Bosch NS2000 Drill Bit Set, 4-Piece, HSS

Bosch natural stone tile bits are designed for decorative specialty tiles that feature natural stone and other harder materials. The bits provide a multi-grind head with multiple edges. With these specially ground bit tips, the bits deliver 20% faster drilling in natural stone tile and other hard tile than standard glass and tile bits. Manufactured with high-quality carbide, these bits were constructed for natural stone tile, slate, granite and specialty tile. The 3/8 in bits and above provide a three-flat shank for superior bit grip.
