Abstract
Singer PDC cutters of five different cone top diameters are designed and manufactured.On the basis of rock-breaking test with stinger PDC cutters, effects of significant factors on cutting forces are discussed, including cutting angle, cutter shape and rock hardness. The test results show that the stinger PDC cutters have the ability of drilling hard rock.The sharper the stinger PDC cutter is, the stronger the ability of drilling the formation will become.15°is an optimal front rake angle.
