Rock-wool is a ceramic material conceived with fibers of molten stone. Compressed blocs of these wool like fibers are, since many years, used in construction industry as an insulating material. Its main features are its thermal insulation (low thermal conductivity), its non-combustibility and fire-resistance. In specific situations it is appreciated for its acoustic performances. Rock-wool is an environmental-friendly material. 1 Kg of Rock-wool is conceived with an energy input of 10 to 20 Mega joules. Due to its insulating capacity and used under normal circumstances, this kg will save some 5 to 10 Mega joules per month, depending on its application (thus a return on energy of 1 to 4 months). In addition is rock-wool not a burden to the environment, as it is a natural and inert product and is rock-wool completely recyclable.

Ceramic fiber blankets are made through process of pricking, heat-shaping, cutting and rolling. They feature high quality of tensile strength, texture uniformity and plane surface, high temperature, chemical corrosion resistance, thermal shock stability and low thermal conductivity. They have low density, good resiliency and excellent sound absorbing and filtering property.             Specifications The Sizes and density not mentioned below are available on request Custom design and cut are also available. Parallel shank twist drills have two helical flutes. The round shank of the drill has approximate the same diameter as the diameter of the cutting end. Extremely useful for drilling holes in metal, wood and plastic applications. Hardened and tempered to give you good life in general purpose engineering. Parallel shank jobber series twist drills are available in standard pack of ten depending on size.
