Product Description
Why Choose Our Vacuum Brazed Diamond Hole Saw Kit?
💎 Advanced Vacuum Brazing Technology
Unlike standard electroplated diamond hole saws that strip away after just a few drillings, our core drill bits utilize cutting-edge vacuum brazing technology. This metallurgical bond fuses high-density diamond particles securely onto the steel core, providing 3-5x longer service life and extreme heat tolerance under dry-drilling conditions.
🔌 Standard M14 Thread Connection
Equipped with a universal M14 female thread, these diamond hole cutters directly mount onto standard angle grinders without requiring flimsy adapters. This direct-drive setup minimizes lateral runout (wobbling), maximizing your rotational cutting power and creating perfectly round holes.
🔴 Dual Sintered Saw Blades Included
Each heavy-duty set comes complete with 2 pieces of sintered diamond saw blades. Perfect for straight-line trimming, expansion joint slots, or clean edge detailing on ultra-hard engineered slabs, porcelain tiles, quartz, and stone.
💨 Efficient Waste & Heat Clearance
The optimized u-shaped and side slotted openings on the steel body are engineered to rapidly eject dust, stone slurry, and frictional heat. This structural design prevents thermal binding, allowing continuous cutting speed while keeping your workplace cleaner.

1
Can these diamond core bits be used completely dry without water?
Yes. Thanks to the high-performance vacuum brazing technology, these core drill bits are engineered for excellent dry performance on hard tiles and stone surfaces. However, feeding water occasionally during deeper masonry cuts will further prolong the operational lifespan of the diamond matrix.
2
What is the benefit of the M14 connection thread over a standard round shank?
The M14 thread screws directly onto your angle grinder's spindle. This threaded lock delivers a much tighter, more stabilized connection than standard shanks, reducing vibration at high speeds (up to 11,000 RPM) to prevent edge cracking on brittle tiles.
3
How do I get the cleanest hole cutout without walking or skating?
Place your angle grinder at a 45-degree angle to start the initial crescent notch on the tile. Once the groove forms a firm guide, slowly rock the tool to a vertical 90-degree position while swinging gently back and forth to clear stone dust.
