Replaceable sleeve stabilizer consists of mandrel and sleeve. The function is the same as spiral integral blade stabilizer. It can be suitable for different hole size by changing different size sleeve. It can also increase the stabilizer service life by changing sleeve. The sleeve is threaded on mandrel, so the connection between the sleeve and the mandrel are more reliable, and it is more convenient to replace and assemble.
