Diamond Drill Bit For Tempered Glass

This is a professional diamond drill bit used for drilling holes in glass.Tempered glass/Reinforced glass belongs to safety glass. Tempered glass is actually a type of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external forces, it first offsets the surface stress, thereby improving its load-bearing capacity, enhancing its own wind pressure resistance, cold and heat resistance, impact resistance, etc. Pay attention to distinguishing it from fiberglass.

Our company provides users with various specifications of diamond drill bits for drilling glass joints. Other specifications can be customized according to user needs.

Water needs to be added for use

Check if tempered glass can be perforated. Tempered glass with poor quality cannot be perforated, and tempered glass that is too thin cannot be perforated. So, only high-quality tempered glass and tempered glass with a certain thickness can be drilled.
Rules for opening holes in tempered glass:
① Only tempered glass with a width greater than 8 times the thickness can be drilled
② Tempered glass with a thickness not exceeding 12mm should have a spacing of no less than 1.5 times the thickness of the glass from the edge of the hole to the edge of the glass; Tempered glass with a thickness exceeding 12mm should have a spacing of no less than the glass thickness from the hole edge to the glass edge
③ The diameter of the circular hole on tempered glass should be 1.6mm larger than the thickness of the glass; The diameter of a circular hole should be less than 1/3 of its width; The radius of the rounded corner of the irregular hole on the glass panel should be greater than the thickness of the glass
④ When opening a hole at an angle of no less than 90o, the distance from the hole edge to the toe should be greater than 6.5 times the thickness of the glass
⑥ The concave part should be selected with a rounded radius not less than the thickness of the glass
