Drill Bits for Glass, Tile, & Porcelain

Drill Bits for Glass, Tile, & Porcelain

Drill smooth holes in glass, ceramic, and porcelain surfaces with these bits. Choose a solid bit with or without flutes for drilling smaller holes in soft to medium-hard tile and unhardened glass, or use a hollow diamond-tipped core bit for creating larger holes in hard tile and glass. For best results and to avoid damaging the workpiece, use low drilling speeds and apply a coolant such as water or turpentine while drilling.

Arrow Carbide-Tip Bits

Arrow Carbide-Tip Bits

These bits have an arrow tip that helps keep the bit from walking when starting a hole and allows the bit to drill holes larger than the bit diameter. They are recommended for drilling small holes in soft to medium-hard tiles, porcelain, ceramics, and unhardened glass.

Carbide Tipped Bits

Carbide Tipped Bits

With flutes for efficient evacuation of dust and chips, these spiral drill bits are a good choice for drilling small holes in hard porcelain tile. Some bits have a spear-shaped tip that helps keep the bit from walking when starting a hole.

Diamond Tipped Core Bits

Diamond Tipped Core Bits

Core bits have a hollow center surrounded by cutting edges that have been coated with diamond abrasives at the tip, allowing the tool to grind through very hard materials. The bit cuts through the perimeter of the hole during drilling, leaving a solid slug in the center which can be ejected through a slot on the side of the drill bit. They are well suited for drilling large holes in hard materials such as porcelain.
