CRL AG Series 7/8 in Plated Diamond Drill Bit for Glass & Tile

• Unique aggressive sawtooth profile for faster cutting
• Our most durable style drill — machined from solid steel
• Diameters from 1/8" to 4-1/2" (ideal for glass and glazing)

The special sawtooth design of CRL Amazing Glazing Plated Diamond Drills (SKU AG78) reduces contact area for improved grinding action and increased coolant penetration. These plated diamond glass drill bits are ideal for portable tripod and cup-style drilling machines and for drilling glass, tile, and ceramics with coolant. Use with DTC80 Diamond Tool Coolant and submerge in a retaining ring for best results. Although plated, these diamond drills may be sharpened one time with a CRL Sharpening Stone after they are fully worn to expose remaining diamonds and extend usable life.


NOTE: Always wear proper safety gear, including eye protection, when drilling glass. Work should be performed on a flat, horizontal surface. A Cat. No. GF1 Ground Fault Circuit Interrupt Device is recommended when using any electric tool with water or coolant. Failure to follow these precautions can result in operator injury.


Product Warning

NEVER perform freehand drilling. Hand drills require a stabilization base such as our GDB1 & GDB2 Glass Drilling Bases. Extreme care should be used — using these drills in any manner other than specified may damage the bit and void the warranty.
