In the demanding world of precision masonry and industrial fabrication, the selection of the right tooling is the difference between a flawless finish and costly material waste. The 115mm diamond blade and its associated vacuum brazed core drill bits represent a pinnacle of engineering, designed to tackle the toughest porcelain, ceramic, and granite surfaces with surgical precision.
Understanding the technical nuances of vacuum brazed technology is essential for professionals who require chip-free holes and rapid penetration. Whether you are working with delicate onyx or industrial-grade marble, the integration of high-quality diamond grit ensures that your equipment maintains its edge longer, reducing downtime and increasing overall project throughput.
This guide explores the comprehensive application, technical specifications, and operational advantages of utilizing a 115mm diamond blade system, specifically focusing on vacuum brazed diamond core bits that allow for seamless transitions between wet and dry drilling environments on angle grinders and power drills.
The Technology Behind Vacuum Brazed Diamond Tools
Vacuum brazing represents a quantum leap over traditional sintering. By utilizing a vacuum environment to bond diamond particles to the steel body, the bond is significantly stronger and more durable. This technology is what allows a 115mm diamond blade system's core bits to maintain an aggressive cut even when drilling through high-density porcelain or granite.
The result is a tool that offers superior quality, capable of drilling fast and smooth without the need for constant replacement. The vacuum diamond coating ensures that the abrasive particles are held firmly in place, minimizing tool wear and maximizing the number of holes that can be drilled—typically ranging from 60 to 80 holes per bit.
Material Compatibility and Versatility
One of the most significant advantages of the vacuum brazed series is its "all-in-one" capability. Unlike standard bits that are limited to a single stone type, these tools are engineered for a wide spectrum of soft and hard materials. From the delicate textures of onyx and travertine to the extreme hardness of porcelain and ceramic, the versatility is unmatched.
In practical application, this means a contractor can switch from drilling a marble countertop to a ceramic wall tile without changing their core bit. This fluidity reduces the need for a massive inventory of specialized tools and streamlines the workflow on complex job sites where multiple materials are used in tandem.
Furthermore, the inclusion of diamond strips down the length of the barrel provides critical protection for the tool's body. This design ensures that as the 115mm diamond blade associated core bits penetrate deeper, the edges remain sharp and the internal diameter remains consistent.
Precision Engineering for Chip-Free Results
Precision is paramount when dealing with luxury materials like marble or high-end porcelain. The advanced coating of the 115mm diamond blade core system is specifically designed to eliminate the "chatter" often associated with standard drilling, resulting in precise, chip-free holes.
To ensure a clean exit and entry, the core drill barrels are equipped with strategic slots. These slots assist in releasing the core plug during dry drilling, preventing the bit from jamming and reducing the risk of cracking the workpiece, which is a common failure point in non-slotted tools.
By combining #35/40 diamond grit with a premium steel blank, these tools achieve a balance between aggressive material removal and a polished finish. This ensures that the hole requires minimal post-processing, saving time and enhancing the aesthetic quality of the final installation.
Performance Metrics and Efficiency Analysis
When comparing the efficiency of different drilling methods, the vacuum brazed approach consistently outperforms traditional sintered options in terms of speed and longevity. The ability to operate at a minimum work speed of 10,000 RPM allows for rapid penetration without sacrificing the integrity of the diamond bond.
For the professional user, efficiency is measured by the cost-per-hole. By extending the lifespan to 80 holes and reducing the time spent on each cut, the 115mm diamond blade core system provides a lower total cost of ownership compared to lower-grade alternatives.

Operational Guidelines for Maximum Lifespan
While vacuum brazed bits are designed for both wet and dry applications, the optimal approach for extending the life of your 115mm diamond blade core tools is wet drilling. Water serves as a critical coolant, preventing the diamond bond from overheating and flushing away debris to maintain a clear cutting path.
For those operating in dry conditions, the integrated slots in the barrel are vital. Users should intermittently clear the core plug and allow the tool to cool down to prevent thermal stress. Following these guidelines ensures the tool reaches its maximum potential of 80 holes without premature degradation of the brazed layer.
Integration with Modern Power Tools
The versatility of these tools extends to their connectivity. Designed with M14 and 5/8-11 threading, they are perfectly compatible with standard angle grinders. This allows for "hands-free" and "mess-free" drilling, transforming a standard grinder into a high-precision boring machine.
For users who prefer a more controlled approach, these bits can be paired with a 10mm hex shank drill adapter. This enables the use of a standard power drill, which is often preferred for vertical applications or when working in tighter spaces where an angle grinder would be too cumbersome.
Regardless of the power tool chosen, maintaining a minimum work speed of 10,000 RPM is recommended. This ensures that the centrifugal force and cutting speed are sufficient to slice through the material efficiently, preventing the tool from "grabbing" and ensuring a smooth, professional finish.
Technical Specifications and Selection Guide
Selecting the right diameter is crucial for project success. Our range extends from 20mm up to 125mm, ensuring that whether you are installing a small faucet or a large drainage pipe, there is a 115mm diamond blade equivalent core bit for your needs. The standard length of 60mm with a 10mm coating length provides a balanced depth for most residential and commercial applications.
The diamond grit (#35/40) is selected for its ability to balance speed and surface finish. This specific grit size is ideal for the high-density nature of porcelain and granite, ensuring that the tool doesn't just "rub" the surface but actively cuts through it.
Customization is also available; for specialized industrial projects, steel blanks can be manufactured according to specific drawings or samples. This ensures that the tool fits perfectly into automated systems or custom-built machinery.

FAQS
Yes, these vacuum brazed bits are designed for both wet and dry applications. However, wet drilling is highly recommended to extend the lifespan of the tool and prevent overheating. When drilling dry, please use the built-in slots to regularly remove the core plug to avoid jamming.
Vacuum brazing creates a much stronger bond between the diamond particles and the steel body by using a vacuum environment, which prevents oxidation. This results in a more durable cutting edge that lasts longer and cuts faster than traditional sintered bits, especially in hard materials like porcelain.
They are primarily designed for angle grinders using M14 or 5/8-11 connections. Additionally, if you use a 10mm hex shank drill adapter, they can be used with standard power drills, making them highly versatile for different job site requirements.
On average, our high-quality vacuum brazed diamond core drills can drill between 60 to 80 holes. The exact number depends on the hardness of the material and whether you are using wet or dry drilling techniques.
