Review: Bueno - Perfect upgrade to my homebuilt 2x72 belt grinder. I have been using skateboard wheels for the last 6 months, easy to install. Review: Very pleased. - Very impressed with all aspects of this purchase. Quality is top notch and exactly as described, very reasonably priced as well. Delivery was painless too considering item was shipped from US to UK arriving earlier than expected. Only slight issue was I really wanted metric sizes but only had to ream drive pulley out very slightly to get it on the motor shaft (5/8 to 16mm). I'd purchase from this company again without hesitation. ## Features - Application : For CNC Machined Aluminum Wheel set for 2”x72” Belt Grinders.It is widely used in parts factories, building materials factories, etc.Great for tool polishing and grinding metals, acrylic, wood and other materials. - Products include : Include drive wheel, tracking wheel and 2* idler wheel.Bolt is required to mount idler and tracking wheels(Not included) . - High quality : Made from Highest Quality Aluminum.which have a great wrap rust and corrosion resistant performance.
