CRL AG312 3-1/2" AG Series Plated Diamond Drill

C.R. Laurence AG312 3-1/2" AG Series Plated Diamond Drill is engineered for exceptional performance and durability, making it an essential tool for glass drilling applications. Featuring a unique aggressive sawtooth profile, this drill reduces the contact area for improved grinding action and enhanced coolant penetration, ensuring efficient drilling even in portable tripod and cup style machines. Crafted from solid steel, the AG312 is C.R. Laurence's most durable drill, designed to withstand rigorous use. Available in diameters ranging from 1/8" to 4-1/2", it provides versatility for various projects. For optimal results, use it with DTC80 Diamond Tool Coolant and submerge it in a retaining ring. Once worn, the drill can be sharpened once with a CRL Sharpening Stone to expose remaining diamonds, extending its lifespan. Safety is paramount; always wear appropriate eye protection and work on a flat, horizontal surface. A stabilization base, such as the GDB1 or GDB2 Glass Drilling Bases, is recommended to avoid freehand drilling, which can damage the bit and void the warranty. With a wrist circumference of 3-1/2 inches and a reduced round shank diameter of 3/8 inches, the AG312 is a reliable choice for professionals demanding quality and efficiency in their tools.
