The DTH drill is a one-piece DTH drill, the DTH drill without activity components, structure is simple, has high strength, high wear resistance and impact resistance ability, field application proves that the DTH drill steel body PDC drilling in soft - hard formation, the over speed and penetration, long service life, stable work, less downhole accident, well bore as well as good quality. Application is now in the market more kind of DTH drill bits.
Diamond PDC composite DTH drill steel body with long time not only, also can be repeated use, can help clients save a lot of money. DTH drilling quality, length of service life, and the selection of raw materials has Tapered Rock Bit a direct relationship. , of course, the influencing factors of DTH drill PDC products and there are many, such as the use of the customer, what kind of rock in quality, many factors, has an effect on the service life of the product. If used on a hard rock mine, damaged the compact will be a little big, so to the requirement of diamond compact raw material is higher.
PDC diamond DTH drill is one of the important tools for mining work now. In many parts of the mining work now can use this kind of product. PDC diamond rock fragmentation principle of DTH bit decided its efficiency. PDC DTH drill the rock fragmentation mechanism of diamond have? Serious analysis of the related content, to improve the work efficiency.
Specifications of the hollow DTH bit normally done with high-speed tool steel, the range of 16 - phi phi is roughly 50. We use the high speed tool steel with M2, M35 and three kinds of high performance, to adapt to the different cutting conditions, respectively. Phi is more than 50 we advocate to do with hard alloy material, cemented carbide with welded and machine clamp type two kinds, we suggest that the large size of the hollow DTH drill using carbide indexable insert machine clip, this is beneficial to reduce the cost of production, save raw materials, improve work efficiency, give full play to the superior carbide blade cutting performance.
Hollow DTH drilling has many unique advantages, especially in the depth of borehole size number long time, the use of its superior performance can be fully played out, the work efficiency greatly, it is common twist DTH drilling mining drill bit and cutting tools can't instead of commonly, large size of cemented carbide indexable insert machine clip type hollow DTH drill will also be in power generation, transmission, boiler, and play a large role in the construction of national defense.
