Features of this metal-seal 537 tricone drill bit
Offset crested scoop compacts in innerrow, wedge compacts in outer row andinequable spaced compactsarrangement. It is suitable for mediumsoft with low compressive strengthand harder abrasive stringers, such as hard shale, hard gypsolyte, softimestone,sandstone and dolomitewith stringers, etc.
Difference between rubber-seal tricone drill bit and metal-seal tricone bit
Tri-cone drill bits with metal-sealed bearing structure are broadly used in very tough or complicated formations. Compared with rubber-sealed structure, a metal-sealed tricone bit bears heavier W.O.B. and survives longer in different conditions. On the other hand, better performance means higher price. Metal-sealed tri-cone drill bits are generally 30% more expensive than rubber-sealed ones. This is an approximate price gap, which really depends on factories and drill bit size.
How to distinguish metal-seal ticone bit from rubber-seal tricone bit
From the appearance, it is really hard to differentiate the two types. Because the bearing struture is invisiable!
But we still could check the bottom printing to identity whether it is a metal-seal roller bit or a rubber-seal one. Check the figure 1. below.
“XM” means it is a metal-seal tricone bit. “M” mean “metal”.
“XA” means it is a rubber-seal one.
Of course, beside from the bottom, you can also check the model info from the outer package. But sometimes you can not remember which is its own package.

Other Q&A
Q: What are your products always available in stock, or those always need time to manufacture?
A: Typically, they are tri-cone bits. We stock from popular models directly from KINGDREAM factory, like 6”/6 ½”/8 ½”/9 1/2”/12 ¼” IADC537/617/637.
On the other hand, hole openers(reamers) always need to be customized. Because customers’ drill rigs vary so much, we need customize the thread types for them on the reamers. Especially for rock reamers, the customization not only comes from the thread type, but also from the IADC code and the distribution density of the roller cones. Lastly, sometimes we need design the reamers according to customer’s drilling plan, especially the design of centralizer size.
As for other products, it depends. Mud motor is more like to be available as there’s not so much customization. Kindly inquire from us if you want to check our stock status.
Q: What a brand is KINGDREAM?
A: KD is a subsidiary of SINOPEC, China’s state-owned oil company. It was and is ranked the 2st among the top 500 companies all over the world.
KINGDREAM is the top-tier company for drill bit design and manufacture. Including tricone drill bit (Roller drilling bit) and PDC (Polycrystalline Diamond Compact) bit and other drill bits.
Q: Do you have experience of global delivery?
A: Yes. From America to the middle east, from Africa to India, from Brazil to Australia, we are familiar with how to deliver satisfactory to all of you.
Q: Can you manufacture drilling bits or reamers or other tools for different brands of drill rigs?
A: We won’t say it’s 100%, but almost it is. We’ve configured tools for all the mainstream machines brands like Vermeer, Ditch Witch, Herrenknecht, XCMG, Goodeng…
