Import 20893 Hand Reamer 0.5 in 5 Flute Left Hand Steel

Product Description

The IMPORT 20893 is a hand reamer designed for precision finishing of drilled holes to exact tolerances. Built from steel with a gold oxide finish for corrosion resistance, this reamer features a 0.5-inch diameter cutting edge and five collared flutes arranged in a left-hand spiral direction. With an overall length of 5.75 inches and a flute length of 3.375 inches, it is sized for controlled, manual reaming operations in metal fabrication, plumbing rough-in, and mechanical assembly work. Licensed tradespeople and machinists use this tool to bring pre-drilled holes to final size with smooth, consistent bore walls.

This hand reamer is suited for manual reaming applications in ferrous and general metal workpieces where a finished bore diameter of 0.5 inches is required. The collared flute design controls chip flow and tool depth during hand-driven operation. Typical use cases include plumbing and HVAC fitting preparation, mechanical assembly, and maintenance work where machine reamers are not practical or available.

Key Features

• 0.5-inch reamer diameter for precise half-inch bore finishing
• Five collared flutes for controlled chip evacuation and consistent surface finish
• Left-hand spiral direction reduces chatter during manual operation
• Steel construction provides durability in metal reaming applications
• Gold oxide finish offers added corrosion resistance during storage and use
• Round shank compatible with standard tap wrenches and brace handles

Compatibility

Designed as an OEM-style hand reamer for manual finishing of 0.5-inch diameter bores in metal workpieces across plumbing, HVAC, and general mechanical applications.

Installation Notes

Hand reamers are installed and operated by machinists, pipefitters, plumbers, and HVAC technicians using a standard tap wrench or adjustable brace. Always de-burr and clean the pilot hole before reaming, and apply cutting fluid to reduce friction and extend tool life. Advance the reamer steadily with consistent rotational pressure and never reverse rotation while the tool is engaged in the bore, as this can damage the cutting edges.
