| | | composition: A high CBN content, PCBN tip brazed onto a carbide insert. application: The primary application area for high CBN content grades is in roughing to finishing of fully pearlitic gray cast iron, chilled irons, high chrome alloys steels, sintered powdered metals, and heavy cuts in hardened steels (>45 HRC). Also use for finishing chilled cast iron and fully pearlitic cast iron. Do not apply on finishing cuts in hardened steels. Available in regular size tips. | | |

| | | composition: A polycrystalline diamond tip (PCD) brazed onto a carbide substrate. application: The KD100 grade is for general purpose turning. The cutting tool material contains a binder in addition to diamond particles. This makes the KD100 grade suitable for roughing to finishing all types of highly abrasive workpieces, including non-ferrous metals and non-metallics. Use as your first choice on high content silicon aluminum alloys (hypereutectic). Will generally produce good surface finishes. Provides the best mechanical shock resistance of the diamond tool materials. The cutting edge is sharp. This grade operates at very high speeds. | | |

| | | composition: A pure CVD deposited diamond sheet tool direct brazed to a carbide substrate. application: KD1405 is Kennametal's and the industry's most abrasion resistant tool material for non-ferrous and non-metallic materials. KD1405 is best applied when abrasion resistance is the desired benefit. KD1405 is not as tough as KD100, but can withstand moderate interruptions when turning and traditional face milling operations. | | |
