HXIN Vacuum Brazed (VB) diamond core drill and mill bits are professionally produced for dry or wet drilling, milling, beveling on all types of ceramic, especially porcelain, tile, granice, marble, stoneware, and other hard materials.
With the VB technology, HXIN VB Diamond bits can perform both wet and dry drilling milling beveling on hard porcelain and stones with higher efficiency and longer life.

The HXIN VB diamond core drill and mill bits with 5/8"-11 thread connection can be used directly on angle grinder.
The recommended RPM for using will be 11,000-14,000RPM.

Average life of drill bits ALWAYS depends on the type of material, its thickness and good cooling and use.

HXIN VB diamond core drill and mill bits can be used to drill and mill the necessary holes for water inlets, drains, light points, etc.

HXIN Vacuum Brazed (VB) diamond core drill and mill bits include 2 functions in 1 bit, you can drill the holes on the hard materials, and you can milling or beveling after the drilling directly without wasting the time of changing tools. Your time is valuable.

To extend the life of the bits, please follow the correct instructions for using the method.

1. Please do not use the hammer mode of the machine.
2.Before re-drilling milling beveling, we must make sure that the core drill and mill bit is properly installed on the machine, firmly and without any vibration.
3.The core drill and mill bit should be clean and free from any obstructions.
4.When you are drilling milling beveling, only light pressure is needed (in the horizontal direction. The pressure of the weight of the machine will be sufficient in the vertical direction.)
All the data is measured manually, so there will be a certain deviation. Please understand.
