The SPERO SFT-112 diamond core drill is designed for dry drilling applications in concrete and stone where water cooling is impractical or prohibited. With a diameter of 112 mm and an effective drilling length of 350 mm, this high-quality diamond core drill features a 1 1/4 UNC internal thread for secure attachment to compatible drilling machines. The helical groove milled into the seamless steel cylinder allows for efficient dust extraction and cooling while improving clamping freedom. This design ensures exceptional stability and professional performance. The diamond segments are laser-welded to the core drill for reliable operation. The SPERO SFT-112 is specifically developed for drilling machines with a soft impact function and integrated dust extraction. It works effectively in reinforced concrete, channel ceilings, aerated concrete, and various stone materials in dry operation. For optimal performance and extended lifespan, operation from a drilling stand and periodic sharpening with a dressing stone are recommended. The diamond core drill can also be used with water cooling for all stone materials. Compatible drilling machines include models with 1 1/4 external threads, micro-impact function, and internal dust extraction through the drill spindle. This tool is particularly suitable for drilling in inhabited environments, overhead ceiling applications, or locations with strict water usage prohibitions.
