Tungsten carbide acicular drill is new technologies develop by our drilling engineering since our reform. When used in hard rock, the acicular drill is more superior to steel, which with high efficiency, good quality, low cost, low consumption of steel and other advantages. Acicular drills and diamond drilling supporting the implementation of tiered drilling, for promote small-caliber diamond drilling has important significance. Tungsten carbide acicular drill advantagesthe advantages of acicular drill include the following:1high efficiencywith self grind edge features, acicular drill take many rocks free surfaces, it is more conducive to breaking rock. Drilling in the grade of 6 to 7 rock, the efficiency is one times than conventional carbide.2high qualityaperture are rules and uniformly, drilling with small curvature. The take rate of limestone core could reach to 80%90% in the grade of 6 to 7.3long lifetime56mm acicular drill in seven limestone formation drilling, average bit life is 9.92m, it is three to five times than normal carbide drill, and the highest life is 23.98m.4less consumption of steelacicular drill is less 60% than conventional carbide in per meter drilling and abrasive costs. 5reused bit materiallow cost in the drill manufacture, a drill bit can be reused 2 to 3 times.6easy to operatesmall labor intensity, inner hole is cleaning, security is relatively good.
