today's money allowing for inflation).

You definitely want a low-viscosity blade.

If you're so sure about it perhaps you would like to demonstrate for us and get your next of kin to put the video up on U-tube.

Heh-heh, blade tip travelling at beyond even rail gun projectile hypersonic speed would be fun.

RPS = 4500rpm / 60 = 75 Circumference is 2*Pi*R = 2 * 3.14 * 0.19/2 = 0.59m Circumferential speed = 75 * 0.49 = 44m/sec.

At 4,500rpm you have almost 100 miles per hour. At 10,000rpm you have

200 miles per hour. Quite a few angle grinders run 12,000rpm, still far below the sound barrier.

Due to the way an angle grinder is mechanically driven, stopping one in motion as with a tree root will hurl the saw at speed. A chainsaw will not do this hence eminently less dangeous than a freakin angle grinder.

A chain saw Can kick back. Hence the use of face shield and helmet when using one.

Your mind is made up so I know this is a waste of time. Your wild ass statement about a diamond blade kicking back and cutting a man's neck is pure hyperbola, fiction, and prevarication. A diamond blade would be very hard pressed to cut your hand if you ran it into your hand at full speed. They do an excellent job cutting really hard things like glass and tile, they really suck on anything else.

I have no idea what an alligator saw is. I've been in the commercial contracting business for over 50 years so please enlighten me as I may need one some day.

You may not be strong enough to hang onto a grinder when the blade hits something, be it a tree root or whatever, but I sure as hell am and have done so, though that is NOT the object when using the tool.

The reason most us have said to not use the grinder with a blade has much more to do with the OP's opening line which said that he was not experienced. Let it alone.

I really hate it when people babble and pontificate about things of which they have no experience. If you have information or experience to share, have at: otherwise, sit back and listen (read).

Chain saws will most certainly kick back - as Lobby says. Very violently in fact. The face shield and helmet are of no value if they do kidk back that hard - they'll just disappear in the blood splatter. Face shields and helmets are useful for lesser flying debris but they sure as hell won't stop a chain coming at your head. Regardless - not only will chainsaws kick back - they are very well known for this capability. Evidence that the previous poster knows nothing at all about using chainsaws - and all the reason to ignore his comments.

I think that is what most of the people who really understand angle grinders have been saying.

Downside??? You have to be willing to hold and use the tool properly. Anything less does not result in a "downside".

That is why they have that flexible foot on them, to press up against the work being cut. Sounds like somebody was trying to reach too far. Like any power cutting tool, you gotta plan your cut before you pull the trigger. No saw works well to cut the end off a spring hanging in mid-air. That is why those tree-pruning saws on the long poles are of such limited usefulness, other than right up by the trunk or a thick main branch.

Anchor the work and use the foot.

Tip: Quick-Grip clamps are crap for anchoring work you are trying to cut with a reciprocating saw. The vibration loosens the clamps and you wind up resetting them multiple times. Not that I'd know that, it happened to somebody who lives in my neighborhood.

Didn't mean to imply that the face shield or helmet would stop a chain. They might gain enough time for the chain brake to engage.

Thick branches and right up against the trunk is the Intended use.

That is what the foot is for, to stop the material being pulled forwards by the cutting stroke. You don't have to hold it tightly at all.

And you would not want your nice sharp chainsaw blade to be anywhere near grit, earth, and any bit of wood with a nasty nail therein;!...

That's why you sharpen them regularly.

Oh and as far as kickbacks go, thats why you tend NOT to out your face over the blade: Always you cut soo the swaw will kick over your shoulder.

As pointed out, the mask is not there to stop a saw blade. Flying chips only.

Never mind the "graphic" bits the text is bad enough;!....

"A thorough secondary survey should be performed in the situation of a shattered disc as several anatomical sites may be affected. In particular perineal or scrotal injuries occur if the operator straddles the object being cut and can be missed [2]. Overhead use of angle grinders has been associated with fatal intracranial injury and should be avoided [5]. A number of articles have been published to warn of these specific dangers [6,7]. In order to reduce the risks of injury there are general guidelines about the use of power tools such as checking they are maintained and on the use of protective clothing [7]. Specific guidance on the use of angle grinders is shown in Table 2.

What an old boss of mine would term a "slip-up" rather than a mistake :-)
