        Thats a good ?. I did not it carry an extra blade nor did I heard Milwaukee saying it comes with extra blade. When I bought mine I went ahead and purchased extra wheel blades on the side

          It's inside the tightening knob handle (like a washer) held in place by a Philips head screw.

              I imagine it probably could but I don't believe you'd want to use it for that

                Answer This Question

                A tube cutter like this will definitely score the glass, but the cutting blade may not last long, you'll need to heat (boiling water) and cool the glass (ice water) to complete the break after it's properly scored. Good Luck!

                    I want this to cut 1/2 - 1” EMT but would like to see if its worth it in the long run.

                    Answer This Question

                    No it will not, EMT is a harder metal than copper

                    By|Dec 4, 2023

                      It will cut other harder metals than copper, but it is hard on blades. Also you will crank down the pressure on emt witch will create a leverage issue for this mini tubing cutter. For this reason I would go to something a little bigger for the added leverage.

                        (1)

                        Sure it will, just like any pipe cutter will. Not sure how available the cutter wheels are. You need to check the outside diameter of EMT compared to copper to make sure it can cut it.

                        By|Jul 13, 2019

                          No. This is for copper tubing only.

                                Excellent cutting, stays sharp longer, great grip
                                First and foremost, I can't say enough about the tightening knob. My biggest frustration with other cutters is a round knob which it difficult to keep turning. This knob is a cinch to grab and turn. A perfect 5 out of 5. Not only perfect in that category but everything I tried with this. Another big plus is the textured paint on the tool. Again, it makes it easier to grab especially considering having a sweating hand or flux on the fingers. This makes an intense improvement in grip. Cutting as well was very decisive and clean cut. The rounding of the inside edge of the pipe was nearly non-existent, and the cutter itself stayed sharper and cleaner than most others I've used.

                                Great Mini Copper Tubing Cutter
                                Need a tube cutter for cutting at least ¾ inch and this one to be durable, sturdy and made of quality products. This has chrome rollers what will help prevent any rust. The adjust knob (Easy Grip Knob) has a two wings on it for better turning the knob when your hands are wet or slippery. The cutting capacity is from 1/8 in to 1 1/8 in. It comes with an extra blade and it does not take any tools to change the blade. Comes with a Limited Lifetime Warranty.
