Diamond Core Drills For Quartz
Metal Bond Diamond Core Drills are preferred for drilling Quartz
Diamond core drills for quartz are designed to cut clean, precise holes in a very hard, brittle material. Quartz (fused silica) an ultra-pure, non-crystalline form of silicon dioxide produced by melting natural quartz or synthetic silicon tetrachloride at high temperatures is hard and brittle so it requires diamond tooling to avoid cracking, chipping, or premature tool wear.
- 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 quartz.
- Require proper coolant to prevent glazing and overheating.
Requirements for Quartz 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 quartz.
- Coolant channels for continuous coolant flow.
Typical Applications
- Semiconductor quartz ware fixtures.
- Electronics and optics.
- Mineral and gemstone work.
- Scientific and lab quartz tubing/ware.
