A: I know a lot of electricians that due. I havnt used it much for emt personally though .
A: I've used this reamer to clean holes drilled in stainless steel so it should work fine on conduit.
A: Milwaukee indicates this reaming pen is for reaming Copper Tubing, PVC Pipe and PVC Conduit...
A: Yes my primary use is copper piping
A: the blade is not replaceable
A: The blade is not removable.
A: Yes. You just hold the handle and spin it in or outside of the tube. It reams well.... This in my opinion makes it harder to apply too much pressure and harm yourself, the tool, or the tube.
A: Yes that’s the way it works this is a great tool
A: Yes, just like the one on a copper cutter. Yuo make a small circle with the pen and the blade make a bigger circle inside the copper pipe
A: yes, one you engage the piece say the ID of a pipe you should hold onto the tool and make a circular motion with your hand and the blade rotates as it goes around the part. Wear gloves and if holding with one hand keep it back a safe distance incase the blade disengages the part.
A: Yes, the blade spins so that you don't have you turn your hand. This allows you to ream the inside of a conduit in one motion. As an electrician I use this on large conduits. Works great. I use it on pvc, emt, rigid.
A: Yes, the blade rotates freely to keep the reaming edge in line with the surface to be reamed
A: Yes, it should move freely.
A: Yes the blade spins freely, when you role around inside the pipe it will roll freely and keep grip of pen.
A: Yes, the blade does spin.
A: Yes the blade is replaceable, keep in mind they may need to be ordered from manufacturer.
A: No. It would be nice if it was replaceable. Milwaukee's website will confirm it. Does work well when prepping copper pipe for press fittings and looks professional.
A: No, the bit is not replaceable.
A: No it is not replaceable i tried pleanty times to change the blade and failed
A: Might not be replaceable i tried alot of times and failed to change the blade
A: Yes, the blades are replaceable with a 3 pack, part # 48-22-4257.
