Efficient and Smooth Drilling
• High-quality diamond segments ensure aggressive cutting while maintaining a clean, burr-free hole edge
• Laser welded for exceptional bonding strength and thermal resistance during heavy-duty drilling
Universal Compatibility
• Supports M22, 1-1/4"UNC, and 1/2"G threads to fit a wide range of drilling machines
• Perfect for both handheld and rig-mounted systems
Engineered Precision
• Designed for exact fitting with minimal runout to ensure accuracy in core extraction
• Optimized segment geometry reduces vibration and improves drilling stability
User-Friendly Design
• Lightweight, humanized structure allows for easy handling and setup
• Simple operation reduces operator fatigue and increases efficiency on-site
Our laser welded diamond core drill bits are suitable for a wide range of heavy-duty construction and industrial applications, including:
Compatible Drilling Machines
• Handheld electric core drill rigs
• Stand-mounted hydraulic or pneumatic core drilling machines
• Compatible with major brands using M22, 1-1/4" UNC, or 1/2” Gas thread systems
Application Scenarios
• Drilling in reinforced concrete slabs and walls
• Creating penetrations for HVAC, plumbing, or electrical installations
• Infrastructure projects: bridges, tunnels, metro stations, etc.
• Brickwork, blockwork, and precast concrete installations
As a professional diamond core drill bit manufacturer, we provide complete OEM and ODM customization for global distributors and engineering contractors:
OEM Services
