Claims
- 1. A method for applying cutting elements to a tool for cutting metal in a well bore, said method comprising:providing a cutting tool; forming a plurality of cutting elements from a uniform material harder than a piece of metal to be cut, with each said cutting element being formed of a plurality of cutting faces entirely covering the outside periphery of said cutting element, with each said face being shaped to turn a metal chip cut from a piece of metal back toward the piece of metal being cut to break the chip off at a short length; and bonding a pattern of said plurality of cutting elements to said cutting tool; wherein corrugations are formed as parallel grooves and ridges in at least one said face of at least one said cutting element.
- 2. A method for applying cutting elements to a cutting tool, as recited in claim 1, further comprising forming a concave contour in at least one said face of at least one said cutting element.
- 3. A method for applying cutting elements to a cutting tool, as recited in claim 1, further comprising forming at least one chip breaking surface irregularity in at least one said face of at least one said cutting element.
- 4. A cutting element for application to a tool for cutting metal in a well bore, said cutting element being formed with a plurality of cutting faces entirely covering the outside periphery of said cutting element, with each said face being shaped to turn a metal chip cut from a piece of metal back toward the piece of metal being cut to break the chip off at a short length, and with said cutting clement being formed of a uniform material harder than the piece of metal being cut, wherein at least one said face of said cutting element is corrugated with parallel grooves and ridges.
- 5. A cutting element as recited in claim 4, wherein at least one said face of said cutting element is concave.
- 6. A cutting element as recited in claim 4, further comprising at least one chip breaking surface irregularity formed in at least one said face of said cutting element.
