Secoroc COP 64 Gold down-the-hole hammer used Tricone 9 7/8 inch Tricone Rock bits for Australia Mining Blast Hole Drilling

ROSCHEN is rock drilling tools manufacturer, As for rotary drilling tools, we have complete product line of tricone bit which are available in steel tooth and tungsten carbide insert, size from 3 3/8''(85.7mm) to 26''(660.4mm) for use in all formations, with any bearing/seal type, and a wide range of additional custom features.

The TriCone Bit is the most versatile drill bit on the market. It is the go to drill bit in most styles of drilling. ROSCHEN Tools always has the right Tri Cone Drill Bit for you Whether you are drilling a water well or an oil well.

Depending on your application, we can provide you with new, premium oil field quality Tricone bits. The difference between a premium oil field Tricone bit and non-premium oil well quality Tricone is that the roller cones have high end sealed bearings; extremely high quality tungsten carbide and diamond gauge protection throughout the drill bit as well as skirt tail hard facing and optimized hydraulics. These roller cone drill bits are designed to go to extreme depths in extreme conditions and in situations where they cannot fail.

Tricone drill bits include Steel Tooth (also referred to as milled tooth) bits and Tungsten Carbide Insert (TCI) bits, TCI bits are much more durable than Steel Tooth ones, but carry a higher cost to manufacture. Both these two groups of Tricone Bits are available with:
 

(1) Open Bearing or Sealed Bearing

(2) Roller Bearing or Friction Bearing (Journal Bearing)

(3) Gage Protected or Non-Gage Protected, etc
 

Features:

1. The tricone roller bit working life is according the drilling formation and the drilling rig.

2. Rock formation: Very soft with low compressive strength and high drill ability, such as shale, clay, sandstone and conglomerate, etc.

3. Journal bearing. Hard faced bearing surface. Inner hole of cone is silver-plated. The load capacity and seizure resistance of the bearing is greatly improved.

4. O ring seal is made of the more wear resistant and high saturated buna-N with the increased seal section and precisely designed scaling flange in the cone sealing area has increased the reliability of the seal.

5. All rubber compensator is used which can limit pressure differential and prevent drilling fluid from entering the lubrication system and this provides the bearing system with good assurance of lubrication.

6. High wear resistance and excellent cutting ability of the insert bit are given full play by using carbide compacts of high strength and high toughness in combination with optimized compact numbers and rows, the exposure height and special shaped compacts. For steel booth bit, the tooth surface is hard faced with new type of wear resistant material and thus has extended working life of the cutting structure while still maintaining high ROP.
