This is a set of HITACHI brand chip saw blades. It includes one blade measuring 216mm (diameter) x 2.2mm (thickness) and a bonus blade measuring 216mm x 2.0mm. They are for woodworking, suitable for both crosscutting and ripping. Judging by the size, they are likely for a table saw. The 2.2mm blade appears to have been used very little, as the rotation direction indicator and numbers are clean and unworn. The 2.0mm blade shows signs of use (hence it's offered as a bonus). Please understand that the cutting performance is as expected for used items. These are used items and have been stored for a long period. Please understand and accept this, and note that returns are not accepted. Only purchase if you agree to these terms.
