3.3-9.5mm conical file

For sharpening gouges, carving or turning tools, and curved blades. Fine grit. With over 25 years of experience, DMT (Diamond Machining Technology), based in the USA, is a leader in the manufacture of diamond sharpening tools. DMT products are manufactured with high precision, are also very durable and extremely efficient at a reasonable price. The industrial diamonds used by DMT in the manufacture of their sharpening tools are monocrystalline, which are more abrasive and wear-resistant than the lower-quality polycrystalline diamonds used in inexpensive sharpening stones. Diamond sharpening guarantees astonishingly fast results, even on high-hardness steels such as high-speed steel (HSS), tungsten carbide steels, and ceramics. These qualities make DMT products suitable for all hand tools, as well as woodworking machinery, knives, etc. Because they wear very little, the working surface remains undeformed, making DMT diamond stones remarkably effective for flattening the sole of a plane, squaring the edge of a chisel, plane iron, scraper, etc. Important: Diamond stones must be kept constantly wet with water during use.
