Tool for straight cutting with a grinder


Hello everyone, in this instruction we will discuss how you can make interesting homemade from the grinder. With it, you can quickly cut the material, making a perfectly even cut. In addition, this design makes handling the grinder much safer, because there is a good shield installed, which almost completely covers the upper part of the cutting disc. And even when jamming the grinder you will not inflict injury on yourself. This is especially true for steel discs on wood, since it is with them that the grinder can jam, a conventional cutting disc will simply fly apart.

In addition to conventional cutting, you can also make cuts in a material of a strictly defined depth. This is very useful when you need to make grooves in the manufacture. of furniture etc. Everything is going to be quite simple, but how exactly, we will consider in more detail!


Materials and tools used by the author:


Material List:
- Sheet steel;
- a disk on a tree for a grinder;
- bolts and nuts;
- a piece of pipe;
- paint.

Tool List:
- grinder;
- drill;
- welding machine;
- spanners;
- paper, marker, drawing accessories.

Homemade manufacturing process:

Step one. Collect the shield
First of all, we will collect the shield, this is the hardest part of homemade work. A grinder will be installed on it. To make the shield, you need sheet steel. First, draw patterns on paper and cut out. Next, similarly, the details are cut out of steel.

Next, we need a crown for drilling holes. Holes need to be drilled on both sides. What is in the center of the shield will be needed to install the grinder. And the second hole is needed so that sawdust comes out of the machine. A piece of pipe is subsequently welded here.

That's all, now you can weld the shield.







Step Two Clamp for grinder
We will fix the grinder for the part where its shield is attached. We make a clamp from sheet steel by bending it on a pipe. We partially weld this part so that it bends, and it can be pulled together with a screw and nut like a clamp.

Be sure the grinder is fixed with an additional bolt so that it does not crank under load. This bolt is wrapped where the handle of the grinder is attached. We weld the corresponding ear under this bolt to the shield.







Step Three Set the shield on the base
As a basis, we need a piece of sheet steel. The shield must be pivotally mounted so that it can be raised and lowered, thereby adjusting the penetration depth of the cutting disc. The hinge can be made of a nut, a rod and two corners. We weld the whole thing and look at what happened.






Step Four Clamp
To fix the grinder at the right angle, we need a latch. The author makes it of a steel plate, making a slot under it for a bolt. The bolt itself is welded to the shield, and the plate to the base. As a result, you can now tighten the nut and fix the machine in the desired position.



Step Five A pen
To make the machine convenient and safe to use, we weld one or two nuts to the machine. They will allow you to fix the handle from the grinder on the shield.


Step Six Finishing touches
At the base, cut a slit hole under the cutting disc. It is better to make it wider so that the disc does not cling to the plate. Well, then we just have to paint everything and assemble home-made.
















So the time has come for testing. The author demonstrated the operation of the machine in the photo. It cuts the tool perfectly, clearly in line. Now it is done quickly, efficiently and safely. If you want, you can even cut under the construction line. In addition to wood, it is quite possible to cut sheet metal.

That's all, the project is over, I hope you liked the home-made. Good luck and creative inspiration, if you want to repeat it. Do not forget to share your homemade products with us.

Yes, I apologize, carefully read your question! It may partially excuse what we are discussing, after all, angle grinder, and not a saw, milling cutter, etc.
???
You yourself always require the correct terminology!

And what is wrong, or Pohmelyov pointed out incorrectly ????

Here's what I asked (even copying with a typo)))):
And temer, attention, poll:
Please bring circular saw model ("circular") with the following parameters:

And what did you answer me? About the disc? So I, like, about model I asked the saws, no?

P.S. I really look forward to indicating this very model ...
Will this fit?


Since you asked, I’ll say NO! I use only those with a maximum permissible speed of 12,200.

