No. Only recommended for copper and PVC. The blade is heat treated but is not carbide.

Makes short work of cleaning up cut ends of copper tubing (for water lines). Completely eliminates the sharp, thin flange-like material produced on the inside surface of the pipe when cut with a tubing cutter. Fast and easy to use. Wish I'd known about it 20 years ago. Saves lots of time. Not expensive. Highly recommended.

Rated 4 out of 5 by from Handy and compact There are both good and bad aspects of this tool, but the good ones certainly outweigh the bad. This tool is compact. Most higher end reamers are bulky and don't have the ability to just slip into your shirt pocket. This little guy is about the size of a pencil. It has a high quality bit and the movement is pretty decent. There is also a shirt clip attached to the handle to allow you to clip it to whatever you have to carry it around with. The bad... The bit is not interchangeable as far as I can tell. Start working on harder materials like steel, tungsten or ceramic and you will wear this guy out pretty quick. The only option is to buy a new one. But if you regularly use it to work with brass, copper, aluminum, plastics, etc. then you should be able to see some long life from this compact little workhorse.

Rated 4 out of 5 by from A handy tool for cleaning pipe I'm not a professional plumber but I do work with PVC around the house for plumbing and fish pond projects. In addition to cutting pipe I drill a lot of holes for strainers and drainage with PVC. Rounding off corners has always been a problem. I don't want the sharp edges left from drilling or cutting, but never had a good quick fix. Enter the reaming pen. Quick, effective, simple to use. Put the cutter end in the pipe or hole, run it around the edge a few times, the edge is rounded over. There is a small learning curve to get the right bite on the edge to produce a smooth corner but for plumbing and fish pond work it seems fine.

Rated 5 out of 5 by from Stout design This Milwaukee "Reaming Pen" is build tough. I have used other brands before and this one holds up very well. The reaming edge is hardened so it keeps its edge very well. The handle is hex shaped so it is easy to hold on to and the head swivels so you do not have to keep repositioning the tool. It also has a smooth round end so it will not scratch if you slip when yo are reaming edges. I have used it on sheet steel and copper pipe and it works great.

Rated 5 out of 5 by from Handy little tool. Made for copper, but I used it on EMT and it works fine Place this inside the pipe, give it a quick twirl and just like that you have clean ends to your copper or steel pipe. I've been working on a prototype for a small glockenspiel (think Xylophone) made from EMT (conduit pipe). The project requires lots of precision cut lengths of tubing to make the "idiophones", each cut so they produce a specific note when struck with a mallet. I tried two methods of cutting, one, using a wheel type tubing cutter made for copper pipe, and the other using a finetoothed metal cutting blade in the sawzall. Both methods worked, but left a burr on the inside of the pipe. I was worried that students would get cut when they stuck their fingers into the tube. This little reamer to the rescue. It's got a sharp carbide cutter and with a few quick swirls around the inside of the tube I had nice smooth tubes that wont hurt anyone.

Rated 4 out of 5 by from Smooth Operation The reaming pen was used to de-bur cut ends of PVC and copper pipe/tube, as indicated on the packaging. A saw-cut piece of PVC pipe was used as well as a piece of copper tube, cut with a roller type tubing cutter. The ragged edges and shards of PVC were quickly smoothed fact, in PVC, the cutting action is rather aggressive, so some finesse is called for to prevent "beveling" the inside edge of the pipe. Reaming the copper tube also requires some care to avoid scoring the inside surface of the tube, which may require cleaning out the copper particles, if the application involves any components which could be adversely affected by metallic particles. Although not advertised for use on aluminum, it was successfully used to de-bur several holes drilled in an aluminum plate. All in all, a convenient tool to keep clipped in your pocket when working with any of the above materials.
