Alvord Polk 155-0 High-Speed Steel Taper Pin Reamer, Straight Flute, Round Shank, Uncoated Finish, Size Number: 0

Description

Measurement System:Taper Pin  |  Size:0 The Alvord Polk 155-0 straight flute taper pin reamer is a round shank tool made of high-speed steel with no finish or coating, and is most commonly chosen for reaming holes that are intended to receive taper pins. Taper pins are standardized tapered fasteners with one end having a slightly larger diameter than the other end, in order to easily enter a reamed hole and hold itself through friction; some taper pins have threaded ends to receive nuts. Straight flute reamers are useful for uninterrupted cuts in general purpose applications. These reamers make small, circular, and precise enlargements to through and blind holes. 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. For reamers in the 155-0 series with taper pin size 7/0 to 2/0 there are four flutes, for size 0 to 8 there are six flutes, and for sizes 9 and 10 there are eight flutes. Tolerances for machining this reamer series are +.0030 / +.0060 inches. 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.
