Item Name: 9mm Diamond Core Sintered Threaded Drill Bits for Glass SKU: DB-T-8 Description: This is a sintered, threaded 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 lifespan and maintains cutting performance as the tool wears. The drill is hollow-core so water can be fed through the center during use, helping control heat, clear swarf, and protect both the bit and the glass while drilling. How it is used: This bit is used in coldworking when you need clean, controlled holes in glass. Because it is a sintered core drill, it must be run with a continuous water feed moving through the center of the drill. That water flow is critical to prevent overheating, reduce chipping risk, and avoid damaging the drill and your work. The threaded shank is intended to mount to compatible threaded arbors or holders. Dimensions: 9mm diameter
