Topic tags/keywords: question

The speed control on my Hitachi M12V router quit. Can anyone tell me which wires to disconnect/connect to bypass the speed control so I have only one speed? A new speed control module costs around $110.

If you can manage it taken apart UNPLUGGED—read for an open circuit and play with meter until you find the 2 wires that make a circuit form the bunch. You should be able to connect those 2 and then used a fused power block for the try. . If you get up and running as a single speed; H-F sells a plug in speed control for about $20 or under.

Thanks. It’s my understanding that plug-in speed controls only work down to about 5000 rpm. Below that, torque drops off too much. There is a device that can vary the speed down to under 100 rpm and still retain torque. It’s called a PID and is used for speed control on CNC machines. They cost $150 and is on my wish list as I am now building a CNC router.

Can’t imagine a situation where you would need slower than 5000 rpm.. that router when working properly only goes down to 8000 rpm. You slinging some 4” bits or something??

I plan to machine aluminum, that’s why I need slower speeds.

I have 2 M12V’s…...One in a table, and one hand held….I’ve had mine for about 15-16 years, and I sure hope the speed control doesn’t go out on them….I usually run mine between 2-3 on the dial…..I buy parts I need from Tool Parts Direct….You might look them up on Google…They carry parts for all major brands, including the old model Hitachis….....Just a shot in the dark…...

I took the router apart and removed the speed control module. I spliced the 2 white wires together and taped the smaller red wire (not used). Turned it on and full speed ahead. It seems to be running faster (more noisier) than it did when the speed control was working. I’m going to get a HF speed control. I hear they work well.

I bought the HF speed control. Hooked it up and it works perfectly; actually better than before. I had a 20% off coupon which I applied and guess what! the other items I bought also were included in the 20% off. The coupon states “20% off on any ONE item”. I ended up with 5 items and 20% off on all of them.
The first thing I did was to remove the belt clip and make a mounting plate so I could attach it to the side of my router table. I had to use longer screws to attach the plate. I used a piece of sheet aluminum, 1/8” x 6” x 2-1/8”.

Could be cheaper just to replace

I used a HF speed control on a router to machine my table saw top. Worked fairly well.
