1. Luxemburg carbide tipped 2. Much more specification for you choose 3. Finishing cutting without chip and without burning. Plastic boxes.

1, the classification: drilling, exploration, oil, drill, and drilling accessories 2, the product name: 215.9 mm 8 1/2 inches £¬rubber sealing disc bit three 3, product introduction: H series bit for O form rubber sealing sliding bearing drill bit, in a routine use can withstand high speed drilling of pressure. 4, its main structure features: 1) using high strength and high toughness cemented carbide gear, improve the shock resistance ability of teeth, reduce the broken teeth rate 2) the optimization of the tooth row number, gear, toothy height and unique alloy tooth shape, give full play to the drill bit cutting ability and the cutting speed 3) the card spring lock, able to bear high disc drilling pressure 4) die hole with gold, and improve the welding minus integration of the bearing capacity of bite 5) using high saturated acrylonitrile-butadiene rubber sealing ring, optimization of o-type seal compression quantity and improve the reliability of the bearing seal 6) can limit the pressure difference and prevent drilling fluid into the lubrication system of the rubber oil storage sac, for bearing system provides good lubrication, and to ensure that "O" type sealing ring, improve the normal work bit working life 7) with 250 ¡æ high temperature resistance, low wear new, improving the drill bit sealing grease lubrication system high temperature resistant ability. According to the customer request.

Drill bits: 1)Certified by ISO9001&API 2))Used for water well, oil field 3)IADC:114-117,127,437,517,617,637 200MM*200MM*250mm
