ReedHycalog® is continually evaluating and developing its range of Non-Planar Interface (NPI) cutters through laboratory testing and analysis of bit run data from our extensive run information and bit performance database, BitTrak.

The ReedHycalog cutter Research and Development team continue to produce more advanced geometry to reduce internal stresses and improve impact resistance. Improvements to the chemistry of the diamond layer.

The non planar interface of the Iris Cutter consists of inclined non-radial protrusions of diamond into the carbide substrate. The protrusions are equally spaced around the cutter centre but alternate in length. The Iris Cutter features the stepped rim geometry. This cutter geometry is currently used in TReX® cutters.

The Iris Cutter incorporates a high abrasion resistant, multi-modal diamond layer. The non planar interface geometry provides impact resistance which is superior to cutters with planar interfaces. The stepped rim geometry provides a thick diamond layer at the cutting edge.

The use of Multimodal PDC, with its mix of grit sizes dramatically improved our cutters, relative wear life. Non-planar Interfaces improved both the relative toughness and the relative wear life of the cutters. In combination, the chemistry of the diamond grit mix and the NPI geometry produce cutters that are tougher and last longer than any planar interface cutter. And if you need more abrasion resistance, choose TReX cutters with the addition of the unique thermostable layer.
