Set of 5 Diamond Core Bits 20/35/40/50/68 mm with M14 Thread for Angle Grinder Soldered Diamond Orange Drilling for Tiles and Marble
You already have the maximum available quantity in your cart.
The set of 5 diamond drilling core bits in diameters 20, 35, 40, 50 and 68 mm covers the most common hole sizes when working with tiles and flooring. All pieces have an internal thread M14 and screw directly onto the spindle of the angle grinder without the need for an additional chuck. The cutting edges are fitted with vacuum soldered diamond grains, which can handle ceramic tiles, cladding, marble, granite, stone slabs, and glass. The tools are designed for dry drilling without water cooling, but can also be used with water for extended work. The set is suitable for tilers, plumbers, and DIY enthusiasts during bathroom or kitchen renovations.
- Diameters in the set – 20, 35, 40, 50 and 68 mm.
- M14 Thread – attachment directly to the angle grinder with M14 thread.
- Vacuum Soldered Diamond – diamond grains firmly bonded to the tool body for cutting hard and abrasive materials.
- Dry and Wet Drilling – drilling without the need for water cooling, although water can extend the lifespan of the tools.
- Dimensions – total length of each piece 60 mm.
- Suitable Materials – marble, granite, stone slabs, ceramics, tiles, cladding, and glass.
- Drilling Procedure – first, position the tool at an angle of 45° and create a groove, then drill vertically at a 90° angle with a slight circular motion.
- Contents of the Package – 1 piece of each diameter 20, 35, 40, 50 and 68 mm.
When working, we recommend starting with the tool tilted approximately 45° to create a crescent-shaped groove in the surface, which will prevent slipping on the smooth glaze. Once the tool is held in the correct position, gradually straighten it to a vertical position and drill with a gentle circular motion and even pressure. This procedure helps maintain a clean edge of the hole and reduces the risk of chipping the glaze. The hard diamond layer retains the shape of the cutting edge even with repeated use. With several diameters in one set, you have the right size for various holes without the need to purchase individual pieces.
The set of 5 diamond drilling core bits with M14 thread is a practical addition to the angle grinder for anyone working with tiles, flooring, or natural stone. The vacuum soldered diamond layer can handle even hard materials such as granite and marble, and the option of dry drilling simplifies work directly at the installation site. Directly screwing onto the spindle of the grinder saves time during the installation of sanitary equipment, kitchen units, and electrical installations. If you occasionally cool the tools with water during prolonged drilling, you will extend their lifespan and maintain cutting ability for future use. The set is suitable for both one-off home repairs and repeated use during renovations.
