For sale are 120° 4 mm diamond type flywheels. These ones are made from carbide. I also have a lot of diamond flywheels listed. I purchased a whole lot of surplus from someone who used to distribute for the alpex wheel company in New Jersey. This is all new old stock inventory though there is some mild surface rust on the shanks which will not affect actual use. For the purchase price you will be getting one cutter.
I encourage buyers to order multiples and will combine shipping just request an invoice at purchase.
