Product Description

Type of Bit:

Head Diameter:	40 mm -200 mm (D)
Bit Type:	Button Bit, Cross Bit
Button Type:	Semispherical Button, Ballistic Button, Conical Button
Thread:	R25, R32, R38, T38, T45, T51(T)
Bit Body:	Standard Skirt, Retrac Skirt
Bit Face:	Flat Face, Concave Face, Convex Face, Drop-Center Face
Material:	High quality tungsten carbide

The selection of Bit Face Type:

Drop center face bit:	It has high penetration rates in soft to medium hard and fissured rock formation, and has better hole deviation control.
Concave face bit:	It’s suitable for medium hard and similar rock formations, it has good hole deviation control and good flushing capacity.
Convex face bit:	It has high penetration rates in soft to medium-hard rock formation. It has the best performance of resistance to steel wash, and reduce the load and wear on the gauge buttons, but it has poor hole deviation control.
Flat face bits:	It’s suitable for hard to very hard and abrasive rock formations.

The selection of Bit skirt:

Standard skirt:	This design is suitable for most of rock formations.
Retrac skirt:	This type design can get better hole deviation control while drilling, it can get bit back easily while the bit is jammed during drilling.

Q: Why does the precision casting factory not usually make iron castings?: Jiangyin Lin Xing stainless steel (precision manufacturing) Co., Ltd. to provide professional precision casting

Q: The casting defects of pores, trachoma how to repair?: If the repair after the high temperature resistance, choose LT737 high temperature repair agent.

Q: Domestic large steel castings factory which is better, recommend!: Do the casting manufacturer of large steel castings, Hunan Jinsha heavy industry science and technology limited company, heard that their professional only more than 1 tons of steel castings, anyway, 150T just big, the company won a lot of foundry industry patents should be good. At least spend money on research and development, then the quality should be all right.

Q: Casting parts by shot blasting, spray painting, baking after the formation of very small rust spots, how to solve ah?: The first process is very important. Shot blasting must be thorough. The solution is to wipe the surface of the paint with a release. Re shot

Q: What is the difference between forging parts and casting parts?: No, it's called die castingDifference: the die casting parts are simple in structure and large in batch sizeCasting: the use of a wide range of structures without restrictions

Q: In theory, which is more expensive, forging parts or casting parts?: Compared with the price, the product with the same simple structure eliminates the material factorsThe forgings must be more expensive

Q: What is the reason for 304 stainless steel precision casting parts to be changed?: 304 stainless steel is easier to change than ordinary steel. Because the 304 heat conductivity is lower than that of the low doped steel, the temperature is even more uneven, and 20% of the non ferrous elements also make the distribution of internal and external elements more uneven, hard and soft inside. Each of these two produces greater internal stresses, resulting in a variant.

Q: After reaming, the roughness can reach several levels, that is to say, the sample.Casting parts in rocker arm drilling, reaming, roughness, block. After reaming, the roughness can reach several levels, that is to say, the sample.: The finish of reaming depends on the material and the sharpness of the reamer, as well as the speed and speed of the top and bottom. Marine machine tool

Q: What is the difference between casting and stamping parts?: Cold stamping is generally no longer done by cutting, or only a small amount of cutting is required. The precision and surface state of hot stamping parts are lower than those of cold stamping parts, but they are better than those of castings and forgings, and the amount of cutting is less.Stamping is mainly based on process classification, can be divided into separation process and forming process two major categories.

Q: Younger brother is to do casting valve, precision casting parts, the valve internal sand serious, but the appearance is very standard, this is why, for God answers, thank you!: Valve sand core mold drying is not in place, excessive water content
