Tormek equipment and tools are designed to avoid those all too familiar issues that you run into with other sharpening technologies. Thanks to the low speed on all of their machines, there is no risk that the edge becomes overheated and loses its hardness. On the Tormek T-4 and T-8, the edge is continuously cooled with water during the sharpening. On the Tormek T-2, the fine-grained diamond wheel and slow rotation prevent the edge from becoming overheated. The industrial Tormek motor maintains an ideal RPM, regardless of load. The reliable self-adjusting gear design ensures you always get the right torque, without excessive force and wear to the system. Sometimes power comes at the detriment of the life of the sharpening equipment, but Tormek builds from materials meant to last.
