The shank design will be selected to fit your equipment. A full range of drill bit designs is available to fit each machine while meeting the requirements for:

• Quick startup
• Accurate hole size
• Hole quality
• Spindle speed
• Feed rate
• Coolant type
• Tool life

Choose the right drill bit to match the driller machine, and make sure meets the requirement of glass hole size and thickness.

2. Clearance of drill bit

Clear drill bit with sponge including drill position part and surface;

3. Installation of drill bit:

Install both the bottom and top drill bits and check the radial runout less than 0.05mm;

4. Debugging of drill bit

Normally start up with 50%-60% of feed rate, after drilling 20-30 holes, check the hole quality, if no defect, speed up to 70%-80% gradually.
