Diamond Core Drills For Ceramics

Metal Bond Diamond Core Drills are preferred for drilling Ceramics

Diamond core drills for ceramics are designed to cut clean, precise holes in a very hard, brittle materials. Drilling alumina, zirconia, silicon nitride, silicon carbide are very hard and brittle so it requires diamond tooling to avoid cracking, chipping.

 

• Diamonds are embedded in a sintered metal matrix.
• Longer tool life, more durable for continuous or production drilling.
• Suitable for large diameters and deep hole drilling in ceramic.
• Require proper coolant to prevent glazing and overheating.

 

  Requirements for Ceramic Drilling

 

• Coolant: Always use coolant through the drill to reduce heat and prevent cracks.
• Speed: Run at moderate RPM (varies with drill size: small drills = higher RPM, large drills = lower RPM).
• Feed Pressure: Light pressure—let the diamond cut. Excess force causes edge chipping.
• Start Technique: Prevent drill from dancing on top of the material, use guides or a starter hole.
• Wall Thickness: Thinner-walled drills reduce heat and improve cutting efficiency on ceramics.
• Coolant channels for continuous coolant flow.

 Electronics & Technology

• Semiconductors – substrates, insulators, and packaging.
• Piezoelectric ceramics – sensors, actuators, ultrasound devices.
• Superconductors – high-temperature superconducting ceramics.
• Dielectrics – capacitors and circuit boards.

 Medical & Dental

• Dental implants and crowns – zirconia, alumina.
• Bone substitutes and prosthetics – biocompatible ceramics like hydroxyapatite.
• Surgical tools and joint replacements – wear-resistant ceramics.

 Aerospace & Defense

• Thermal protection systems – heat shields on spacecraft (silica tiles, advanced composites).
• Armor – ceramic body armor plates, vehicle armor (boron carbide, alumina).
• Turbine components – ceramic matrix composites for jet engines.
