1.Diamond Core Drill,perforation of hard and brittle non-metallic materials such as stone and ceramics.
2.Wall holes for installation of water, electricity, gas, air conditioning and pipes in buildings.
3.Drilling, cutting and coring of basic engineering such as expressway, Airport runway, bridge and tunnel
1. Water drills shake when drilling holes. Why do they always run away?
Because the diameter of the drill is relatively thick, please form an inclined angle of about 60 degrees between the front end of the drill and the wall when using it, and then gradually straighten the drill in the time of drilling about 5 mm, and then normal drilling operation!
2. Water drill drill bit bought back for the first time to use, which has a well-equipped drill bit is a bit shaky what is the reason, is the quality problem?
Because the bit is slightly irregular after opening. This situation only needs 10 minutes of normal drilling to run in, so it does not affect the use!
No need to open the edge. The cutting part of the water drill bit is diamond. During the drilling process, diamond particles play a cutting role. The hardness of the bonding agent (usually copper alloy) is less than that of diamond and is constantly worn, which makes new diamond particles continuously exposed for drilling and cutting, so no cutting edge is needed.
4. What should we do if the drill bit of the water drill is stuck?
Basically there is no good way. First remove the bit with the big wrench of the disassembly and assembly bit, then rotate slowly in the opposite direction with the wrench. If it can't rotate, you can tap the bit gently with the small hammer. Be careful not to use too much force when tapping. If it's too strong, it's easy to knock the bit out of shape and then it won't work next time.
