Wet Diamond Core Drill Bit 4" Diameter, Core Bit Turbo Laser-Welded Segments for Concrete, Masonry, Stone, Brick, Block, 1-1/4"-7 Thread, 15-3/4" (400mm) Drilling Depth

Diamond Core Drill Bit, a handy tool designed for drilling tasks across a variety of hard surfaces. Engineered with precision, this core drill bit is ideal for professionals and DIY enthusiasts alike.

Key Features:

Laser-Welded Segments: Advanced laser welding technology ensures the high-frequency welded diamond teeth remain sharp and wear-resistant through tough materials.

Efficient Drilling with Smooth Operation: The premium diamond material and aluminum alloy core contribute to smooth drilling experiences including formulated chip removal slots and a stable concentric shaft for effective coring.

Standard Compatibility: The industry-standard 1-1/4”-7 thread is compatible with most core drilling machines, ensuring you can integrate it seamlessly into your tool collection.

User-Friendly Operation: Optimized for wet drilling – water use prolongs the bit's life and improves performance. To use, simply initiate drilling at a vertical position and maintain steady pressure as you dig deeper.

How to Use:

1. Preparation: Ensure your drill is compatible with a 1-1/4”-7 thread bit. For best results, set up a water source to keep the bit cool.

2. Begin Drilling: Start drilling at a vertical position. This ensures greater control and accuracy.

3. Deep Drilling: Maintain a steady downward pressure while drilling deeper into the material.

4. Chip Removal: Allow the chip removal slots to function effectively by lifting the drill bit occasionally to clear debris.

Applications:

- Ideal for installations such as air conditioning pipes, range hoods, ventilation hoses, stair railings, road, and airport construction.

- Suitable for high-end constructions involving hard materials like cured concrete with rebar, marble, masonry, rock, brick, tile, cinder block walls, asphalt, stone, and many other materials
