There is no doubt that diamond hole openers play an important role in our daily lives. But what should you consider when buying a diamond hole drill?
First, you need to determine what material you plan to cut the hole in. If it is made of metal, a high-speed drill is required; but if it is made of fragile materials such as glass and marble, a diamond hole opener should be used; otherwise, the material may break easily. At the same time, it is necessary to make sure that the material of the base material cannot be harder than the hole opener. It is recommended to use a bench drill for hole openers above 10mm. It is recommended to advance at low speed for holes above 50mm. For holes above 100mm, it is recommended to add coolant at low speed.
The second thing to consider is that you should choose different diameter drill bits based on your intended diameter. Choosing the right drill bit is crucial. The choice of drill bit is determined by the thickness of the tile.
To minimize the possibility of surface cracks, it is important to moisten the tile surface with water before drilling. In addition, be careful not to use too much force when drilling to avoid drilling through the entire tile. This reduces heat conduction and reduces surface cracks caused by the large amount of heat generated during drilling.
Use a dust cloth to make sure all dust is removed from the area. Install the hole opener correctly, such as whether the center of the fixed plane of the drill bit is aligned with the mounting screws of the drill. When tightening the screws, the gap must be completely eliminated. Misaligned installation is strictly prohibited. In addition, the correct selection of rotation speed and control of feed speed require slow feeding. If the operator feeds the knife with great force, the hole opener will not be durable and may be broken in a few strokes. Otherwise, if we follow our correct operating methods, it will last a lot longer.
