Bosch GT1000 1 Inch Glass Tile Drill Bit 3-pack

Product Description

The ROBERT BOSCH TOOL GROUP GT1000 is a 1-inch carbide-tipped drill bit engineered for clean, accurate drilling through glass tile and similar hard, brittle surfaces. The precision tip design eliminates bit wander and bit walking at the start of the drill, which is one of the most common failure points when working on glazed or polished tile. The reinforced carbide head resists cracking under load and extends service life compared to standard masonry bits. The three-flat shank locks securely into most drill chucks to prevent slippage during use. Sold as a 3-pack, this bit is a practical option for tile setters, plumbers, and electricians who regularly drill penetrations through glass or ceramic tile surfaces.

The GT1000 is suited for residential and light commercial applications where drilling through glass tile, ceramic, or other hard surface materials is required. Typical scenarios include fixture mounting, drain rough-ins through tiled surfaces, and panel or conduit penetrations through decorative tile walls. The 1-inch diameter is commonly used for standard plumbing and electrical rough-in work where tile penetration is necessary. This bit is appropriate for use with standard corded or cordless drills and hammer-free drilling technique on glass and tile materials.

Installation Notes

Glass and tile drilling should be performed by a qualified tile setter, plumber, or electrician using a corded or cordless drill set to non-hammer mode, as impact or hammer action will crack glass tile. Apply consistent, moderate pressure and use water or cutting fluid to manage heat buildup at the bit tip. Secure the workpiece before drilling to prevent tile movement or cracking. Always wear appropriate eye protection when drilling brittle surface materials.
