Bosch NS300 1/4 in Natural Stone Tile Drill Bit 4 Pack

Product Description

The ROBERT BOSCH TOOL GROUP NS300 is a 1/4-inch carbide-tipped drill bit engineered specifically for natural stone and specialty tile materials. The multi-grind head features multiple cutting edges designed to penetrate harder tile substrates faster than standard masonry bits. A specialized carbide tip centers on the surface before cutting begins, eliminating bit walk for cleaner, more accurate starts. This bit is suited for tile contractors and skilled tradespeople working with natural stone, slate, granite, and similarly hard specialty tile materials where standard bits fall short.

The NS300 is intended for use in natural stone tile, slate, granite, and other specialty hard tile materials that exceed the hardness of standard ceramic tile. It is compatible with hammer drills, making it practical for on-site installation work in residential and commercial tile settings. Each package contains 4 bits. This bit is not recommended for use on porcelain tile. It is best suited for situations where tile hardness demands a purpose-built cutting tool rather than a general-purpose masonry bit.

Installation Notes

Installation should be performed by a qualified tile contractor or experienced tradesperson. Before drilling, ensure the drill is set to the appropriate mode for tile to avoid cracking the substrate. Use water or an appropriate coolant when drilling hard stone materials to reduce heat buildup and extend bit life. Always wear appropriate eye protection when drilling tile.
