Specs

Diameter: 3/4 inch

Material grade: High Speed Steel

Features

Spiral flute geometry: facilitates efficient chip evacuation and provides a stable cutting path during manual reaming, reducing dwell and chatter.

Hand expansion capability: enables incremental hole enlargement to final size with repeatable tolerance, supporting precise fits for pins and bushings.

Cutting material: High Speed Steel for wear resistance and extended tool life when reaming metallic workpieces such as steel and cast iron.

Finish quality: produces a smooth bore surface suitable for precision assemblies when used with proper drill sizing and alignment.

Applications: ideal for pre-drilled holes in gear housings, bearing housings, valve bodies, and alignment holes for mechanical assemblies in machine shops and maintenance operations.

Usage guidance: operate with steady, perpendicular feed to maintain hole circularity and final size accuracy during manual reaming.
