PDC cutter Inserts
KO-Diamond dome inserts are two layered engineered products designed for high impact and wear resistant applications such as encountered in percussive drilling for oil and gas. Two layed structures have also found applications in three cone rock bits. They are available in sizes for both types of bits.

Our 3/4 inch, and 7/8 inch dome inserts have found successful application in geographical locations ranging from West and East Texas, New Mexico, Oklahoma, Arkansas, WV and NEUS regions.
Inserts are evaluated for their metallurgical features by microscopic examination of the section.Following micrographs show 1) the working layer integrity 2) the bonding between the working layer and the transition layer and 3) the interface integrity between transition layer and the carbide substrate.As can be seen in the following micrographs, the layers are homogenous and well bonded.
Layer Thickness:
KO-Diamond Hammer bit inserts are characterized by highest thickness of first layer than found in any competitive product in the market place.Typical thickness for the first layer is in excess of .045 inch and transition layer of .030 inch.

QUALITY CONTROL AND IMPACT TESTING
Inserts are manufactured under strict guideline where all high pressure and high temperature components, raw materials for inserts are regulated.All batches of inserts are checked for the following:Dye penetration to check presence of cracksThermal stability testDrop Weight Test andImpact Fatigue where inserts are subjected to impact at a rate of 20 hits per minute using a 5 Ton machine.
