Specification Brand : CEGBREU BulletPoint1 : Material: Our Oilfield OD Measure Gauge made of high quality stainless steel, it will not rust even in the extreme weather conditions of the oil field, unlike electronic products that can malfunction at low temperatures. BulletPoint2 : Double Scale: Our gauge can be read with imperial & metric readings for easy and intuitive use and is accurate to within 0.5 mm, allowing for precise measurement of bit and downhole tool wear before and after the trip. BulletPoint3 : Easy to use: Put the bit or stabilizer into the gauge, then contract the gauge until it is tangent to the face of the drill bit, then the value of the movable scale is the outer diameter of the drill bit. BulletPoint4 : Maintenance: After use, wipe off surface drilling fluid and apply a small amount of lubricant between each gauge, repeating several times so that the lubricant is evenly applied to each gauge and each gauge remains flexible.
