Premium 9/16″ Spiral Flute Hand Expansion Reamer HSS DWRRHDES9/16

Industrial-grade reaming tool designed for precise hole sizing and bore enlargement in mechanical assemblies. The 9/16″ spiral flute hand expansion reamer, constructed from High Speed Steel, delivers controlled material removal with smooth cutting action for metalworking and field service tasks.

Specs

Diameter: 9/16″

Material: High Speed Steel (HSS)

Features

Spiral flute geometry: Promotes efficient chip evacuation and reduces cutting forces during manual reaming, improving bore roundness and surface finish.

Hand operation design: Enables controlled, incremental hole enlargement with repeatable results in field service, fixtures, and jig production.

Wear resistance: HSS composition provides durability for repeated use on steel, cast iron, and related alloys.

Hole-sizing precision: Suitable for aligning dowel-pin seats and achieving tight assembly tolerances through precise bore resizing.

Tool geometry: Relieved flute depth minimizes chatter and dwell during manual reaming, enhancing operator control.
