Top Notch™ Profiling
Top Notch™ profiling inserts and toolholders stand out as the top choice for high-production profiling applications, catering to the demands of precision machining. Kennametal’s Top Notch system provides consistent tool performance, accurate indexing, and superior clamping to provide excellent surface finishing and superior tool life. The precision-ground inserts guarantee high precision indexing and lower cutting forces. The inserts are stable against alternating cutting force directions, compared with customary clamping methods and the second cutting edge is well protected against chip hammering. Whether you're working with metals, plastics, or composites, these inserts and holders prove to be a versatile solution.
