Alvord Polk 00063 Chucking Reamer Size 26 Hss

Product Description

The ALVORD POLK 00063 is a straight-flute, right-hand chucking reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel (HSS) with a bright uncoated finish, it delivers accurate sizing at a reamer diameter of 0.1470 inches (Wire Size 26) with a tolerance of +0.0002 to 0.0000 inches. The straight-cylindrical shank seats securely in standard drill press or milling machine chucks. At 4 inches overall length with a 1-inch flute length and 4-flute geometry, this tool is suited for machinists and tool-and-die professionals who need repeatable, close-tolerance results in production or maintenance environments.

This reamer is used in machine shop and maintenance-repair-operations (MRO) settings where hole diameter accuracy is critical. The 0.1470-inch diameter corresponds to Wire Size 26, making it appropriate for finishing drilled holes to tight tolerances in steel, aluminum, brass, and similar machinable materials. The straight-flute design is well suited for through-holes and short blind holes where chip evacuation is manageable. It belongs to ALVORD POLK Series 897-A-S and is sold individually.

Key Features

• Reamer diameter: 0.1470 inches (Wire Size 26) with tolerance of +0.0002 to 0.0000 inches
• High-speed steel (HSS) construction for durability across a range of machinable metals
• Straight-cylindrical shank for direct chuck mounting on drill presses and milling machines
• 4-flute, straight-flute geometry with right-hand cutting direction
• Bright uncoated finish - no coating to affect dimensional accuracy on close-tolerance work
• 4 inches overall length, 1-inch flute length - compact profile for general machine reaming

Compatibility

Designed as an OEM-style precision reamer for use in standard chucking setups on drill presses, lathes, and milling machines accepting a straight-cylindrical shank in the applicable diameter range.

Installation Notes

Chucking reamers are installed and operated by machinists or qualified tool-and-die technicians. Power down and de-energize the machine completely before mounting or removing the tool from the chuck. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Do not use a chucking reamer to remove excessive stock - pre-drill the hole to within a few thousandths of final size before reaming.
