Item Name:
7mm Diamond Core Sintered Threaded Drill Bits for Glass
SKU:
DB-T-7/8
Description:
This is a sintered diamond core drill bit designed specifically for drilling glass. Unlike brazed or plated diamond drills, a sintered core drill has diamond content throughout the working tip, which improves both lifespan and drilling efficiency as the bit wears. The bit is built as a hollow core drill so water can be fed through the center during use to cool the cutting surface and flush debris.
How it is used:
This bit is used in coldworking and fabrication when you need to drill a clean, controlled hole in glass. Because it is a sintered core drill, it must be run with a continuous water feed through the center of the drill while drilling. The water prevents overheating that can damage the drill and helps protect the glass from thermal stress while also carrying glass slurry out of the cut.
