Tile drill bits: ceramic, porcelain and wet or dry choices

Compare the named tile application

This table preserves each manufacturer's scope. The soft-tile entry is not a porcelain recommendation, and a dry carbide example does not make a wet diamond bit suitable for dry use.

Match cooling and machine together

RUBI's range guide says water is essential for EASYGRES. Include the required water supply or guide arrangement in the buying check rather than pricing the cutting accessory alone. Bosch's no-cooling instruction above belongs to its named carbide family; it is not a general rule about tiles.

RUBI also distinguishes DRYGRES 4DRILL accessories for drills from DRYGRES angle-grinder products. A dry label does not identify the holder or operating speed. Check the exact format and permitted machine instead of assuming an adapter makes two versions equivalent.

Keep the tile and the backing material separate

A tile surface can cover a different substrate. Establish the bit and operating requirements for each material instead of applying a concrete-drilling instruction to the tile. Bosch's Hard Ceramic FAQ explicitly prohibits impact while drilling tile; its tool-category labels should not be read as permission to use that mode.

Search Amazon with the identified tile material, hole diameter and exact family or article code. Confirm that the selected variant includes any required guide and matches the manufacturer instructions. Product photographs and a broad ceramic-and-masonry title are insufficient evidence for a hard-porcelain application.
