Definitions
- This invention relates to an impregnated diamond drilling bit for attachment to the end of a drill string.
- the invention is particularly, but not exclusively, applicable to coring crowns which cut rock cores.
- Known impregnated coring crowns consist of a head (which performs the actual drilling) in the form of a matrix, prepared by powder metallurgical methods, in which the diamond particles are distributed as homogeneously as possible.
- the matrix consists of a bronze.
- the matrix consists of one of, or a mixture of, tungsten, tungsten carbide, nickel and many other metals and refractory carbides infiltrated with a nickel bronze.
- the matrix depending on its composition may be prepared by either hot-pressing or by infiltration.
- an impregnated drilling bit which has a working face, the working face having diamond particles embedded in a matrix and the matrix including particles of a scouring agent selected from the group consisting of alumina, boron carbide and silicon carbide, the scouring agent particles being not larger than the diamond particles and preferably between one quarter and two thirds of the size of the diamond particles.
- the scouring agent particles are brittle and hard and have a limited ability to bond to the matrix.
- the scouring agent particles are preferably silicon carbide particles which are between one half and two thirds of the size of the diamond particles.
- the silicon carbide particles are present in sufficient quantities that when they tear loose they will scour away matrix from around the diamond particles.
- the matrix and the scouring agent In choosing the matrix and the scouring agent, one must firstly ensure that the diamond particles will be firmly held. Secondly the scouring agent particles must break away in time to erode the matrix to keep the bit open, but not so soon as to deprive the working diamond particles of the support of the matrix.
