Variable speed doesn't work on Milwaukee Magnum hammer drill

I have a Milwaukee 5370-1 Magnum hammer drill and the variable speed doesn't work. I have replaced the switch but still it operates as either on or off, no variable speed. What other part could be the culprit?

    The serial number, as least the best that I can read it is 0672101947 and I bought it the late '80's. I replaced the switch with part number 23-66-1667.

    The remote electronic part was the problem. Milwaukee has discontinued the part but I found one in stock at Toolsforless.com. It was an easy replacement and now the variable speed works perfectly! Thanks.

How new is the tool. Give me the serial number and I will come up with a solution, also what is the switch number you bought. Let me know.

    I see that you bought the right switch, I would recheck the wiring using bulletin #58-01-0074, and the parts breakdown is 54-24-0112 the only other thing it could be if it is wired correctly is the remote electronic which is actually the variable speed portion of that switch. Let me know

Troubleshooting milwaukee magnum hammer drill half inch 5370-1 672 b no power. Cord continuity is good
The only things that would cause this are a burnt out trigger switch or the motor brushes are worn out.

Milwaukee 5370 armature removal
probably need to remove the brushes from the other end as the rear bearing is bigger than the commutator section and the brushes fall in to the section and hit the bearing preventing what you want to do

When using my milwaukee m18 magnum drill halfway through drilling a hole the drill stopped as if the battery were dead
Dear Chris Kelliher, Hi,
According to your explanation, i guessed that the electronic circuit for driving the motor of drill, has gone off. In such a case, the motor is either driven under variable frequency drive system, Power transistor (FET, IGBT may be used) or SCR control circuit. under the cover of drill there is an electronic circuit, which may be damaged. It should be rectified by some technical expert. here is a link of services provider, https://www1.milwaukeetool.com/PartsAndService/Repair/Default.aspx?chrome=false
If you are unable to reach the service center just download the form from the link above an fill it and shipped your part to the related company with free shipment. If you can check it personally then check it. i will guide you whatever possible. Service Milwaukee Tool

My cordless drill is running at half RPM. Is it the brushes or the motor?
cordless drills have a switch that allows for more torque at lower rpms si in effect it is a 2 speed drill coupled with a variable speed switch that alters the rpms
If the drill is running I would be looking at a speed control problem at this point I would be looking at the torque control switch

How to replace brushes in this hammer drill
One big black plastic screw on top, one on the bottom. Unscrew them - they're brush holders. Inside are the brushes. Pull them out.

I have same problem, no variable speed control for Milwaukee 04201-1, just full speed. Is this electronic speed control as well? If so can I still get parts needed? Thanks
Variable speed on this model is controled by the switch. Part number was 23-66-2300 but it is discontinued. You may be able to use Google to search (by the part number then hit the shopping link on the left side of the page) for someone that still has one in stock.

Very common fault in power tools. You will have to see if the manufacturer can supply a new switch /speed control assembly.

When hammer drilling after drilling a few holes it stops then starts then stops then starts etc.#5370-1 magnum .i don't believe it is the cord
check the trigger switch inside the gun , a few small screws in the casing will have to be unscrewed then take the gun in half and check the trigger switch connections and possibly replace the switch I have had this problem before with no obvious signs of wear or un connected connections but then i replaced the trigger switch and it worked fine
