What is a Tricone Bit?
A tricone bit is a drill bit with a head that is divided into three
main rotating cones, each with its own row of cutting teeth, that
crush the rock face they are rolled over. Tricone Bits were
developed in 1933 by the Sharp-Hughes Tool Company and offered a
big advantage over the existing two cone Roller Bit offering
improved durability and rate of penetration of the rock.
The Tricone Bit is the most versatile drill bit on the market. It
is the go-to drill bit in most styles of drilling. Whether you are
drilling a water well or an oil well, Roschen group limited has the
Tricone Drill Bit for you.
The Advantages of Using a Tricone over Other Drill Bits:
1. There is a Tricone suitable for any rock formation
2. Tricone bit is versatile and can handle changing formations
3. Tricones are reasonably priced, long lasting and have an
efficient drilling rate

Cost of a Tricone Bit:
The cost of a good drill bit varies from about 1-5% of the total
cost, however, the drill bit will affect up to 75% of your total
cost.
1. Reducing the number of times you trip
2. Increased rate of penetration when drilling means more holes
faster
3. Straighter holes and longer bit life
4. Saves you time and money
Depending on your application, Roschen group limited can provide
you with new, re-run or 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.
