Description
Product Overview
The FACHLICH Diamond Core Drill Bit is a premium masonry core drilling solution designed for demanding applications in construction, renovation, and specialty tile work. Measuring 127mm in diameter with a 15mm diamond height, the bit features a robust 5/8″-11 thread connection that fits securely into standard angle grinders and drill machines. Engineered with #35/40 diamond grit, the cutting surface delivers exceptional hardness and wear resistance, allowing it to penetrate hard materials such as granite, marble, porcelain, and high‑density ceramic tiles with minimal effort. The bit’s 4 mm lightning‑tooth cutter head is specifically shaped to create a wide, clean channel for debris evacuation, reducing heat buildup and extending the life of the diamond coating. Its total length of 60mm, with a working length of 35mm, provides ample reach while maintaining a compact profile that is easy to handle and store. The product dimensions of 2.36 x 1.97 x 1.97 inches and a weight of 1.76 pounds make it portable for on‑site use, and the vacuum‑brazed diamond technology ensures a stable bond between the diamond particles and the steel substrate, delivering consistent performance over thousands of drilling cycles.

Usage
This core drill bit excels in a variety of real‑world scenarios. Whether you are installing floor heating systems, creating openings for plumbing and electrical conduits, or preparing precise cutouts for countertop installations, the bit provides reliable, repeatable results. It is ideal for both dry drilling and wet drilling; using water as a coolant can further prolong the bit’s lifespan by reducing friction and flushing away stone dust. The bit is compatible with most angle grinders and drill machines when equipped with the appropriate adapter, making it a versatile addition to any contractor’s toolbox. Professionals in the tile‑laying, stone‑fabrication, and masonry trades will appreciate the bit’s ability to produce smooth, round holes with minimal chipping, while DIY enthusiasts will find the straightforward setup and operation suitable for home improvement projects such as installing wall anchors or creating custom tile designs.

FAQ
Can this bit be used for wet drilling?
Yes, the bit is designed for both dry and wet drilling. Using water as a coolant helps reduce heat, extend the diamond coating life, and improve chip evacuation.
What size adapters are needed for different machines?
The bit comes with a standard 5/8″‑11 thread. If your tool uses a different arbor size, a simple adapter sleeve can be purchased to convert the connection without compromising performance.
How often should the bit be cleaned during use?
For optimal performance, pause every few minutes to clear accumulated stone dust from the cutting surface. A soft brush or compressed air can be used, and if you are wet drilling, flushing with water will keep the bit clean.
Is the bit suitable for cutting through reinforced concrete?
While the bit excels in stone and tile applications, it is not intended for reinforced concrete. For concrete drilling, a carbide‑tipped core bit is recommended.
What warranty does FACHLICH provide?
FACHLICH offers a limited one‑year warranty covering manufacturing defects. If the bit fails under normal operating conditions within this period, a replacement will be provided.
