Usage: Core Drill, Prospecting, Exploration Material: Diamond Type: Core Drilling Rig Length: 6-24mm Standard: ISO SGS Customized: Customized Matrix Height: 6-14mm Condition: New Standard: Boart Longyear Standard Quality: High Quality Trademark: csmiracleland Transport Package: Each Bit Is Independently Packed in a Small Carton Specification: DCDMA, CDDA, ISO Origin: Changsha, Hunan, China HS Code: 8207191000 Product Description 1. Full Q series and T series drilling sizes (B,N,H,P);2. Various waterways design;3. Long bit life and good performance;4. Cost effictive.Our impregnated bits are manufactured to give optimum penetration rates and bit life, which is required to keep the cost of diamond drilling to a minimum.Crown Height:We could offers crown impreg depths of 8mm, 10mm, 12mm and 14mm .The taller crown heights provide improved bit stability and reduced vibrations, enhancing bit life and performance.Waterways:Various waterways are available for diamond impregnated bits. Differing waterways allow for better flushing in various ground conditions and drilling systems.The choice of the diamond bit crown shape:W ProfileSuitable for drilling hard dense formations with high penetration rate.Semi-Round ProfileImpregnated bits with this profile are recommended for use in highly fractured formations with good drilling stability. Surface set bits of this style have a long bit life and the matrix is not easy to be damaged.Flat ProfileIt's suitable for various rocks, often used in impregnated casing bits, casing shoes as well as the bits with very hard matrices(e.g. F1, F2).Cross ProfileIt's especially designed for ultra-hard formations, such as granite (hardness 8-9), ganister, quartzite, siliceous limestone, chert, etc.Multi-Step ProfileMulti-Step type impregnated bit are suitable for soft to medium hard formations and alternating hard-soft formations. With very good drilling stability, it makes the borehole not liable to deflection and the penetration fast. This profile is also often adopted in thick-kerf surface set core bits, with good drilling stability and fast penetration.Shaped Gear ProfileIt's suitable for competent formations, and can expand the flushing ways and improve the penetration rate.Face DischargeIt's suitable for sedimentary and metamorphic formations, or the formations including with lots of mineral powders, this design can protect the core from flushing and improve the getting effciency of core samples.Dimensions of Core Bits:A-Gauge Core BitsSizeOutside diameterInside
