It is widely used by contractors, stone fabricators, plumbers, electricians, and renovation specialists who require smooth, accurate holes with minimal surface damage.
Key Features
✔ High-Quality Diamond Cutting Rim
The cutting edge is crafted with premium synthetic diamonds for superior hardness and durability. This ensures fast penetration and clean drilling through concrete, stone, ceramic, brick, block, and masonry materials.
✔ 1-Inch Precision Hole Diameter
Ideal for creating small-diameter holes for pipes, cables, bolts, anchors, sensors, conduits, or drainage systems. The bit maintains excellent dimensional accuracy for professional-grade results.
✔ Strong & Heat-Resistant Steel Barrel
The specially heat-treated steel body provides strength, stability, and resistance to distortion during long drilling sessions. It ensures consistent performance even under heavy load or continuous drilling.
✔ Smooth Drilling with Low Vibration
The diamond grinding action produces less vibration and noise compared to hammer bits. This helps prevent cracks, chipping, or damage to the surrounding surface - especially important for tiles, marble, granite, and finished stone.
✔ Suitable for Wet & Dry Drilling
For most applications, wet drilling is recommended as it increases cutting efficiency, reduces dust, and greatly extends tool lifespan. Dry drilling is also possible depending on the machine and material.
