Not long after presenting a new series of cutting materials for boring cast iron, MAPAL is now introducing a completely new programme of ISO indexable inserts for boring steel, stainless steel and heat-resistant cast-steel. For this range of cutting materials, MAPAL has not only developed new coatings on their in-house coating line, but also optimised the carbide substrate of the inserts.

Depending on the prevailing general conditions such as material, machine stability, coolant and clamping condition as well as any interrupted cuts, you can choose between PVD- and CVD-coated cutting materials. These differ with regard to the ductility of the carbide substrate used. CVD-coated ISO indexable inserts are the standard for all boring processes and are impressive with their high wear resistance. They offer the potential for a significant increase in the cutting speed and productivity even for dry machining. PVD-coated cutting materials are available for extreme general conditions such as an interrupted cut or unstable machine conditions because they have a particularly balanced ratio of wear-resistance and ductility and as a result guarantee reliable machining. 

In both cast iron and steel machining, significantly better results are achieved when boring with the new ISO indexable inserts than with those previously used. While a tool life increase of up to 100% is possible in cast iron machining, an average of 50% or more is more likely for steel and turbocharger machining.

Together with the special and standard ISO indexable inserts, MAPAL will also be offering the newly developed tangential ‘press-to-size’ ISO indexable inserts with the series of cutting materials. These are the inexpensive and optimum addition to the high-precision ground inserts and are used for applications with larger permissible tolerances, as is generally the case for roughing. This means that ISO indexable inserts with the appropriate cutting material for boring cast iron, steel and stainless steel are available for every requirement with regard to precision and costs.
