•High Durability for Heavy-Duty Workloads
The core bit is manufactured with premium sintered diamond segments bonded to a strong carbon steel substrate. This structure provides excellent wear resistance, allowing the bit to withstand prolonged drilling in hard materials without rapid segment loss or deformation.
•Wet & Dry Drilling Flexibility
It can be used in both wet and dry drilling environments, giving you flexibility on different job sites. For long coring runs or very hard substrates, water cooling is strongly recommended to control temperature, reduce segment glazing, and significantly extend the tool’s lifespan.
•Wide Material Compatibility
Designed for versatility, this sintered diamond core drill bit works efficiently on concrete, masonry, hard brick, marble, granite, ceramic tile, and even glass. One tool can cover multiple tasks, which helps simplify inventory and lowers consumable costs for contractors and fabricators.
•Accurate, Clean Hole Cutting
Thanks to its stable structure and optimized diamond matrix, the bit produces smooth, accurate holes with reduced chipping and breakout on both entry and exit. This is especially valuable when drilling visible surfaces such as countertops, façade panels, or high-end tile installations.
•Universal Machine Compatibility
The bit is available with multiple shank options, including M10, M14, 1/2" GAS, and hexagonal connection. This makes it compatible with a wide range of hand drills, table drills, angle grinders (with adapter), and common core drilling machines used on construction and stone fabrication jobs.

To maximize drilling speed, tool life, and hole quality, we recommend the following practices:
•Start with light feed pressure
Position the bit carefully and begin drilling with gentle pressure until the drilling path is established. This helps avoid wandering and misalignment.
•Increase pressure gradually
Once the bit is aligned and cutting steadily, gradually increase the downward force. Let the diamonds do the work—avoid pushing too aggressively, which can cause overheating and premature wear.
•Slow down near breakthrough
As you are about to penetrate through the material, reduce feed speed. This minimizes exit chipping and helps protect the back side of walls, tiles, or slabs.
•Use water cooling whenever possible
Although the bit supports dry drilling, applying water as coolant greatly reduces heat build-up, flushes out debris, and extends the lifespan of the diamond segments.
•Follow proper safety practices
Always wear safety glasses, gloves, hearing protection, and, for dry drilling, suitable dust protection. Ensure the workpiece is securely clamped before drilling.
•Construction & Masonry
Ideal for creating holes in concrete, reinforced concrete, and brickwork for anchors, pipes, cables, HVAC penetrations, and fastening systems on building sites.
•Stone Fabrication & Countertop Shops
Suitable for precision drilling in granite and marble slabs, countertops, and cladding panels where clean edges and accurate positioning are critical.
•Tile, Ceramic & Glass Work
Provides clean, controlled cutting of porcelain, ceramic, and glass tiles, helping reduce cracking and edge damage in bathroom, kitchen, and façade installations.
•DIY Projects & Professional Renovation
Reliable for both professionals and advanced DIY users working on renovation projects that involve drilling through hard materials in limited quantities.
Vacuum brazed core bits are excellent for fast cutting in ceramics and tiles, especially for shorter jobs or lighter duty work. However, when you are drilling hard, dense materials such as granite, marble, and reinforced concrete, sintered diamond bits offer distinct advantages:
•Longer Lifespan Under Heavy Loads – Sintered segments contain multiple diamond layers, so new diamonds are exposed as the bond wears, maintaining cutting ability over a longer period.
•Better Stability in Continuous Drilling – The segment structure is designed to handle sustained pressure and higher drilling lengths without rapid performance drop-off.
•More Cost-Effective for Demanding Projects – For contractors frequently coring hard materials, the longer life and consistent performance of sintered bits result in a lower cost per hole compared to many vacuum brazed options.
For heavy-duty drilling tasks, sintered diamond core bits are often the preferred choice.
• Can this core bit be used for dry drilling?
Yes. The sintered diamond core bit can be used for both dry and wet drilling. However, using water for cooling is strongly recommended, especially in long drilling runs or very hard materials, as it reduces heat and significantly extends the service life.
• What machines is it compatible with?
The bit can be mounted on hand drills, table drills, and other drilling machines that accept M10, M14, 1/2" GAS, or hexagonal shanks. Adapters can also be used to match specific tools in your workshop or on site.
• What materials can I drill with this bit?
It is suitable for granite, marble, natural stone, concrete, masonry, hard brick, ceramic tile, and even glass. For extremely brittle materials, we recommend wet drilling and controlled feed pressure.
• How do I prevent overheating during drilling?
Use water as a coolant whenever possible, avoid excessive force, and allow short pauses during long holes to let the bit cool. Proper cooling and moderate pressure are the keys to preventing overheating and segment glazing.
• Do you support OEM or customized sizes?
Yes. We can supply custom diameters, lengths, and thread types, as well as private label and OEM packaging for distributors and project contractors.
