The SPERO SFT-76 diamond core drill features a diameter of 76 mm with a drilling length of 350 mm and a 1 1/4 UNC internal thread connection. This dry drilling diamond drill is designed for concrete and stone applications where water cooling is impractical or not permitted. The special design includes a milled spiral groove along the drill pipe, allowing for efficient dust extraction and cooling while providing additional space for drilling debris. This high-quality construction makes the drill suitable for drilling in reinforced concrete, channel slabs, aerated concrete, and various stone materials without water cooling. The seamless drawn drill pipe construction ensures exceptional stability and professional performance during operation. The diamond segments feature laser-welded teeth for enhanced durability and consistent cutting performance. For optimal dry drilling functionality, this drill requires compatible drilling machines with soft impact function and internal dust extraction, along with an M-class vacuum cleaner with impact function. The drill can also be used with water cooling for all types of stone when standard wet drilling conditions are preferred. To maximize lifespan and performance consistency, operation from a drill stand is recommended, along with periodic sharpening using a dressing stone to maintain cutting efficiency. The robust construction and specialized design make this diamond core drill particularly valuable for applications in inhabited buildings, overhead ceiling work, or environments where water use is strictly prohibited.
