Kennametal Parting Inserts
A2™ Cut-Off • High-Performance Tools to Maximize Productivity!
The A2 platform is the ideal system for parting operations on a wide variety of workpiece materials. It works well in smooth and interrupted cuts in both wet and dry operations. Now it is available in KCU25™ for superior edge toughness and excellent wear resistance.
Innovative A2 Insert Design
• V-prisms on both top and bottom enable higher clamping force to prevent insert movement, even when cutting at high-feed rates.
• The cutting edge has a molded-in chipbreaker ramp to direct chips away from the blade, extending blade life.
• Positive rake cutting action combined with Kennametal’s high-performance PVD coatings result in superior tool life and chip control.
A2™ Insert Stop Design
• As cutting forces increase, clamping forces also increase for secure holding power.
• Fixed insert stop ensures solid seating with every index and delivers up to 30% longer life.
• Cutting height is accurately controlled for maximum reliability and performance on even small-diameter parts.
Chipbreaker Guide:
CL = Cut-Off Low Feed
CF = Cut-Off Fine
CM = Cut-Off Medium
CR = Cut-Off Rough
Grade Selection
Turning Composition: An advanced PVD grade with hard AlTiN coating and fine-grain unalloyed substrate. The new and improved coating improves edge stability with wide range speed and feed capabilities.
Turning Application: The KCU25 grade is ideal for general machining of most steels, stainless steels, high-temp alloys, titanium, irons, and non-ferrous materials in a wide range of speeds and feeds with improved edge toughness for interrupted cut and high feed rates. Hole making Composition: Advanced CVD TiCN-Al2O3 coating combined with a tough carbide substrate. Hole making Application: First choice for steel, stainless steel, and cast iron. This grade offers adequate deformation resistance, excellent edge strength, and superior wear resistance over a wide range of machining conditions for high productivity with very good reliability.
Composition: An advanced PVD-AlTiN-coated grade with a tough, ultra-fine-grain unalloyed substrate.
Application: For general-purpose machining of most steels, stainless steels, high-temp alloys, titanium, irons, and non-ferrous materials. Speeds may vary from low to medium and will handle interruptions and high feed rates.
KMF is an uncoated carbide grade, fine grained substrate for machining of high-temperature alloys and non-ferrous materials.
Composition: A multilayer PVD-TiN/TiCN/TiN-coated cermet turning grade.
Application: Ideal for high-speed finishing to medium machining of most carbon and alloy steels and stainless steels. Performs very well in cast and ductile iron applications, too. Provides long and consistent tool life and will produce excellent workpiece finishes.
