Introduction:
The tool bit is a non-rotary cutting tool used in metal lathes Wholesale New Orleans Saints Jerseys , shapers, and planers. Such cutters are also often referred to by the set-phrase name of the single-point cutting tool, as distinguished from other cutting tools such as a saw or water jet cutter. The cutting edge is ground to suit a particular machining operation and may be re-sharpened or reshaped as needed. While it is cutting ground tool bit is held rigidly by a tool holder.
Application of tool bits according to their types:
There are many types and use of the tool bits. Some are countersink bits, tiles and glass bits Wholesale Saints Jerseys , masonry bits, twist and HSS bits, multi-purpose bits and wood or brad point bits. Their use is here down below.
Countersink bits:
Fluted countersinks come in several sizes, able to cut conical holes intended to fit screws of varying head dimensions. A pilot hole is first drilled for the screw Cheap New Orleans Saints Jerseys , followed by countersinking the hole to allow a flathead screw to sit flush with the work surface.
Tiles and glass bits:
Use a carbide-tipped masonry bit (see photo above), push hard and run your drill at about 1,000 rpm. Pull the bit out of the hole occasionally to clear out the powder created by drilling. To make drilling a large hole easier, begin with a small bit and work up: 14 in. to 38 in.
Masonry bits:
The masonry bit shown here is a variation of the twist drill bit. The bulk of the tool is a relatively soft steel and is machined with a mill rather than ground. An insert of tungsten carbide is brazed into the steel to provide the cutting edges.

Masonry bits typically are used with a hammer drill Cheap Saints Jerseys , which hammers the bit into the material being drilled as it rotates; the hammering breaks up the masonry at the drill bit tip, and the rotating flutes carry away the dust
Twist and HSS bits:
The twist drill bit was invented by Steven A. Morse of East Bridgewater, Massachusetts in 1861. Nowadays, the drill bit is usually made by rotating the bar while moving it past a grinding wheel to cut the flutes in the same manner as cutting helical gears. HSS bits are hard and much more resistant to heat than high-carbon steel. They can be used to drill metal Wholesale Rick Leonard Jersey , hardwood, and most other materials at greater cutting speeds than carbon-steel bits and have largely replaced carbon steels.
Multi-purpose bits:
Multi-purpose bits handle thicker metal such as angle iron, as well as sheet metal, aluminum Wholesale Tre'Quan Smith Jersey , masonry, brick, block, tile Wholesale Marcus Davenport Jersey , wood and PVC. They feature steep flutes with ribs for fast dust removal, as well as tips designed to reduce bit-walking for clean holes.
Wood or brad point bits:
Spade bits are used for rough boring in wood. They tend to cause splintering when they emerge from the workpiece. Woodworkers avoid splintering by finishing the hole from the opposite side of the work. Some bits are equipped with long shanks and have a small hole drilled through the flat part, allowing them to be used much like a bell-hanger bit. Intended for high-speed use, they are used with electric hand drills. A Brad Point Drill WILL provide the cleanest Wholesale P.J. Williams Jersey , straightest, and most accurately sized hole in the wood of any reasonably priced tool on the market today. The brad in the center of the point allows accurate positioning when starting a hole even if the hole is not 90 degrees from the surface.
