water well diamond drilling bits

 

Adapt to 1, Pdc bit rock coefficient

Apply to hard-hard stratum in the drilling. Apply to lithologic wide, long service life, high efficiency; Different types of drilling, lip shape face, tire body formula bit in all types of strata always maintain excellent performance, let users get the best comprehensive benefits.
Type (both can match for the expansion)-natural diamond drill set table; Natural diamond impregnated bits; Synthetic diamond impregnated bits.
Specifications (core and not taking core)-Φ 28-Φ 153

 

 

 

2, PDC bit (PDC)
Used for soft-hard strata in the drilling. With the new type cutting superhard materials, bits long life. Cutting the free surface, into more high efficiency; According to the characteristics of strata, matching different level structure, drill the adaptability is strong; Pure drill time efficiency is high, effectively reduce the labor intensity, comprehensive benefit of good.
Specifications-to take core: Φ 75/53, 94/69, 113/88, Φ Φ Φ 133/108, 153/128 Φ; Don't take core: Φ 60, 75, 94, Φ Φ Φ 110, 113, 133, Φ Φ Φ 153, 190, 215 Φ Φ.
Type-to take core: a type, ladder type; Don't take core: arc pillar, ladder (type), 3 wing cone scraper type, concave 3 wing scraper type.

 

 

 

3, PDC (PDC) anchor the bit
Apply to the mine, transportation, water, and electricity anchor nets support into the department.
Half a piece of ordinary PDC bit is applicable to the 6 f the soft formation; The whole piece of ordinary PDC bit is applicable to f = 6-10 more integrated hard rock; The whole piece of high-quality goods PDC bit is applicable to f = 10-12 of relatively complete hard rock; Natural diamond drill is applicable to watch/f = 12 to 18 of relatively complete hard rock.
Φ 27, Φ specifications-28, 32, Φ Φ 36, Φ 42.
