1-5/16" Spiral Flute Chucking Reamer | HSS | DWRRSP1-5/16

Industrial machining tooling category for precision bore finishing in high production environments.

The 1-5/16 inch spiral flute chucking reamer in High Speed Steel delivers consistent hole geometry and dependable wear performance on CNC and manual machines.

Diameter: 1-5/16 inch; Material: High Speed Steel; Flute geometry: Spiral; Product type: Chucking reamer; Usage: Hole finishing in metalworking applications.

In operation, spiral flute reamers provide improved chip evacuation and smoother bore surfaces. The design concentrates cutting action along the flute, reducing rubbing on the bore walls and extending tool life when reaming through common industrial metals such as carbon steel, alloy steel, stainless steel, cast iron, and selected nonferrous alloys.

Use cases: CNC milling centers, manual mills, drill presses, and other machine tools performing precision finishing operations on predrilled bores. The 1-5/16 inch diameter is common for mid range bore sizes, offering tight tolerance control and consistent surface finish across production runs.

Benefits: Concentric bore maintenance due to rigid chucking format; Reduced burr formation due to sharp cutting edge; Chip evacuation provided by spiral flute; Tool life improvement due to robust High Speed Steel composition.

Compatibility and handling: Compatible with standard chucking tools, collets, and portable reaming fixtures used on industrial machine tools; requires appropriate lubrication and proper pecking to avoid chatter; maintain cutting fluids to prevent material build-up; ensure proper alignment to avoid deflection.
