Robert Bosch Tool Group GT100 Glass Tile Bit 1/8 in

Product Description

The ROBERT BOSCH TOOL GROUP GT100 is a 1/8 inch carbide-tipped drill bit engineered for clean, accurate drilling through glass and tile. The precision tip controls the starting point of the drill, eliminating bit wander and bit walking on smooth, slippery surfaces. A reinforced carbide head resists cracking under load, extending service life compared to standard masonry bits. The three-flat shank locks securely into drill chucks to prevent slipping during operation. Innovative flute geometry accelerates material removal so the bit cuts faster with less heat buildup. Each package contains 3 bits, making it a practical choice for tile setters, glaziers, and contractors who work with glass tile regularly.

This bit is suited for residential and light commercial tile work where precise hole placement is required in glass tile, ceramic tile, and similar brittle surface materials. The controlled-start tip is especially useful when drilling in finished areas where surface damage is not acceptable. Tile installers and glass workers will find the 1/8 inch diameter appropriate for pilot holes, fixture mounting points, and decorative drilling applications.

Key Features

• Precision tip eliminates bit wander and bit walking on glass and tile surfaces
• High-quality carbide tip with reinforced head resists cracking and extends bit life
• Three-flat shank design prevents slipping in drill chuck during use
• Innovative geometry allows faster drilling with reduced heat
• Packaged as a 3-piece set for jobsite continuity

Compatibility

Designed as a replacement or stock bit for use in standard drill chucks accepting a three-flat shank, suitable for glass tile and ceramic tile drilling applications.

Installation Notes

Tile and glass drilling should be performed by a qualified tile installer or glazier familiar with brittle material handling. Use low drill speed and steady, moderate pressure to avoid surface cracking or bit overheating. Keep the work surface and bit cool during drilling by applying water or a wet sponge to the drill point. Secure the workpiece firmly before starting to maintain control through the full depth of the hole.
