Six electroplated diamond twist drills for clean, controlled holes in hard materials like stone, pearls, glass, and ceramics. Each drill has a standard 3/32" shank for most rotary handpieces. Use with a small amount of water for lubrication and longer bit life.

• Diamond type: Electroplated diamond cutting surface for fast starts and steady cutting
• Shank size: 3/32" (fits common rotary handpieces)
