The Irwin 1/8" glass and tile drill bit uses a precision-ground tungsten carbide spear point to cut clean, round holes in glass, ceramic tile, mirrors, and marble without chipping or cracking. This smaller diameter is ideal for pilot holes and fine detail work on delicate materials.

• 1/8" cutting diameter with tungsten carbide spear-point tip
• Cuts glass, ceramic tile, mirrors, and marble
• Spear-point design minimizes chipping and breakout at start of cut
• Straight shank fits standard 3-jaw drill chucks
• Long-lasting carbide construction for repeated use

Tip: Mark the drill point with masking tape to prevent wandering, run the drill at a slow speed with light pressure, and keep the surface wet to control heat and extend bit life. Avoid hammer-drill mode on glass or tile - it will crack the workpiece.
