Offering unparalleled manufacturing precision, Cat® cutting edges protect the blade of your machines from damage. Our Ground Engaging Tools (G.E.T) are designed specifically for the DNA of your Cat iron and deliver consistent, superior protection.
Cat dozer cutting edges provide the best balance of abrasion and impact resistance. Both Cat cutting edges and end bits are designed as a balanced system to move more material over a longer period with less downtime. This is accomplished by providing great strength for superior breakage resistance, and by offering maximum wear protection from both bottom and face wear on the cutting edge.
Manufactured from steel with properties that maintain hardness for long wear life, our durable cutting edges make it possible for your machines to deliver the performance you demand. Protect your investment by always choosing genuine Cat Ground Engaging Tools.
Attributes • Impact and abrasion resistance • High productivity in any application
Applications • Production dozing, finish dozing, and overburden removal • Straight Blades
Warning:This product can expose you to chemicals including Lead and lead compounds, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
