7mm Diamond Core Sintered Straight Drill Bits for Glass

Description:
The 7mm Diamond Core Sintered Straight Drill Bit is a sintered core drill designed specifically for drilling glass, with diamond content throughout the tip rather than only on the surface. This sintered construction is intended to improve drill lifespan and increase drilling speed and efficiency compared with brazed or plated drills. Because it is a core drill, it requires continuous water feed moving through the center of the bit to protect both the drill and the work during use.
How it is used:
This bit is used in glass coldworking when you need to drill clean, controlled holes with a core-style cut. In practice, you run the drill with a continuous water feed through the center to keep the cutting zone cool, flush debris, and prevent heat damage to the glass and premature wear to the bit. The sintered diamond structure supports steady, efficient drilling for repeated hole-making in studio fabrication and production work.