But, as Pokhmelev correctly noted, I asked about SAW, and not about the disc !!!
Please find at least one model of a saw for disks with the given parameters!
To me, alas, it is also not clear where the hell is that very declared “device” ??? All that is demonstrated is a protective cover with a stop, what does it have to do with stabilizing the cutting line?
Saw blade Inforce 11-01-097 is designed for cutting wood products using circular saw
Firstly, I do not demand, but Paying attention technical errors, including terminology.
Secondly, in this case there is no error, there is a reduction (instead of “circular saw” - just “saw”), moreover, this is not an article, but a comment in which it is clear what is being discussed.
Ivan_Pokhmelev,
not about the disk, but about the saw
???
You yourself always require the correct terminology!
As I understand it, Valery did not ask about the disk, but about the saw with the specified parameters.
Saw blade Inforce 11-01-097 is designed for sawing wood products using a circular saw. The teeth of the tooling are equipped with carbide taps and have a special grinding for high-quality cutting of workpieces.
Recommended speed 2500 rpm, maximum 10000 rpm.

Technical characteristics of the saw blade for wood Inforce 35441
Diameter, mm 125
Landing diameter, mm 22.2
Number of teeth 48
Purpose clean cut
Wood type

Will this fit?
Yes, the grinder is easier. on a drill, I put metal discs and stone. Well, there was no way out, or rather a tool.
Answer from the manufacturer:

Disk Issues
What happens if the drive gets into the nail or screw during operation?

We recommend that you do not use a disc on a tree with nails, however, if a nail or screw accidentally falls into the cutting area, the maximum possible damage is chips on the tooth of the disc. The grinder will not vomit from the hands and the tooth will not fly out. This can be clearly seen in our video on the Youtube channel.

Why is the GRAFF Speedcutter Drive safe?

The output of the tooth for the total diameter (body) of the disk is about 1.1 mm, due to this, the disk enters the material accurately and smoothly. Its design is similar to that of a planer. If the blade is extended 1 mm on the planer, then he will remove chips no more than 1 mm at a time.
It’s easier to keep the grinder - the speed is higher. Precisely due to this! (I speak on the basis of a lot of experience)
I can’t explain it intelligently, but somewhere on an intuitive level: you should not use disks in devices that are not designed for them!

But I completely agree with this !!! And therefore - I put saw blades on the grinder only those whose landing 22.23 (and you can’t put others)))), and whose maximum angular velocity is more than 11 000 ....
And temer, attention, poll:
Please provide a model of a circular saw ("circulars") with the following parameters:
1. Landing 22.23 mm
2. The diameter of the disc is 125 mm.
3. Max. idle speed more than 6000.

VERY WAITING FOR !!!!
Tell us, why are these disks dangerous, unlike trident ones? I think, I think, and I won’t think of why?

The fact that they DEEPLY cut in the same time than trident ...
But I, for example, cut so that the disc doesn’t cut me at all!))))
And therefore - it makes no difference to me, he will NOT cut me deep, or not deeply!)))))
Right now your namesake will come, tell me why xaxa

I’m not even going to ..))))) I have already come across those to whom it is not worth explaining PRINCIPLES ....
I myself have been working in such a circle for a long time! It is convenient for high performance and the fact that it is not afraid of nails in wood - it also cuts them like oil (Oppppaaaaa !!! And you say "the other way around")))))
..But I WILL NOT advise anyone to do this !!!
Because we need it here first of all, BRAINS !!! And without them, you can get a jerk ... And then ... This disk at 11 thousand revolutions passes through the wood in the same way as through the air - without encountering resistance !!! ... So it will pass through the fingers through the palm, etc.
And the fools who are capable of allowing this are enough !!!!
So, Dmitry, do not argue! Those who cannot - let them not cut! Let them not even try !!!
P.S. In fairness, I’ll intercede for this homemade! ))) Is it something dangerous? She’s with a stubborn table (which excludes jerks even among those who are not friends with brains - you just can’t bring it wrong !!! Know hold it tight!))))
It is clear that lower.
Are you sure about the correct layout of the force vector?
Pay attention to the height of the tooth above the blade, i.e. the depth of capture of the material by the edge of the tooth.
The drill speed is lower.
Thank you, that’s exactly what I meant.I got injured a couple of times when working with a grinder with a regular grinding wheel, if it were a saw for a circular tool, there would be nothing to write, and there was nobody! smile
I didn’t put it on a grinder (I didn’t have it as well as a jigsaw with a chainsaw and a circular saw), but I put such a disk on a drill. I saw a bunch of everything. but to be honest it was scary, a very firm hand is needed. But again, depending on what to saw. I sawed the board mostly.
Do not vomit !!! Proven by practice.

