Nyala, you can get slitting saws with really small center holes, down to 1/2". However, they will not be as stable in the cut. Your best bet is a blade with a 1" center hole, which means the holder will be somewhere around 1-1/2" OD. So, half the OD of the arbor is 3/4", plus the 1.25" depth of cut is 2", so at minimum you will need a 4" blade or possibly a 5" blade. You want to have at least 3 teeth in the cut at all times you're looking for a blade with a lower tooth count. Hollow ground blades work fine for aluminum and the lower tooth count will help clear chips better. When you cut, take the cut at full depth and use a lot of cutting fluid to reduce binding.
Have a look at the Sierra American slitting saw holders. They work very well, have the minimal diameter needed and are fairly priced.
