Carbide bit: a drill used in core drilling. The cylindrical steel bit is named after the carbide cutting tool with tungsten carbide. The shape of cemented carbide cutting tools, the number of them arranged on the drill bit, the arrangement and the welding angle are called the bottom, the inner edge and the outer edge, so as to ensure the clearance between the water and the powder. The upper part of the drill body is threaded connection tube, a drill bit body are arranged at the side part of the sink, the bottom surface is provided with a nozzle lip. Both the water tank and the water inlet ensure the circulation of the washing fluid, so as to eliminate the influence of the rock powder and the cooling bit. When drilling into the clay and shale formations, the ribs are welded to the inner and outer sides of the hard alloy drill bit in order to increase the gap, called the rib bit. Self drilling bits with needle like carbide can be used in hard formations with high abrasive properties. Rock drillability is a grade II VII formation general hard alloy drilling; acicular carbide drill drilling a rock grade VI viii.

Stainless steel is characterized by high toughness and easy sticking. Therefore, the drill hardness is required to be high, the surface finish is better, the drill bit angle is larger than the ordinary bit (130--135 degrees). Cool down at the same time. And the feed amount is greater than 0.15mm, so as not to cut the cold work hardening layer as much as possible. The cutting speed is as low as possible to reduce the cutting temperature. The cutting fluid is concentrated with emulsions. Commonly used processing stainless steel drill bit: high cobalt drill (M35 drill, M42 drill), in which the M42 bit is the best price performance. In addition, carbide drills can be used, but the price is higher.

Drilling stainless steel materials, there are two main domestic products: high-speed steel bit, carbide drill. Carbide hollow drill is of high toughness and good wear resistance. It is recommended that you use this material. The price depends on the specifications you need.