This disc is designed to work with wood, and not just wood with a grinder. Not for stationary circular, although there it can also be used, namely with a grinder (angle grinder). Do not be lazy, look at it on the Internet and look at the description of work with it.
Take into account that it does not wedge. At least I do not know a single case of jamming a TRICODE disk
Yes, and on this disc, for some reason I did not meet broken solders when meeting with a nail.
What surprised me pretty much - there is soldering! Her, it seems, was supposed to be ripped off, but ... didn’t.
And thanks to the inventor of this disc, the Bulgarian does not fly out of the hands and the sawing with this disc is smooth, without twitching or tearing.
One drawback of this disk is its cost is more expensive than the saw.

But about injuries from the saw blade on the grinder

Visual information is always stronger than many descriptions.

Can you justify ?? When a trident disk hits a nail, the grinder will not vomit from the hands ??!
This is an appeal to Korolev

Sorry, I don’t know your name!
Do not try to work with a circular saw blade installed in a grinder without being fixed by a hospital. .
The strength of the jerk is such that a person is simply not able to respond to it.
How strong he would not be.
And the more powerful the grinder, the greater the risk of self-injury. And God forbid, someone nearby.
Quote: Dmitrij
You need to think with your head.

That's right, Dmitry, you need to think with your head before you publish anything.

I advised you to look at the materials on the keywords "injuries from a grinder."
Look, this will not hurt you, but your publication will hurt those people who obey you.

You, as an adult, should not be engaged in tweaking, but in normal earnings, publishing materials that are really useful to people.

Good luck to you!

Well jam, so what? why keep it ??? He is not going anywhere. Purely a Bulgarian in the hands - yes, scary, I agree. I cut and pray. And then there’s nothing to hold on to, it will jam and the Bulgarian will fly forward, the disk rotates on me.
It cuts the tool perfectly, clearly in line

Honestly, I didn’t understand what keeps the tool on the line, only the plane of the disk? And why is the jigsaw worse? And Valery Panshin is right, God forbid not to hold the tool at the moment of jamming! I can’t explain it intelligently, but somewhere on an intuitive level: you should not use disks in devices that are not designed for them!

And what if this one jammed - it won’t tear your hands off? Or type you have time to remove your finger and this disk you will not cut it? You need to think with your head.

I have such a carbide-tipped disc. The drive is 15,000 revolutions, and on my grinder is 11,000. I cut and is still alive. If you're afraid, put a trident.

Right now your namesake will come, tell me why xaxa
DMITRIJ!
Delete your post.
You have no idea what you published. This use of the grinder is extremely dangerous for human health and life.
Not everything that is published on the Internet can be taken for use or recommended for manufacture.
I also have a grinder on which I saw (albeit extremely rare) an array of wood, wood-based panel materials. But this is only when justified by the situation.
I have it fixed tightly in a wooden pedestal.
And thus, as in your publication, it is absolutely impossible to cut a grinder held only by hands, even with an emphasis !!!!!
Not just this minute, but maybe once in a while, you have been given a very serious injury and possibly with extremely serious consequences.
Type in the search engine "injuries from the grinder." Dial-dial - the hair will stand on end.

The grinder (angle grinder) is an extremely dangerous tool. Even in spite of its small dimensions.
Equally dangerous is the grinder, which is also called a hand-held circular saw, parquet and God knows how else. And note, for a grinder - an angle grinder, and a grinder - for parquet floors, absolutely different technical data, therefore, you can not give them as a valid comparative example of one to another.
They have a completely different purpose due to their technical characteristics.

Remove DMITRIJ this stuff.
His content calls for a breach of safety.
Or borrow this material for an example of using such a saw blade with a grinder (angle grinder)


With such a disk, you can really saw both an array of wood, and sheet wood materials, and even nails caught in wood materials.
With such a disk, you can not fix the grinder permanently, but you still have to follow safety precautions.
And with this disk, it is advisable to apply the thrust, which is discussed in your article. Simply, it will be easier to cut in a straight line with him.

Good luck to you!
And think about published material. First of all, check them for the safety of users and others.

With respect to you, Valery Panshin.
