I use a rotary dial speed control intended for routers and commonly available from woodworking suppliers. Inexpensive and seems to work fine with my Milwaukee die grinder Do you think there would be any advantage to a pedal like a Tig welder or Foredom tool would have?
@@jimurrata6785 There is no comparison from a rheostat type speed controller vs. Scr drive speed control. Rheostat lowers the voltage and torque with speed. That can sometimes be fine. The drive blasts the field winding with dc current pulses which produce higer torque. It just reduces the number of pulses to reduce speed.
The DW660 is a 5amp version for drywall cutout ,had one i used years ago for porting with a variable speed drive ,also considering using one of my 2 or 3hp routers to drive a 1/4" flex drive shaft from Metabo . The old stuff is much more durable than the plastic tools we have today. I have an old Black and Decker (now Dewalt) 1/2"drill (all metal construction) of my dads that is 50plus years old that if you don't hold on to it correctly you will have to have stitches or a broken arm as a result. Good info on this channel Charlie
I'm glad I bought the 887 its geat for what I'm doing of course the shanks seemed to fit tight in mine I didn't get one in all the way 1 time and you know what happened it bent the bent on the Burr. Thanks for the videos
Nice. Hmmm I was 4 h ago in a store looking a grinder. There was plastic makita and offered metabo+flex shaft. I notice there was 1/8 inch adapter but don't know does the 1/4 burr fit example into 6mm metabo? Yea the speed is controversial, but less rpm makes it more safe and controlled. Its problematic when the burr cut only one direction.
Metabo make a nice 4.7A variable speed (7-29.000 rpm) die grinder with soft start. Model GP3V The plastic Makita is too light duty for iron but might be okay in aluminum. (they have a heavier model, GDO800C that is variable speed)
@@jimurrata6785 Thanks. Im waiting metabo ge 710 compact+mounting fixture and 8mm flex cable to arriwe. Maybe i look a longer "nose" version later for a second grinder.
@@juhanahuovinen If a 6mm collet won't tighten down on your 1/4" carbide burrs it might not be too difficult to source one from North America or GB. I ran into the 6mm collet reducer issue with a Makita plunge router I sourced from Japan back when before they gained popularity here in the '80's. I will check for a part number you can reference.
@@jimurrata6785 local dealer ordered 1/4 and 1/8 collects for the flex cable and 8mm collect to machine to fit the cable. Got the machine and cable around 400€ from ebay.
Charles I'm not being a smart ass. But could you please show us on the bigger grinders how you can hold on and make your cuts. It looks like it would be very difficult Thanks for the videos
I forgot to mention the monster Dewalts are 19,000 rpm which is still way too fast so they all need speed control.
Sorry to bother, How do you control the speed?
I did a video on that. Kb electronics scr dc motor drive with potentiometer.

Dude, you have been reading my mind. Just last nite I was contemplating asking about your grinder(s)!
So that was your thoughts I heard.
@@servediocylinderheads dunno, but I was amazed when the video popped up on my screen!

Nice to know I was looking into one of those but I have several air grinders already plus I'm kinda used to them.
Sir, what speed controller do you like??
Video of mine 12:54 long has the speed controller and demo. Kb electronics scr dc motor drive with potentiometer.

6mm is .236" so it will cover a .25" shaft. Or will it? I bet someone knows.

I know you are kidding.... right hand on trigger and left hand on front handle. Take a deep breath and give it what for.
