Bosch GT800 3/4 in Glass Tile Drill Bit 3-pack

Product Description

The ROBERT BOSCH TOOL GROUP GT800 is a 3/4-inch carbide-tipped drill bit engineered for clean, controlled drilling through glass, ceramic tile, and similar hard, brittle surfaces. The precision tip design eliminates bit wander and bit walking at the start of the bore, which is the most critical phase when drilling smooth or glazed surfaces. A reinforced carbide head resists cracking under load and extends service life compared to standard masonry bits. The three-flat shank prevents rotation in the chuck for a secure, positive grip during use. Sold in a 3-pack, making it practical for ongoing trade use.

This bit is suited for tile setters, plumbers, electricians, and general contractors drilling penetrations through wall tile, backsplash glass, decorative tile, and similar materials in both residential and light commercial settings. The innovative cutting geometry accelerates material removal while maintaining hole quality, reducing the number of passes and rework on finished surfaces. It is a practical choice wherever controlled entry into brittle material is required without cracking or spalling the surrounding surface.

Key Features

• Precision tip geometry prevents bit wander and bit walking on smooth or glazed surfaces
• High-quality carbide tip with reinforced head resists cracking and extends bit life
• Three-flat shank locks securely in the chuck and prevents rotation during drilling
• Innovative cutting geometry allows faster material removal through glass and tile
• 3/4-inch diameter suitable for standard penetration and anchor applications in tile
• Sold in a 3-pack for continued productivity on multi-penetration jobs

Compatibility

Designed as an OEM-style specialty bit for use in standard drill chucks accepting a three-flat shank, appropriate for drilling glass, ceramic tile, and similar hard brittle surfaces.

Installation Notes

Glass and tile bits should be used at low to moderate drill speeds without hammer mode engaged, as impact action will crack brittle surfaces. Applying water or a compatible cutting fluid at the drill point helps manage heat and extends bit life. Secure the workpiece firmly before drilling to prevent shifting. Always wear appropriate eye protection when drilling glass or tile due to the risk of material fracture and debris.
