Total TAC430501 50MM Hole Core Bit

It excels at drilling through concrete (including reinforced concrete), brick, and stone thanks to its diamond-tipped design, which provides durability and consistent cutting performance in hard substrates.

Key specs include a 50mm hole diameter and a diamond-tipped cutting edge engineered for fast, clean hole creation. It is built for durability and precision, tailored for heavy‑duty industrial and construction use.

The 50mm version (this model) creates smaller holes and typically requires less material removal per pass, while the 60mm and 80mm variants remove more material per pass and are suited for larger holes. For direct side-by-side options, you can explore the 60mm and 80mm TAC variants on Fepy: 60mm – https://fepy.com/product/total-tac430502-60mm-hole-core-bit and 80mm – https://fepy.com/product/total-tac430503-80mm-hole-core-bit.

Ideal for installations requiring 50mm access holes, such as running electrical conduits, plumbing lines, or anchors through concrete, brick, or stone in both residential and commercial projects.

Attach the core bit to a compatible drill arbor or chuck, ensure the bit is perpendicular to the workpiece, and start at a low speed to center the hole. Increase to steady drilling with controlled feed pressure, keeping the drill aligned to prevent wandering. Use appropriate drilling settings (hammer mode if using a hammer drill) and let the bit do the cutting with minimal forcing.

Wear safety glasses or a face shield, hearing protection, and gloves. Secure the workpiece, keep hands clear of the cutting area, and avoid overheating by drilling with moderate pressure and allowing for cooling breaks. Be mindful of hidden reinforcement or debris inside walls and floors.

Water cooling is recommended in many setups to reduce dust, extend bit life, and help manage heat. If water cooling isn’t available, use the drill at controlled speeds and avoid sustained high-pressure drilling to prevent overheating.

Diamond-tipped core bits are designed to cut through hard materials faster and with greater longevity than standard carbide bits, which translates to quicker hole creation and fewer bit changes in demanding materials. Expect smoother cuts and longer bit life when used as intended.

After use, clean off dust and debris, dry the bit thoroughly, and store it in a protective case. Periodically inspect the diamond tip for wear and avoid dropping the bit, which can cause chipping or misalignment.

Yes. Rebar or metal debris can quickly dull or damage the diamond edge. If you encounter metal inside the workpiece, pause, reassess, and consider pre‑drilling or using a pilot hole to avoid excessive stress on the bit.
