Q1: What is a diamond core bit?
A: Diamond Core Drill bit is to weld the metal-bonded segments including a qualitied grade of diamond grains to the reforced steel tube. As an accessory, it needs to be used with core drill machine , in handheld type or stand type. By high speed rotation of the drill head, the hard segments will drill through concrete block/ pavements/ wall/ piles etc., to finish all kinds of coring work for construction.We also have other model of diamond core drill bit for your choice.
Q2: Do you need water for core drilling ?
A: For general conditions, the water resource is required for coring job. First of all, the water can help cool down the core bits for better performance and longer durablity in case of overheat; secondly, the water can bring out the dust generated by coring job for smooth work from getting stuck. Third of all, if coring without water, there shall be dust containment to collect the harmful dust from concrete. We also have the dry type diamond core drill bit for your job.
