Description:CAT Advansys Heavy Duty and Heavy Duty A.R.M. tips, such as this, include approximately 60% more wear material in the tip body. The A.R.M. wears around the profile to increase penetration. Abrasion Resistant Material (A.R.M.) is a welding process that bonds very hard tungsten carbide particles to Cat G.E.T. to create a protective shield over the component. Typically, the A.R.M. process doubles the wera life - and can last even longer in some applications.Application:Low impact and Highly abrasion conditions.
