ER-11 Ultrasonic Core Drills

ER-11 Ultrasonic Core Drills are precision diamond tools designed for ultrasonic drilling machines, commonly used for producing small-diameter, high-accuracy holes in hard, brittle, and delicate materials.

Key Features:

• Shank Type: ER-11 collet-compatible shank, allowing secure, precise mounting in ultrasonic drilling equipment.
• Cutting Edge: Diamond-coated or metal-bonded for long tool life and clean cutting performance.
• Typical Diameters: Often available in sizes from 5 mm to 6 mm, depending on the application.
• Applications:
  • Quartz
  • Sapphire
  • Ceramics
  • Glass
  • Silicon wafers
• Advantages:
  • Minimizes chipping and cracking in fragile materials.
  • High concentricity for precision hole placement.
  • Efficient material removal with reduced heat buildup when used with proper coolant.

Common Use Case:
In ultrasonic machining, the ER-11 ultrasonic core drill is held in the collet chuck and vibrates at ultrasonic frequency while rotating slowly, causing the diamond edge to grind away the material cleanly without generating high stresses.
