About Alvord Polk 207-2 High-Speed Steel Taper Pipe
The Alvord Polk 207-2 left-hand spiral flute taper pipe reamer is tool made of high-speed steel with no finish or coating, and is most commonly chosen for reaming holes that meet the standard for pipes and holes that will be tapped with American National Standard Taper Pipe threading. Left-hand spiral reamers are useful for interrupted cuts and in through holes. Spiral reamers prevent whole flute contact with the leading edge in an interrupted cut, as in a keyway. This prevents damage to the interruption and reamer flute. Left-hand spiral style tools also push chips ahead of the tip of the tool, instead of pulling chips out of a hole. Left-hand spiral reamers are commonly used in through holes, since pushing chips into the hole can cause clogging, which may damage the tool. High-speed steel is a general purpose steel for cutting tools and is compatible with many metalworking materials. It is often lower in price than other cutting tool materials. Square shanks prevent tool rotation in the toolholder. For reamers in the 207-2 series with taper numbers 1/8 to 1/2 there are six flutes, for taper number 3/4 there are eight flutes, for taper numbers 1 to 1-1/2 there are 10 flutes, and for taper number 2 there are 12 flutes. Reamers are used to finish existing holes. When holes are created using common applications like drilling or punching they often have minute imperfections. Their roundness may be flawed, or their diameter may be slightly smaller than required. Reamers are made to exacting tolerances, so they can correct such errors and create precisely round holes of exacting dimensions. Reaming is often used before tapping screw threads. Alvord Polk manufactures a broad family of cutting tools, brushes, and tooling components, following ISO 9001 standards for quality and environmental impact of their products. Their offices and manufacturing facilities have been located in the United States since 1881.
