| Long Description | The exothermic welding process is a method of making electrical connections of copper to copper or copper to steel in which no outside source of heat or power is required. In this process, granular metals (granular copper oxide and aluminium) are placed from a container into a graphite crucible and ignited. This process is a cost effective method of completing a high quality electrical connection and is also simple to follow. | Featuring a constant pitch - first choice for cutting thin sheet materials up to 3mm thick. For producing high quality holes in wood, steel, brass, bronze, cast iron, aluminium and plastic. Featuring an hardened HSS cutting edge welded to a tough alloy steel body. Heavy duty shatter-resistant construction; virtually unbreakable. 6 teeth per inch.38mm (11/2”) cutting depth. | The Sharpie 30003 Permanent Marker features blue permanent ink and a fine point tip that produces precise, consistent markings for labeling, writing, and general-purpose applications. The quick-drying alcohol-based ink is water-resistant, fade-resistant, and suitable for use on paper, plastic, metal, wood, glass, and other surfaces. Designed with a durable plastic barrel and pocket clip cap, the marker provides reliable everyday performance in offices, schools, warehouses, workshops, and industrial environments. The ink is AP-certified non-toxic and complies with ASTM D-4236 safety standards. |
