Product Features

  • Straight flute reamers are recommended for general purpose reaming to make minor enlargements to existing holes with a very precise size and roundness
  • Straight flute reamers are good for use in through or blind holes without interruptions such as keyways (through holes extend through the entire workpiece, while blind holes do not)
  • The end of Morse taper shank tools (held in a toolholder) is tapered to ensure accurate alignment of the tool in its socket and is self-holding (friction between the tool and the tool-holder prevents slippage)
  • 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 625-0 straight flute bridge reamer is a Morse taper shank tool made of high-speed steel with no finish or coating, and is most commonly chosen for reaming uninterrupted cuts in structural steel. Bridge reamers are tapered to allow the reamer to enter overlapping and misaligned holes where extremely precise tolerances are not necessary.

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. Taper shank tools can be self-holding or self-releasing based on the degree of taper – small tapers are self-holding within the toolholder, while large tapers are self-releasing and will easily release from the toolholder. The end of Morse taper shank tools (held in a toolholder) is tapered to ensure accurate alignment of the tool in its socket and is self-holding (friction between the tool and the tool-holder prevents slippage). Morse taper is one of the most widely used standards for self-holding tapers.

For reamers in the 625-0 series with 0.3750 to 0.9375 inches diameter there are five flutes, and for 1.0000 to 1.5000 there are six flutes. Tolerances are +0.0030/+0.0060 inches for all reamers in the 625-0 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.

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.

Size: 9/16"System of Measurement: Inch Verified Purchase
Good quality,

The ream has three sections.

1) The tang end is about 3 7/8" long with a #2 Morse taper with an anti-rotation tab on the end.
2) In the middle is 3" of straight reamer at 1/2 inch
3) The working end is about 2 5/32" long and will pick up a hole as small as 9/32"

As is often the case with Amazon (and which cost two stars) the sloth like fulfillment is a definite minus.
