Hertel 2329159 Hand Reamer 1-3/16 in Hss 10 Flute

Product Description

The HERTEL 2329159 is a straight-flute hand reamer designed for precision finishing and sizing of drilled holes in metal workpieces. Built from high speed steel (HSS) with a bright uncoated finish, this reamer delivers clean, accurate bores in a range of ferrous and non-ferrous materials. It features a 1-3/16 inch (1.1875 inch decimal) cutting diameter, a 6 inch flute length, and a 12 inch overall length, giving machinists and toolroom technicians the reach and cutting surface needed for through-hole finishing in medium to heavy stock. The straight shank allows direct mounting in standard hand or machine reamer holders.

This reamer is suited for hand reaming operations on machine tool setups, manual drill press work, and bench-mounted applications where precise hole tolerance and surface finish are required. With 10 straight flutes and a right-hand cutting direction, it produces smooth, consistent bore walls. It is a common choice for toolroom, maintenance, and production environments where hole sizing to close tolerances is a routine requirement.

Key Features

• 1-3/16 inch (1.1875 inch) cutting diameter for precise bore sizing
• High speed steel construction for durability across ferrous and non-ferrous materials
• 10 straight flutes for smooth, consistent material removal
• 6 inch flute length provides extended cutting surface contact
• 12 inch overall length accommodates deeper through-hole applications
• Bright uncoated finish suitable for general-purpose reaming without coating-related clearance concerns
• Right-hand cut with straight shank for compatibility with standard reamer drivers and holders

Compatibility

Designed as a general-purpose hand reamer for use in standard straight-shank reamer holders and manual or machine-driven reaming applications requiring a 1-3/16 inch finished bore diameter.

Installation Notes

This tool is installed and operated by machinists, toolroom technicians, and maintenance professionals. Before use, ensure the workpiece is securely fixtured and the reamer is properly aligned with the pilot hole to prevent chatter or bell-mouthing. Apply appropriate cutting fluid for the workpiece material to improve surface finish and extend tool life. Never force a reamer through an undersized hole — the pilot bore should be drilled to the correct pre-ream diameter before using this tool.
