These high-speed steel chucking reamers come in sizes that fall between standard trade sizes, and their sizes are expressed in decimal inches. Right-hand spiral-flute reamers draw chips up out of the hole and are used for reaming blind holes that do not continue all the way through the workpiece. Spiral-flute reamers leave a smoother finish on the hole than straight-flute reamers. These chucking reamers are made from high-speed steel and have a bright finish that is unaffected when their cutting edges are resharpened. The reamers' straight shank mounts to the chuck of a drill press or similar machining tool.

These high-speed steel chucking reamers come in standard sizes expressed in fractional inches. Fractional inch is the most common trade size used for chucking reamers. Right-hand spiral-flute reamers draw chips up out of the hole and are used for reaming blind holes that do not continue all the way through the workpiece. Spiral-flute reamers leave a smoother finish on the hole than straight-flute reamers. These chucking reamers are made from high-speed steel and have a bright finish that is unaffected when their cutting edges are resharpened. The reamers' straight shank mounts to the chuck of a drill press or similar machining tool.

Metric high-speed steel chucking reamers come in standard sizes expressed in millimeters. Right-hand, spiral-flute reamers draw chips up out of the hole and are used for reaming blind holes that do not continue all the way through the workpiece. They enlarge the hole to an exact size for a precise fit when installing fasteners or other parts. This prevents damage to the reamer and the workpiece. Spiral-flute reamers leave a smoother finish on the hole than straight-flute reamers. These chucking reamers are made from high-speed steel and have a bright finish that is unaffected when their cutting edges are resharpened. The reamers' straight shank mounts to the chuck of a drill press or similar machining tool.

These high-speed steel chucking reamers come in standard letter sizes. The trade letter size for each reamer indicates its compatibility with other tools that have the same trade letter size. Right-hand spiral-flute reamers draw chips up out of the hole and are used for reaming blind holes that do not continue all the way through the workpiece. Spiral-flute reamers leave a smoother finish on the hole than straight-flute reamers. These chucking reamers are made from high-speed steel and have a bright finish that is unaffected when their cutting edges are resharpened. The reamers' straight shank mounts to the chuck of a drill press or similar machining tool.

Wire-size high-speed steel chucking reamers come in standard sizes that correspond to American Wire Gauge (AWG) sizes. This ensures compatibility when inserting a wire of the same wire size into the hole created by the tool. The larger the wire size, the smaller the reamer. Right-hand spiral-flute reamers draw chips up out of the hole and are used for reaming blind holes that do not continue all the way through the workpiece. They enlarge the hole to an exact size for a precise fit when installing fasteners or other parts. This prevents damage to the reamer and the workpiece. Spiral-flute reamers leave a smoother finish on the hole than straight-flute reamers. These chucking reamers are made from high-speed steel and have a bright finish that is unaffected when their cutting edges are resharpened. The reamers' straight shank mounts to the chuck of a drill press or similar machining tool.

Oversized high-speed steel chucking reamers are slightly larger than a standard size. They provide a loose fit for standard-size fasteners and other parts that install in the hole. Right-hand spiral-flute reamers draw chips up out of the hole and are used for reaming blind holes that do not continue all the way through the workpiece. Spiral-flute reamers leave a smoother finish on the hole than straight-flute reamers. These chucking reamers are made from high-speed steel and have a bright finish that is unaffected when their cutting edges are resharpened. The reamers' straight shank mounts to the chuck of a drill press or similar machining tool.

Undersized high-speed steel chucking reamers are slightly smaller than a standard size. This helps ensure a tight fit when inserting a standard-size item in a hole made by the tool. Right-hand spiral-flute reamers draw chips up out of the hole and are used for reaming blind holes that do not continue all the way through the workpiece. Spiral-flute reamers leave a smoother finish on the hole than straight-flute reamers. These chucking reamers are made from high-speed steel and have a bright finish that is unaffected when their cutting edges are resharpened. The reamers' straight shank mounts to the chuck of a drill press or similar machining tool.
