• The glass hole cutter is made of iron alloy, which is very sturdy. At the same time, the surface is nickel plated, which has good rust resistance, corrosion resistance and prolonged service life
• The diamond drill bits with thicker diamond coating make the edge of the groove sharper, which can achieve smooth and high precision cutting. Large chip holes on the side can remove waste, ensuring smooth and accurate punching
