Product Features

  • Left-hand spiral reamers are good for use in through holes (holes that extend all the way through a workpiece), as they push chips ahead of the tool and into the hole
  • Spiral reamers are recommended for reaming holes with interruptions, as they prevent damage to the workpiece edge and tool
  • Hand reamers fit into a tap wrench, adjustable hand wrench, or standard tap/reamer chucks
  • Uncoated (bright) tools have no finish or coating. They are a good choice for general purpose applications
  • High-speed steel is a common general purpose steel for cutting tools, is compatible with a variety of materials, and tends to be lower in price than cobalt steel or carbide

Product Description

The Alvord Polk 101-2 left-hand spiral flute reamer is tool made of high-speed steel with no finish or coating, and is most commonly chosen for reaming interrupted cuts by hand.

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 also useful when reaming 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. Right-hand cut tools rotate counterclockwise as they cut, when viewed facing the tip of the tool. Hand reamers have a different shank type than other reamers – the shank itself is round, but the end opposite the tip has a squared-off profile for a short length of the shank, which allows the reamer to fit into a tap wrench, adjustable hand wrench, or standard tap/reamer chucks. The unique curved profile at the tip is meant to allow the reamer to enter a hole and center itself.

For reamers in the 101-2 series with 0.1250 – 0.5312 inches diameter there are six flutes, for 0.5512 – 1.1250 inches diameter there are eight flutes, and for 1.1875 – 1.5000 inches diameter, there are 10 flutes. Tolerances are +0.0001/+0.0004 inches for reamers in the 101-2 series with diameters of 0.1250 to 0.2500 inches, +0.001/+0.005 inches for diameters of 0.2656 to 1.0000 inches, and +0.002/+0.006 for diameters of 1.0625 to 1.5000 inches in the 101-2 series.

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.
