2.The normal tapered butten bit is 7 degree, if the user require other taperer butten bit, we can design it for you.
3.If the hole depth is deeper than 2.5m, please use the set of rods, firstly,using shorter drill rods, then the loner rods, which can improve the life of rods; For example,if you want to open a 5m depth hole, you should take 1m,2m,3m,5m, totally four pieces rods; If you want to open a 6m depth hole, you should take 1m,2m,3.5m,5m,6m, totally five pieces rods.
4.Take attention to the stability when drilling, reduce blow rate suitably,avoid to work under the bending condition.
According to the working condition, if the rod is easily to stuck to the stratum, cross bit is the better choice or just need to adjust the air volume of drilling rig to make sure that the drilling row power is normal.
