High Quality 9/32″ Straight Flute Hand Expansion Reamer HSS DWRRHDE9/32

The 9/32 inch Straight Flute Hand Expansion Reamer is a precision cutting tool designed for manual hole finishing in industrial metalworking environments. It enables controlled enlargement of drilled holes with a smooth surface finish to tight tolerance in ferrous and nonferrous alloys.

Specs

Diameter: 9/32 inch

Drive type: Hand

Material grade: High Speed Steel

Features

Application: Hand expansion reaming for precise enlargement of predrilled holes, delivering consistent diameter with minimal deviation in manual operations.

Straight flute design: Promotes a true reaming path, reduces wandering, and yields concentric hole geometry for reliable assembly fits.

Material: High Speed Steel substrate provides wear resistance and edge retention across common metalworking alloys used in industrial settings.

Finish and surface quality: Produces a smoother hole exit compared to drilling alone, improving subsequent fastener seating and component alignment.

Compatibility: Suitable for use with standard hand reaming practice and compatible fixtures for manual or light-duty machine reaming operations.

Maintenance: Keep edge sharp; use appropriate cutting fluid to reduce heat and extend service life in repeated use scenarios.
