Description
Product Overview
The BRSCHNITT Dry Diamond Core Drill Bit Set is a precision‑engineered solution for demanding drilling applications. Each set contains two 25mm (1 inch) triangle‑shank bits crafted from high‑grade steel and coated with vacuum‑brazed diamond particles. The diamond coating, with a height of 10mm, provides exceptional resistance to heat and friction, extending tool life even under continuous dry‑drilling conditions. The spiral groove at the tip promotes efficient chip removal, while the built‑in wax core aids cooling and lubrication without the need for water. With a total length of 65mm, the bits balance rigidity and flexibility, allowing smooth entry into hard substrates such as porcelain tile, ceramic, granite, marble, concrete, glass, and hard plastics. The compact dimensions (0.98 x 0.98 x 2.56 inches) and lightweight design (4.59 ounces) make the set easy to handle and store.

Usage
Designed for versatility, these core drill bits fit standard electric drills, hand drills, bench drills, and even angle grinders when equipped with the appropriate chuck. Ideal for professional tile installers, countertop fabricators, and DIY renovators, the bits excel in creating clean, round holes for plumbing, electrical, and HVAC installations. Because the bits are optimized for dry drilling, they eliminate the mess and setup time associated with water‑based drilling, making them perfect for indoor environments where water use is restricted. Users should secure the workpiece on a stable surface, select the appropriate speed (typically 1500–2000 RPM for 25mm bits), and apply steady pressure. The spiral groove and wax core work together to evacuate debris, reducing the risk of overheating and ensuring a smooth finish.

FAQ
Can I use these bits with a water‑cooled drill?
Yes, although the bits are optimized for dry drilling, they can be used with water if desired. The diamond coating tolerates moisture, but using water may reduce the self‑lubricating benefit of the internal wax.
What material is the core made of?
The core is forged high‑strength steel, providing rigidity while the vacuum‑brazed diamond particles are bonded to the surface for cutting performance.
How do I prevent the bit from overheating?
Maintain recommended drill speeds (1500‑2000 RPM for 25mm bits), apply steady pressure, and allow the built‑in wax core to dissipate heat. Periodic pauses during long cuts also help manage temperature.
Are these bits compatible with angle grinders?
Yes, when fitted with the appropriate drill chuck for an angle grinder, the triangle shank ensures a secure connection.
What is the warranty period?
All BRSCHNITT core drill bits come with a 12‑month limited warranty covering manufacturing defects.
