“Hi Feng, The core lifters from Wuxi have been performing well. We have done some comparisons to them and Boart Longyear and they are quite similar. We prefer the core lifters with the finer teeth as shown on the right.”
Mr. Cristulo Maturan& Mr. Randie Robantes:
Hi Sir Eric,
Good day!
With your continuous support and for providing our orders on time.
We are glad to announce that we have achieved 1000 meters using below bit.
