Cutting Element With Canted Design For Improved Braze Contact Area

View page
US Patent:
6405814, Jun 18, 2002
Filed:
Oct 20, 2000
Appl. No.:
09/693028
Inventors:
Ronald K. Eyre - Orem UT
Madapusi K. Keshavan - Sandy UT
David Truax - Houston TX
Assignee:
Smith International, Inc. - Houston TX
International Classification:
E21B 1046
US Classification:
175432
Abstract:
The present invention provides a cutting element having a cylindrical body having a canted end face on which is formed a ultra hard material layer. One or a plurality of transition layers may be provided between the ultra hard material layer and the cutting element body.

Engineered Enhanced Inserts For Rock Drilling Bits

View page
US Patent:
6419034, Jul 16, 2002
Filed:
Nov 7, 2000
Appl. No.:
09/707830
Inventors:
J. Daniel Belnap - Pleasant Grove UT
Ronald K. Eyre - Orem UT
Michael A. Siracki - The Woodlands TX
Per I. Nese - Houston TX
Madapusi K. Keshavan - Sandy UT
Nathan R. Anderson - Pleasant Grove UT
Assignee:
Smith International, Inc. - Houston TX
International Classification:
E21B 1056
US Classification:
175428, 175430
Abstract:
Enhanced inserts are formed having a cylindrical grip and a protrusion extending from the grip. An ultra hard material layer is bonded on top of the protrusion. The inserts are mounted on a rock bit and contact the earth formations off center. The ultra hard material layer is thickest at a critical zone which encompasses a major portion of the region of contact between the insert and the earth formation. Transition layers may also be formed between the ultra hard material layer and the protrusion so as to reduce the residual stresses formed on the interface between the ultra hard material and the protrusion.

Drill Bit Inserts With Variations In Thickness Of Diamond Coating

US Patent:
6460636, Oct 8, 2002
Filed:
Dec 17, 1999
Appl. No.:
09/465631
Inventors:
Zhou Yong - The Woodlands TX
Nathan R. Anderson - Pleasant Grove UT
J. Daniel Belnap - Pleasant Grove UT
Chris E. Cawthorne - The Woodlands TX
Ronald K. Eyre - Orem UT
Madapusi K. Keshavan - Sandy UT
Per I. Nese - Aberdeen, GB
Michael A. Siracki - The Woodlands TX
Gary R. Portwood - Kingwood TX
Assignee:
Smith International, Inc. - Houston TX
International Classification:
E21B 1046
US Classification:
175428, 175426
Abstract:
A cutter element for use in a drill bit, comprising a substrate and a cutting layer. The substrate comprises a grip portion and an extension portion, where the grip portion has an insert axis and an extension portion including an interface surface having a first apex. The cutting layer is affixed to the interface surface and has a cutting surface having a second apex. The cutting layer is shaped such that when a plane passing through the first apex and lying parallel to the insert axis and normal to a radius from the insert axis, the plane divides the cutting layer into major and minor portions and the major portion has a major volume that is at least 60 percent of the total volume of said cutting layer. Alternative embodiments of the present invention include variations wherein the first and second apices do not coincide and wherein the interface surface of the substrate is not axisymmetric. Using these variations, cutter elements having sizeable variations in thickness are constructed.

Cutting Element Having A Substrate, A Transition Layer And An Ultra Hard Material Layer

View page
US Patent:
6892836, May 17, 2005
Filed:
Dec 12, 2000
Appl. No.:
09/735389
Inventors:
Ronald K. Eyre - Orem UT, US
Madapusi K. Keshavan - Sandy UT, US
Assignee:
Smith International, Inc. - Houston TX
International Classification:
E21B010/46
US Classification:
175432, 175426, 175434
Abstract:
A non-uniform interface is formed between a polycrystalline ultra hard material layer and a cemented tungsten carbide substrate, or a polycrystalline ultra hard material layer and a transition layer, or a transition layer and a substrate of a cutting element. A first sheet made from an intermediate material is formed and embossed on one face forming a non-uniform pattern raised in relief on the face. The embossed sheet is placed on a face of a presintered substrate. An ultra hard material sheet is formed and embossed, forming a non-uniform face complementary to the non-uniform face on the sheet of intermediate material. The ultra hard material sheet is placed over the intermediate material sheet so that the complementary faces are adjacent to each other. The assembly of substrate and sheets is sintered in a HPHT process. The sintering process causes the first sheet to become integral with the substrate and results in a substrate having a non-uniform cutting face onto which is bonded a polycrystalline ultra hard material layer.
