C.R. Laurence STD312 3-1/2" Metal Tube Drill is a robust tool designed for precision glass drilling. Featuring one-piece construction, this drill offers exceptional rigidity and durability, making it a reliable choice for professionals in the glass industry. Known as the "Old Reliable" method for drilling glass, it utilizes a unique abrasive grain, such as CRL Silicon Carbide Grain, to achieve clean and accurate holes through rotational abrasion. The STD312 works effectively with a CRL Tripod Drill or similar drill machines, utilizing a 1/4" (6.4 mm) diameter shank that fits most drilling equipment. For optimal results, a coolant or water is mixed with the abrasive to create a slurry, carefully retained by a CRL Rubber Base Drilling Ring. This method ensures minimal breakage and chipping, allowing for a smooth drilling process. Safety is paramount when using this drill; always wear appropriate eye protection and perform work on a flat, horizontal surface. Additionally, a Ground Fault Circuit Interrupter is required when using electric tools with water or coolant to prevent potential injuries. The STD312 Metal Tube Drill is an economical solution for your glass drilling needs, delivering both quality and efficiency.
