Bridge & Construction Reamers

The Alvord Polk 650-H left-hand spiral flute construction reamer is a round shank tool made of high-speed steel with no finish or coating, and is most commonly chosen for reaming interrupted cuts in structural steel. Construction reamers are tapered to allow the reamer to enter overlapping and misaligned holes where extremely precise tolerances are not necessary, and have a stop collar for safety and depth control.

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.

There are five flutes for all reamers in this series. Tolerances are +0.005 -0.000 inches for all reamers in the 650-H 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.

Bridge & Construction Reamers

The Union Butterfield 4579 high-speed steel left hand spiral flute bridge reamer is a Morse taper shank tool with a black oxide finish, commonly used for reaming interrupted 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. Spiral construction prevents whole-flute contact with the leading edge in an interrupted cut, as in a keyway. This reduces the possibility of damage to the interruption and to the reamer flute. Left-hand spiral tools are good for use in through holes (extending through the workpiece) because they push chips ahead of the tip of the tool.

High-speed steel (HSS) is a common, general-purpose steel for cutting tools and is compatible with a variety of materials. With no coating or surface treatment, this uncoated tool can be used on a broad range of materials and provide an economical alternative to coated tools. Taper shank tools can be self-holding or self-releasing based on the degree of taper: Small tapers are self-holding within a tool holder, while large tapers are self-releasing and will easily release from the tool holder. The shank end of a Morse taper shank tool is self-holding because friction between the tool and the tool holder prevents slippage. It is tapered to ensure accurate alignment of the tool in the socket of the tool holder. Black oxide improves lubricity, resists corrosion, and will not chip or flake; it also helps to prevent buildup and welding of material on the tool’s cutting edge when it is used on iron and steel.

In the Union Butterfield 4579 series, all reamers have three flutes. Tolerances for all reamers in this series are +0.0100” to -0.0000”.

Reamers are used to finish existing holes. When holes are created using common applications such as drilling or punching, they often have minute imperfections. Their roundness may be flawed, or their diameters may be slightly smaller than required. Reamers are made to exacting tolerances, so they can correct such errors and create precisely round holes with exact dimensions. Reaming is often used before tapping screw threads.

Precision Dormer manufactures cutting tools under the brands Precision Twist, Dormer, and Union Butterfield. The company has locations around the world, and makes tools that meet American National Standards Institute (ANSI), National Aerospace Standard (NAS), and Deutsches Institut für Normung (DIN) standards.

Bridge & Construction Reamers

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.

Alvord Polk 650-H High-Speed Steel Construction Reamer, Left Hand Spiral Flute, Round Shank, Uncoated (Bright). 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. Round shank tools are cylindrical and should be held in a good-quality toolholder in order to prevent the reamer from slipping in high torque applications, which can cause tool freeze, loss of accuracy, and tool damage. Uncoated (bright) tools have no finish or coating. They are a good choice for general purpose applications.

Bridge & Construction Reamers

The Alvord Polk 650-H left-hand spiral flute construction reamer is a round shank tool made of high-speed steel with no finish or coating, and is most commonly chosen for reaming interrupted cuts in structural steel. Construction reamers are tapered to allow the reamer to enter overlapping and misaligned holes where extremely precise tolerances are not necessary, and have a stop collar for safety and depth control.

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.

There are five flutes for all reamers in this series. Tolerances are +0.005 -0.000 inches for all reamers in the 650-H 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.

The Union Butterfield 4600 high-speed steel left-hand spiral flute taper pipe reamer is an uncoated (bright) round shank tool with a square end; its standard size and 3/4" per foot taper make it suitable for reaming holes that are to be tapped with National Pipe Taper (NPT) threading. This tool is often used in a drill press, screw machine or lathe. It can be used with cast iron, steel, brass, and most ferrous and non-ferrous materials. Using a taper reamer prior to tapping with taper taps provides threads of better quality. Taper pipe reamers in this series are recommended for tapping any NPT threading: Dryseal or Military Aeronautical Pipe Thread (ANPT) specification. Spiral flute reamers are useful for interrupted cuts because they prevent whole flute contact with the leading edge of an interrupted cut, as in a keyway. This prevents damage to the interruption and the reamer flute. Also, spiral flute taper pipe reamers are designed for reaming harder materials where additional shear is needed. Left-hand spiral tools are good for use in through holes (extending through the workpiece) because they push chips ahead of the tip of the tool. High-speed steel (HSS) is a general-purpose steel for cutting tools that is compatible with many metalworking materials. It is often lower in price than other cutting tool substrates. Square-end shanks help prevent rotation in the tool holder. Uncoated (bright) tools have no additional surftreatment or coating; they are suitable for general-purpose applications. The number of flutes on a reamer depends on the cutting diameter of the tool. Reamers in this series that are 1/8 and 1/4 in diameter have six flutes, 3/8 and 1/2 in diameter have eight flutes, 3/4 to 1-1/2 in diameter have 10 flutes, and 2 in diameter have 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 diameters may be slightly smaller than required. Reamers are made to exacting tolerances, so they can correct such errors and create precisely round holes with exact dimensions. Reaming is often used before tapping screw threads. Precision manufactures machine tools under the following brands: Precision Twist, Precision Dormer, and Union Butterfield. They have locations around the world, and provide tools adhering to ANSI, NAS, and DIN standards. Model # 1810009 Features: Reams holes to be tapped with National Pipe Taper (NPT) threading Spiral construction protects interrupted cuts by preventing whole-flute contact with the leading edge of the interruption Left-hand spiral design pushes chips ahead of the tool into the hole; useful for through holes High-speed steel is compatible with a variety of materials Round shank with square end helps to minimize rotation in the tool holder

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 627-2 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 627-2 series.

Alvord Polk 650-H High-Speed Steel Construction Reamer, Left Hand Spiral Flute, Round Shank, Uncoated (Bright). 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. Round shank tools are cylindrical and should be held in a good-quality toolholder in order to prevent the reamer from slipping in high torque applications, which can cause tool freeze, loss of accuracy, and tool damage. Uncoated (bright) tools have no finish or coating. They are a good choice for general purpose applications.

Bridge & Construction Reamers

The Alvord Polk 650-H left-hand spiral flute construction reamer is a round shank tool made of high-speed steel with no finish or coating, and is most commonly chosen for reaming interrupted cuts in structural steel. Construction reamers are tapered to allow the reamer to enter overlapping and misaligned holes where extremely precise tolerances are not necessary, and have a stop collar for safety and depth control.

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.

There are five flutes for all reamers in this series. Tolerances are +0.005 -0.000 inches for all reamers in the 650-H 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.
