Product Description

Specially developed for dry drilling of even the very hardest of materials such as stoneware. For use in all common electric and cordless drills. Fast drilling Due to vacuum diamond coating With special cooling wax You must pause briefly for the drill to cool down when drilling for more than about 30 seconds. Standard ¼“ hexagonal shank, shape E No slipping in the drill chuck Fits every bit holder Notice No water necessary! Speed regulation not necessary. The drill bits are approximately 0.5 mm to 1 mm longer than required. This makes it easier to drill further into the substrate (e.g. a stone drill), preventing damage to the tile Application area Particularly suitable for tiles and stoneware with a thickness of up to 15 mm. Thicker materials up to the specified working length can still be drilled, but more frequent pauses for cooling down will be necessary. Suitable for hard ceramic, thin granite and marble panels and hard-baked bricks. Instructions Spot drilling: Hold at an angle when the bit is moving, then gradually move it to a perpendicular position. Light circular movements increase the drilling speed and preserve the drill bits. Please note: You must pause briefly for the drill to cool down when drilling for more than about 30 seconds or when drilling through thick materials. Regular pauses to allow the drill to cool down generally increase the service life of the drill bits. Only use drill bits in rotating mode! Use powerful drill. Minimum rotation speed 1000 rpm (higher speeds significantly shorten the drilling time and extend the service life of the drill bit) and a minimum of 12 V for cordless tools. Ensure suitable protective equipment is used.
