High-speed steel tools are used for turning, drilling, grinding, milling, countersinking, cutting, tapping, and sawing. They can withstand high temperatures and are used for cutting hard materials like steel, wood, and concrete. Lathe and woodworking tools are made from high-speed steel, as well as rotary cutting bits for routers and saw blades. Tungsten and carbide coatings are used to increase tool life and cutting power.
There are several types of high speed steel tools found in turning tools, drilling tools and grinding tools. Other types of high speed steel tools are milling machines, countersinks and cutting tools. Taps, dies, and even saw blades make up groups of these tools. Primarily used for steel and metal cutting and machining, high-speed steel woodworking tools are also available for a variety of uses.
The use of high speed steel tools allows tool makers to create tools that will perform without damage on very hard steel, wood projects and workpieces. Drill bits for wood, steel and masonry are three types of high speed steel tools. The special steel allows a sharp cutting edge to withstand high temperatures and continue cutting for many uses. On very hard concrete or stone bits, a special carbide coating is commonly applied to the cutting edge to add extra cutting power to the bit. Tungsten is also used on many high speed steel tools to increase tool life and longevity when used on extremely strong materials.
Many lathe tool bits are made from high speed steel. Turning tool bits are used to create many components on the lathe without requiring the bits to be re-sharpened. Special hardening methods are used on the tips to create an extremely strong cutting edge capable of cutting through the hardest steels. Wood lathes also require a very strong turning tool to withstand the massive amounts of heat created when turning a hardwood. The various gouges, parting tools, and other lathe tools used to create woodturnings are tools made from high-speed steel.
Routers use high-speed steel tools in the form of rotary cutting bits to cut and remove material from large blocks of billet steel and aluminum. Operating at low to medium speeds, these tools must be very sharp and flawless to create a quality product. Even the slightest burr on the surface of a router cutting tool can cause imperfections in many areas of a single job. Unlike a computer numerically controlled lathe which uses a ceramic cutting tool, the milling machine uses a rotating steel cutting tool to make the cuts. Saw blades designed for both wood and steel cutting are high-speed steel tools that can stay sharp through many cutting cycles.
