PRODUCT ADVANTAGES
Our customer service team is a dedicated, hard-working group specially selected for their enthusiasm and commitment to providing excellent customer service. They offer advice, answer any queries.
Perfect Socket Size:
The 65mm diameter is the industry standard for drilling holes for circular electrical wall boxes and switch sockets in stone walls and backsplashes.
Wet Drilling Efficiency:
Designed for use with water cooling, which clears debris and keeps the diamond segments sharp. This ensures the fastest cut and the longest possible bit life when working on hard granite.
Silver Welded Strength:
The diamond segments are silver brazed to the steel body, providing a strong bond that withstands the torque of drilling large diameter holes.
Universal Fit:
Available with M14 (Euro) or 5/8"-11 (US) threads to fit standard Angle Grinders and wet polishers directly, offering high RPM for clean cuts.
