CRL AG Series 7/16" 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" (suitable for glass and glazing applications)

The special sawtooth design of CRL Amazing Glazing Plated Diamond Drills (SKU: AG716) reduces contact area for improved grinding action and increased coolant penetration. Ideal for portable tripod and cup-style drilling machines, these plated diamond glass drill bits are machined from solid steel for superior durability. For best results use with DTC80 Diamond Tool Coolant and submerge the bit in a retaining ring. Plated construction allows one-time resharpening with a CRL Sharpening Stone when fully worn to expose remaining diamonds and extend service life.


NOTE: Always wear proper safety gear, including eye protection, when drilling glass. Perform work on a flat, horizontal surface. Use a Cat. No. GF1 Ground Fault Circuit Interrupt Device when operating electric tools 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 the GDB1 or GDB2 Glass Drilling Bases. Using these drills other than as specified may damage the bit and void the warranty.
