Greenline Agate Eater 20 inch diamond blade .135 inch width, 1 inch arbor.
This workhorse is our top selling blade. Its not beautiful and it has a little longer break in period than our other blades. Put people like it because it has a long blade life and it is great for hard materials and it is very durable which makes it popular with clubs because beginners have a hard time damaging it. Additionally it can be repaired if it gets damaged in most cases.
If you want the top surface finish and no break in time, you should consider the HPL Segmented Blade or the ThinLine blade.
