🏗 Applications – Professional Use
BMTG diamond core drill bits are designed for percussion-free diamond drilling in:
Designed for drilling holes for:
plumbing installations
electrical installations
ventilation and air-conditioning systems
sanitary and gas installations
heating systems
technical and industrial penetrations
Also suitable for:
creating door and window openings
renovation, refurbishment and demolition work
extracting core samples for structural testing and asphalt pavement analysis
⚙ Laser-Welding Technology – A Quality Advantage
The diamond segments are permanently bonded to the core barrel using fiber laser welding on modern CNC machines.
This provides:
very high mechanical strength of the segment-to-barrel bond
high thermal resistance
the ability to drill both dry and wet
safe operation under heavy loads
Each bond between the diamond segment and the core barrel undergoes strength testing using torque measurement equipment. The results achieved typically exceed standard market requirements.
