Description
Diamond milling bits ( dimaond finger bits) are professionally manufactured for dry or wet enlarging or shaping holes on all types of ceramics, especially porcelain, tile, granite, marble, stoneware and other hard materials.
With VB technology, diamond milling bits can mill both wet and dry on hard porcelain and stone with higher efficiency and longer life.
NBB VB diamond milling bits with M14 thread connection can be used directly on the angle grinder.
Recommended RPM to use will be 11,000 to 14,000 RPM.
The average life of the milling bits ALWAYS depends on the type of material and correct use.
They are dedicated to be an auxiliary tool for diamond hole saws.
They are not diamond hole saws which are used to drill holes. They can not be used for drilling holes.
But they are recommended to be used after drilling a hole, especially if you need to enlarge or shape a hole.
They can be used to enlarge the hole, or shape a hole at the edge of the ceramic. They can also chamfer the hole and make it clean. With it, you will find a clean, precise and beautiful finish on the edge of holes.
It is very useful to improve the aesthetic grade for finishing the edges of exposed holes.
It is highly recommended for use it, if you are going to drill a hole on a standard or large format tile, ceramic or stone. It can help much on reducing the risk of cracking when the tile is over stress.
To make the milling cutters last longer life, Please follow up the correct instruction of using method.
1. Do not use hammer mode of the machine.
2. Before making a new milling, we must make sure that the drill is installed in the machine correctly, firmly and without vibration.
3. The drill must be clean and free of any obstruction.
All data is measured manually, so there will be a certain deviation. Please understand.
