          Answer This Question

          I think this miter saw is built by Delta and branded with Rigid name and colors (compare it to the Delta 12-inch Sliding Cruzer model). My guess is that it won't be back. I don't know what the problem is, whether it's issues with performance of the saw or if it is issues between Delta and Rigid. Whatever it is, I'd be surprised if, after the length of this hiatus, it returns. We'll probably have to buy a different Rigid model or buy the Delta Cruzer.

            Answer This Question

            So they don't lose any money like most companies do is put it on sale when they only have a couple or none left i noticed that on a few items. And of course no rain checks.

              I just purchased one and in order to do a bevel cut at 45 I need to remove completely the fence If I try a bevel at 45 and miter at 45 even with no fence it doesn’t pass

              Answer This Question

              On the back side of the fence, there's a wing nut. Loosen the wing nut and slide the fencing out, away from the blade. Test your cut path, re-tighten once you have clearance. I ran into the same issue when I purchased it. Hopefully this helps.

                Bad engineering on this saw
                I didn’t even plug the saw or check out accuracy Try bevel and miter settings and are terrible needing to remove the fences in order for motor not to hit it

                  Right out of the box
                  I am replacing a miter saw that was 15 years old. I knew what I wanted but I had a budget. I have a small woodworking shop. It came down to 2 mid-priced miter saws. The price dropped on this considerably, so I jumped on it. I live 2.5 hours from the nearest Home Depot. There is no cheap home delivery. So, my wife picked it up on her way back from a trip. The only negative was she could not get any employee to help her load the box. She finally got help from a customer. Shame on Home Depot for that. This hit all the boxes for me. Right size and fits my miter saw stand (Wen Products). Dual bevel, shadow line and sliding. The specs for the price were impressive. Many are in the $500 range for all this. It was square and ready to go right out of the box. There was basically no assembly except for the side handles. I tool a test run last night and the sliding arm is smooth. All the cuts were easy and had the power for different size wood. For the DIYer this is a great buy ath the $219.00 price.

                    Works amazingly, couldn’t be happier. Got it for a great price. Does everything I want to do plus more. I’m happy that it goes flush against the wall.

                    Not Good!
                    The saw is sloppy and drifts to the right, unless depth setting is used the saw cuts into the base of the saw, bolt missing from the right side, contacted Ridgid only to find out it is made by Delta and they want me to contact Delta to get it fixed, not impressed.

                      This is by far the greatest miter saw i have ever used. It did everything i needed to with ease. Vacuum hooked right up and made almost no mess. Im not easily impressed, however this tool made my life so much more comfortable.
                      Sploosh. This saw is amazing!

                      Amazing Saw
                      I love the quality and accuracy of my saw. It is a perfect addition to my shop. The dual bevel design makes clean accurate extended cuts.

                        You can’t calibrate
                        My saw did not come true to cut. So I will need to adjust the bevel detent plate, unfortunately it is not reachable with provided T30. You can see the design flow in the image. Who designed this? Bad engineering makes useless products. Then I will have to remove the fence, it is not humanly possible, so tight and my powerful impact driver itself failed to unscrew them. I have returned the product.

                          Way cool
                          500 characters max? Bevel way off out of box. Screws hard to access--had to buy a 1/4" drive T-30 to get in there. Not as rigid laterally as I would like, both extended and not. Heavy. Carry handle seems small and flimsy. Dust collection so so--glad it has 2.25" hose adapter. Good precision and convenience, and build quality. I'm retired so it is adequate for home use. Way cool--looks like it has a Harley V-twin engine. Love the zero clearance rear.
