Bosch GT300 Carbide Tipped Glass and Tile Drill Bit - 1/4-Inch

The Bosch GT300 is a precision-engineered 1/4-inch carbide-tipped drill bit designed specifically for drilling clean, accurate holes in glass, ceramic tile, and other hard, brittle materials. This specialized bit features a spear-pointed carbide tip that reduces walking and skipping during startup, ensuring precise hole placement on smooth, slick surfaces.

Key Features:

• 1/4-inch diameter carbide tip for drilling glass, mirrors, ceramic tile, and glazed surfaces
• Spear-point tip geometry prevents bit walking and provides accurate starting on slippery surfaces
• Durable carbide construction withstands the heat and friction generated when drilling hard materials
• Works with standard 1/4-inch chuck drills and drill presses
• Ideal for creating holes for fixtures, fasteners, and decorative installations

For best results, use at slow speeds (300-500 RPM) with light, steady pressure and keep the bit cool with water or cutting fluid. The carbide tip maintains its edge through repeated use, making this an essential tool for tile installers, glaziers, and DIY enthusiasts working with delicate materials.
