CRL Three-in-One Glass Drill Bit, Multi-Size Glass Hole Cutter

• Step-Down Feature to Drill 3/16", 1/4", or 5/16" (4.8, 6.4 or 7.9 mm) Holes
• Drills glass, tile, and ceramic
• 400 to 800 RPM recommended

The long taper on the CRL "Three-In-One" Drill provides a step-down drilling action for clean, controlled openings at 3/16", 1/4", or 5/16" (4.8, 6.4, or 7.9 mm). Its 1" (25 mm) tungsten carbide steel blade is designed for glass, tile, and ceramic applications, delivering faster, cleaner holes and longer service life than standard bits. For best results and to extend bit life, use with CRL Diamond Coolant or Pure Gum Turpentine and run at the recommended 400–800 RPM.

Key differentiators:

• Step-down geometry for gradual openings and cleaner cuts
• Tungsten carbide cutting edge for durability when drilling glass and tile
• Versatile size range in a single bit—3/16", 1/4", 5/16"

NOTE: Always wear proper safety gear, including gloves and eye protection, when drilling glass. Work on a flat, horizontal surface. Use a Ground Fault Circuit Interrupter (Cat. No. GF1) whenever using an electric tool with water or coolant. Failure to follow these precautions can result in operator injury.
