The abrasive layer of diamond glass drill bits usually uses high-quality diamond particles, which are carefully selected and tightly combined to ensure excellent cutting performance and durability. The thickness of this diamond abrasive layer is typically 1 mm, while the overall height of the drill bit is 10 mm. This thin-walled design allows the drill bit to easily penetrate glass, while reducing wear on the drill bit and extending its service life.
