Question about Metabo W6-115 606111420 4 1/2" Angle Grinder

1 Answer

Disc flies off when grinder stops

We are using a threaded disc, rated at 13,000 rpm. The disc remains in tact and operates correctly until the operation is complete and the trigger is released. At that point the disc comes off the grinder and flies away from the grinder.

    Are you using the proper thread size on the wheel? Second are you securing the wheel using the spindle lock. I work on these daily and never have heard of the problem as you described. It might be worth a call to Metabo tech service. Let me know

Yes the above is correct with the question "are the threads the right size." but it can also be because u are not slowing the grinder down before stopping it. if the grinder stopps to soon the disk will stay moving. so the disk will fly off. i had the same problem with a pnuematic grinder. sometimes it is the operaters fault not the tools.

I changed grinder stone wheels and replaced with buffing wheel... now the grinder will stall when i try to buff things... what went wrong or what did i do and how can i fix it?

Buffing takes a lot of power, maybe a lot more than you expected. Bench grinders come in lots of sizes and power levels. If you have a small, or inexpensive, or fractional hp grinder, it simply isn't up to the task. By the way, rpm is also a big factor. A grinder, especially a smaller one, turns at a pretty high rpm. A given hp rating at a high rpm gives less torque than the same hp rating on a different grinder with a lower rpm. On your grinder you might get away with smaller diameter and/or narrower buffing wheels that you use very lightly. Otherwise, your grinder just isn't going to cut it.

I just bought a hand grinder from a guy but don't know how to take the disc off . it has a button u push but no nut on the disc

If there isn't an arbor nut holding the blade/disc on the grinder you have a disc with the threaded center built into it. While holding the arbor lock button down you have to turn the disc by hand until it breaks free and spins off. It may be on vary tight as it is a self-tightening thread so the disc won't come off while you use it.

I own a metabo 9-125 quick but can't don't know how to place the blade

On the silver part on top of the grinder is a button , press this button and hold it down. now turn the blade until it stops moving, this locks the blade, keep holding the button down and turn grinder over ,and turn the nut counter clockwise, and remove it , take old blade off ,put on new one .it should go over the shaft and at the bottom on a "fit" Make sure it is on the "fit". replace the nut and tighten. If you dont get the nut tight enough it will loosen while in use and the disc you are cutting/grinding with will wobble and may even come off causing possible injury .

I have a dewalt 4 1/2", 120V angle grinder. I am breaking the thin cutting wheels when I use them very quickly or I pull out the stamped metal ring in the center of the cutoff wheel. The RPM rating...

If you are using these disks you need to apply very light pressure with the angle grinder and ensure you aren't putting any side pressure on the side of the disc.
Also imagine a line at a tangent to the disk. This should be kept at a shallow angle to the work piece to prevent the edge of the metal digging into the cutting disk.
As a rule of thumb you have the correct angle when the sparks are flying at less than 30 degrees back towards you.
Also make sure the retaining flange nut on the angle grinder is the correct way around to grip the disk, sometimes the nut has to be reversed to grip grinding discs.

May i fit bigger disc on my angle grinder,its speeed is 11000 rnd.p minutes,recomended 115 mm disc.i want to fit other big disc.may i do it?will it cause any problems?

there are 3 problems you might face: 1. mechanical - disc shield (or protector) is too small for bigger disc. You can remove the shield (I do not recommend!!!) or buy bigger one (as I've did). 2. RPMs - on each disc you can find maximal speed of ourter part of the disc. It depends on disc diameter and RPMs. In case yo go from 115 to 125 at 11 000 RPM, it should be still OK. But I would not go further. Check how RPMs drops with increasing disc diameter. 3. motor overload. To handle bigger discs motor should produce higher torque. But if you are not pressing on the grinder and you frequently check temperature of grinder, it should work. I have Metabo WE14-125 - 1400W motor 125 mm disc: 1. I've bought new shield from WE14-150 - it fits perfectly 2. My grinder has adjustable RPMs, when I'm using 150 mm disc I'm not going over level 3 (out of 6) to keep RPM in safe range for the disc. 3. Metabo makes also WE14-150 which is almost same as mine, but produces more torque (3,5Nm vs 3,3Nm). But the dofference is very small so I'm not worried. Juraj

I have a brand new Grinder 230mm and now need to change the grinding disc however I cannot get the locking flange off - I have detroyed one spanner, and purchased a stronger one, but still no good. can...

Try turning it the opposite way. Instead of loosening it, you may be tightening it. Reverse threads on these machines are necessary to keep the flange from flying off by itself. Joe

Motor Speed Question

The RPM rating of the die grinder is the deciding factor in the tool’s usage. A die grinder with a lower RPM is best used for fine grinding and finishing work. Speeds lower than 10,000 RPM are best for this function. A die grinder with an RPM between 10,000 and 20,000 is great for creating rough finishes and minor buffing jobs. If the die grinder will be used to remove metal burrs or to cut metal, it must have an RPM rating of over 20,000 and a no-load speed of at least 30,000 depending on the RPM rating.

I own the super jolly model grinder

Youmay have have cross threaded the grinder!!! Stop at once! Mazzer grinders have no detents!!! Mazzer grinders are reverse threaded. The way to put on a burr carrier (the thing you screw down) is to (in this case) screw it clockwise until it click down into the threads then screw it counter clockwise. It should feel smooth and silky!

Also the mazzer grinders have 4 sprincs that push up on the burr carrier. If I recall correctly you can push down on a collar sticking up from the center of the adjusting ring to neutralize the pressure of those springs.

If I had cross threaded a grinder I would first be a bit sad. Then I would lube the threads with a touch of mineral oil, bite the bulet and back the burr carrier off. If I dinged up the threads on the carrier I would clean them up with a metric thread file, If I dinged up the threads on the reciever I would have a machien shop clean them up with a metric thread rake. Try not to remove too much metal, though with the springs stabilizing the burr carrier agains the adjusting collar a mazzer cna take more abuse of this type than most
