1-1/16" Spiral Flute Hand Expansion Reamer | HSS | DWRRHDES1-1/16

Industrial precision tooling for bore finishing and hole sizing in metalworking environments. The 1-1/16" Spiral Flute Hand Expansion Reamer is designed to clean up and size bored holes with controlled expansion, delivering concentric bore geometry for precision assemblies and fixtures.

Specs

• Dimensions: Diameter 1-1/16"
• Material grade: High Speed Steel

Features

• Flute geometry: Spiral flute design facilitates swarf evacuation and reduces exit pressure, enabling clean hole finish.
• Hand expansion: Manual operation with consistent radial expansion to target diameter.
• Material compatibility: Reamer designed for use with common metals including steel, aluminum, and cast iron; compatible with cutting fluids or lubrication to extend tool life.
• Concentricity: Maintains true bore axis to minimize runout during finish sizing.
• Wear resistance: High Speed Steel substrate provides durable edge retention for repetitive reaming tasks.
• Applications: Ideal for machine shops, maintenance hubs, fixture fabrication, and precision assembly lines where bore size accuracy is critical.
