Product description:

Sealed Bearing Structure:Air cooling roller bearing package. Balls lock the conewhich reduces the probability of cone-dropping to minimum.

Main Type Available:Size: 5 7/8",6",6 1/2",7 1/2",7 7/8",8 1/2",9 1/2",9 5/8",9 7/8",12 1/4",14 3/4",17 1/2", etc.

IADC Code:1-- Series, 2-- Series, 3—Series

3. Non-Sealed Roller Bearing Steel Tooth Bit

Cutting Structure: The wear-resistance of teeth is enhanced with premium tungsten carbide hard facing on the tooth surfaces.

Bearing Structure: on-sealed roller bearing. Drilling fluid can enter the bearing directly for cooling; Balls lock the cone which reduces the probability of cone Cropping to minimum

Main Type Available: Size: 2 3/8",3",3 5/8:",3 7/8",4",4 1/2",4 5/8",4 3/4",6",6 1/2",7 1/2",7 7/8",8 1/2",9 1/2",9 5/8",9 7/8",10 5/8",12 1/4", 17 1/2",etc.

IADC Code:1-- Series,2-- Series,3-- Series
