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. 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 Application area 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. |
