Chucking reamers (also known as machine reamers) with a taper shank and spiral flute, conforming to the ANSI B94.2 standard, are rotary cutting tools used to enlarge and precisely finish pre-drilled holes in a variety of materials.Â
The tapered shank is designed to be securely held in the spindle of machine tools like drill presses, lathes, turret lathes, screw machines, and machining centers. This design provides self-holding and accurate alignment.
This design helps efficiently remove chips during the reaming process and can lead to a smoother surface finish and better performance, especially in difficult materials or interrupted cuts.
Used in a wide range of materials including steel, aluminum, cast iron, and other ferrous and non-ferrous materials.
Specifically designed for use in machine tools to achieve precise and smooth holes with tight tolerances.
Used to finish pre-drilled holes to the exact desired diameter and surface finish.
Recommended for reaming harder materials like stainless steel and titanium, especially with carbide versions.
Suitable for applications with interruptions like keyways or cross holes due to the spiral flute design.
 Right-hand spiral flutes are ideal for blind holes as they pull chips away from the bottom of the hole.
