Century Drill & Tool glass and tile bits feature a reinforced micrograin carbide tip that stays sharper longer with less tip breakage than standard glass and tile bits. The 3-flat shank prevents the bit from spinning in the chuck for positive grip and accurate drilling.

• Reinforced micrograin carbide tip for extended life
• 3-flat shank prevents bit slipping in chuck
• 5/16" diameter x 2-3/4" overall length
• For mirror, glass, china, ceramic tile, marble, and slate
• Use at low speed (300-800 RPM) without hammer mode

Tip: Dip the bit in water before drilling and every few seconds during use to reduce friction and extend bit life.
