bit 8 1/2" tricone bits for mining machines

bit 8 1/2" IADC537G tricone bits for mining machine

Feature:

• There is a tri cone suitable for any rockformation

• Tri cone bits are versatile and can handlechanging formations

• Tri cones Are reasonably priced with longlife and good rate of drilling

Depending on yourapplication we can provide you with new, re-run or premium oil field qualitytricone bits. The difference between a premium oil field tricone bit andnon-premium oil well quality tricone is that the roller cones have high endsealed bearings; extremely high quality tungsten carbide and offer diamond gaugeprotection throughout the drill bit as well as skirt tail hard facing andoptimized hydraulics. These roller cone drill bits are designed to go to extremedepths in extreme conditions and in situations where they cannotfail.

When Ordering a bit theIADC bit classification system is a very useful tool and allows us to specify abit that out preform your expectations.

Our TCI tricones bitsRange in size from 3.875" (88.9mm) to 28" (711.2mm)
Our Mill tooth tri conedrill bits range in size from 5" (127mm to 32" (812.8mm)

• 4 character code, first 3 characters arenumbers, the last is a letter

• 1st number is the series. 1 to 3 representa milled tooth tri cones, 4 – 8 represent TCI tri cones. The higher the seriesnumber the harder more abrasive the rock formation is.

• 2nd number is the relative degree ofhardness within a series. The number ranges from 1 – 4, the higher the numberthe harder the formation

• 3rd number represents bearing design andgauge protection.

1. Open bearing

2. Roller bearing air cooled

3. Open bearing gauge protected

4. Sealed roller bearing

5. Sealed roller bearing gauge protected

6. Sealed friction bearing
