CRL 4" Plated Diamond Drill Bit for Glass & Glazing

• Unique, aggressive sawtooth profile for faster glass cutting
• Our most durable plated drill — machined from solid steel
• Diameters from 1/8" to 4-1/2" (3.2 to 114.3 mm)

The special sawtooth design of CRL Amazing Glazing Plated Diamond Drills (SKU: AG4) reduces contact area for improved grinding action and deeper coolant penetration. Ideal plated diamond glass drill bits for portable tripod and cup-style machines, these glazing drills are machined from solid steel for maximum durability. Use with DTC80 Diamond Tool Coolant and submerge in a retaining ring for best glass drilling results. Although plated, these drills can be sharpened once with a CRL Sharpening Stone after they are 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 any type of freehand drilling. Hand drills require a stabilization base such as our GDB1 & GDB2 Glass Drilling Bases. Extreme care is required — misuse may damage the bit and void the warranty.
