IADC 437 Tungsten Carbide Tricone Drill Bit 8 1/2 Inch For Medium Hardness Rock Formation Drilling

IADC 437 Tungsten Carbide Tricone Drill bits 8 1/2 inch for Medium Hardness Rock Formation Drilling

Tricone bit, insert design, design of the bearing friction sealing protected OD, diameter 8 - 1/2 in, number of cones 3, type of connection API REG SHANK, size of the connection 4-1/2 IN, additional protection leg and cone, type of protection additional insert of CARBIDE tungsten, IADC code 437, nozzle does not include tip CENTRAL, standard of manufacture API 7-1 last edition

Reinforced tooth medium hard rock tricone bit

1) soft rock teeth apply for: low compressive strength of the soft formations, such as mudstone, gypsum, salt rock, soft shale, soft limestone

2) Medium Hardness Rocks Applies to soft to medium formations with low compressive strength such as medium soft shale, medium soft limestone, medium soft sandstone and medium formations with harder abrasive interbeds

3) hard rock teeth apply to: high compressive strength, hard and abrasive formations, such as hard shale, limestone, sandstone, dolomite, flint, etc.

Features:

1. The use of high strength and high toughness of cemented carbide teeth to improve the impact resistance of the teeth to reduce the teeth rate;
2. Optimize the design of the number of teeth, the number of teeth, exposed teeth and unique alloy tooth profile, give full play to the drill cutting capacity and cutting speed;
3. The use of retaining ring locking cone, can withstand high pressure;
4. Cone hole inlay welding alloy, improve the resistance of the bearing resistance;
5. The use of high saturated nitrile rubber O-ring, optimized seal compression to improve the reliability of the bearing seal;
6. The use of a rubber hose that limits the differential pressure and prevents the drilling fluid from entering the lubrication system provides a good lubrication for the bearing system and ensures that the "O" ring is working properly and improves the working life of the drill bit;
7. The use of resistance to 250 ℃ high temperature, low wear and tear of the new grease, improve the bit seal lubrication system high temperature resistance.

Product advantages:
The use of conventional speed can withstand higher drilling pressure.
