Montana Brand diamond tile drill bits will give you outstanding performance in ceramic, porcelain, granite, slate, marble, glass, and most hard surface materials. Use these bits to drill holes for water supply lines, drains, electrical wiring, and fixture installation. Great for glass and decorative crafts as well. These bits drill 10 times faster than standard glass and tile drills and will drill 40+ holes per bit before needing replaced. The diamond sintered cutting edge drills clean round holes while the segmented cutting edge improves irrigations and material evacuation. The heavy duty single piece construction combined with the black oxide finish helps insures minimal corrosion and longer life and durability. The bits have a large core ejection slot for easy plug removal and have a reverse thread spiral for continuous water feed. The tri-flat shaft works great in cordless drills.
Legend (in inches unless otherwise noted):
