The ROBERT BOSCH TOOL GROUP NS500 is a 3/8-inch carbide-tipped drill bit engineered specifically for natural stone and specialty tile materials. The multi-grind head features multiple cutting edges that cut aggressively through hard stone surfaces while a specialized carbide tip centers on contact, preventing bit walk on smooth tile faces. This bit is intended for use in rotary or hammer drill applications where conventional masonry bits struggle. It is appropriate for use by tile setters, stone fabricators, and skilled tradespeople working with dense natural materials such as slate and granite.
The NS500 is designed for drilling into natural stone tile, slate, granite, and other specialty tile materials that are harder than standard ceramic tile. It is not recommended for use on porcelain tiles. The bit is compatible with hammer drills, making it a practical choice for job-site drilling where variable-speed hammer drills are standard equipment. This SKU ships as a 4-pack, providing multiple bits for extended use on larger stone tile installations.

This bit should be installed by a qualified tile setter or experienced tradesperson familiar with stone drilling techniques. Before drilling, power down and secure the workpiece or verify that substrate supports are stable. Use water or an appropriate coolant when drilling into dense stone to manage heat buildup and extend bit life. Follow tool manufacturer guidelines for drill speed and feed rate settings when using hammer drill mode on natural stone.
