Product Description

IMPREGNATED CORE BITS

NWL HWL PWL Impregnated diamond bit


Impregnated Core Bits are commonly used to perform geotechnical coring, gas content coring, and material sample coring and mineral exploration.

                
Impregnated Core Drill Bit produces a bit where the matrix, under given conditions, erodes at a rate where the active diamonds become blunt and in the process releases a fresh sharp diamond.  The matrix is a critical factor in Impregnated Drill Bit as it must have the capacity to retain the diamonds for as long as they continue to cut, and then allow the blunt diamonds to "strip" but resist the drilling forces and not to allow the sharp diamonds to be "pulled" prior to becoming blunt.
