1. **Precision Brazing with Coarse Grit**: Featuring 40 grit carbide brazing, these drill bits deliver sharp, precise cuts through hard materials like glass, ceramic, and granite. The robust brazing ensures durability, resisting wear even on the toughest surfaces—ideal for long lasting, professional performance in any project. 2. **Efficient Chip Removal**: The specially designed large flute structure enhances debris clearance, preventing clogging and overheating during drilling. This innovative design ensures smooth, rapid progress with minimal resistance, reducing friction to maintain cutting efficiency and deliver clean, burr holes every time. 3. **Dual Flexibility for Wet Dry Drilling**: Adapts to any work environment with versatile wet or dry drilling capability. Use dry for quick, dust tasks on tiles or glass, or apply water for wet cooling when tackling dense materials like marble or quartz—maximizing performance while protecting both the bit and workpiece. 4. **Non Slip Shank for Secure Operation**: The triple anti slip shank provides a tight, vibration fit in both handheld and bench drills, ensuring stability and safety during operation. Say goodbye to slipping or wobbling, even at speeds, for controlled, precise drilling in every application.
