Best reamer chucking
1. Union Butterfield 4535 High-Speed Steel Chucking Reamer, Right Hand Spiral Flute, Round Shank, Uncoated (Bright), 1/2 inch
Feature
Spiral construction protects interrupted cuts by preventing whole-flute contact with the leading edge of the interruptionRight-hand spiral pulls chips away from the tip of the tool to prevent clogging in blind holes
High-speed steel is compatible with a variety of materials
Uncoated (bright) tools have no additional surface treatment or coating for use on a broad range of materials
45-degree bevel at the cutting tip facilitates entry to pre-drilled holes
Description
The Union Butterfield 4535 uncoated high-speed steel right-hand spiral flute chucking reamer (also called a machine reamer) is a round shank tool with a 45-degree bevel lead, commonly used for general purpose reaming; it is also chosen for reaming interrupted cuts and blind holes (with only one opening). This tool is often used in a drill press, screw machine, or lathe. Right-hand spiral reamers are useful for interrupted cuts and blind holes (with only one opening). 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. Right-hand spiral tools pull chips away from the tip of the tool, instead of driving chips in front of the tool. As a result right-hand spiral reamers are useful when reaming blind holes, since pulling chips out of the hole prevents clogging as well as tool damage that can result from clogging.
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. Round shank allows the reamer to be used with a variety of tool-holding systems. Like most non-tapered chucking reamers, this tool has a 45-degree bevel at the cutting tip that facilitates entry to pre-drilled holes.
In the Union Butterfield 4535 series, reamers 0.0625 to 0.1410 in diameter have four flutes, 0.1562 to 0.5312 in diameter have six flutes, and 0.5625 to 1.5000 in diameter have eight flutes. Tolerances for reamers up to 0.5000 are +0.0002 to -0.0000; larger than 0.0500 and up to 0.7500 are +0.0003 to -0.0000; and larger than 0.7500 up to 1.5000 are +0.0004 to -0.0000. There is an exception for reamers that are dowel-pin sized; their tolerances are +0.0000 to -0.0002.
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.

2. Alvord Polk 127-1 High-Speed Steel Chucking Reamer, Right Hand Spiral Flute, Round Shank, Uncoated Finish, Size: G
Feature
Right-hand spiral reamers are good for use in blind holes (holes that do not extend all the way through a workpiece), as they pull chips up and out of the holeSpiral flute 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
(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
Description
The Alvord Polk 127-1 right-hand spiral chucking reamer (also called a machine reamer) is a general purpose round shank tool made of high-speed steel with no finish or coating, and is most commonly chosen for reaming interrupted cuts. This tool can be used in a drill press, screw machine, lathe, or other good-quality toolholder.
Right-hand spiral reamers are useful for interrupted cuts and in blind 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 the reamer flute. Right-hand spiral style tools also pull chips away from the tip of the tool, instead of driving chips in front of the tool. Right-hand spiral reamers are also useful when reaming blind holes, since pulling chips out of the hole prevents clogging, which may cause tool damage.
For reamers in the 127-1 series with 0.0280 0.1561 inches diameter there are four flutes, for 0.1562 0.5220 inches diameter there are six flutes, for 0.5221 0.8820 inches diameter there are eight flutes, for 0.8821 1.1950 inches diameter there are 10 flutes, and for 1.1951 1.5000 inches diameter, there are 12 flutes. Tolerances are +0.0002 -0.0000 inches for all reamers in the 127-1 series except for those that are dowel-pin sized, in which case tolerances are +0.0000 -0.0002 inches.
Reamers are used to finish existing holes. When holes are created using common applications like drilling or punching they often have minute imperfections.

Alvord Polk 128-0 Cobalt Steel Chucking Reamer, Straight Flute, Round Shank, Uncoated Finish, Size: #1
Feature
Straight flute reamers are recommended for general purpose reaming to make minor enlargements to existing holes with a very precise size and roundnessStraight 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)
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
Cobalt steel is used for tough machining applications and on materials such as cast iron, cast steel and heat-treated steel. Cobalt steel resists abrasion and high cutting temperatures and has higher feed rates compared to high-speed steel
Description
The Alvord Polk 128-0 straight flute chucking reamer (also called a machine reamer) is a general purpose round shank tool made of cobalt steel with no finish or coating, and is most commonly chosen for reaming in high-temperatures generated by machining tough, hard materials applications, or with abrasive materials. Cobalt steel tools are good for machining stainless steel and nickel alloys, which are harder and generate more heat through friction, giving cobalt a longer-lasting sharp edge than an equivalent high-speed steel tool. This tool can be used in a drill press, screw machine, lathe, or other good-quality toolholder.
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. Cobalt steel is commonly chosen to make tools with exceptional wear resistance and temperature stability, and can be fed at higher rates than high-speed steel, while being more economical than carbide.
For reamers in the 128-0 series with 0.0280 0.1561 inches diameter there are four flutes, for 0.1562 0.5220 inches diameter there are six flutes, for 0.5221 0.8820 inches diameter there are eight flutes, for 0.8821 1.1950 inches diameter there are 10 flutes, and for 1.1951 1.5000 inches diameter, there are 12 flutes. Tolerances are +0.0002 -0.0000 inches for all reamers in the 128-0 series except for those that are dowel-pin sized, in which case tolerances are +0.0000 -0.0002 inches.
Reamers are used to finish an existing hole. These holes are often adequate, but in some engineering applications the resulting hole is not round enough or is incorrectly sized, and therefore reaming is necessary. Reaming positively affects the mechanical properties of the hole by producing a hole with an exceptionally smooth finish and precise roundness and diameter. Reaming is often used before tapping screw threads.
