Hertel 72034366 Chucking Reamer 0.4360 in Hss 6 Flute

Product Description

The HERTEL 72034366 is a straight-flute chucking reamer designed for precision hole finishing in metal and similar materials. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent bore sizing across production and maintenance applications. The reamer measures 0.4360 inches in diameter with a 7-inch overall length and a 1.75-inch flute length. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. Six right-hand cutting flutes provide smooth, even material removal, making this tool suitable for operators requiring tight dimensional tolerances on through or blind holes.

This chucking reamer is used in machine shop, maintenance, and toolroom environments where finish reaming to a precise diameter is required. It fits standard drill press, lathe tailstock, and CNC or manual milling machine setups. Typical applications include reaming drilled holes to close tolerance for pin fits, bushing bores, and dowel locations in ferrous and non-ferrous workpieces. The HSS construction handles a broad range of common shop materials without requiring carbide tooling.

Key Features

• 0.4360-inch reamer diameter for precise finished-hole sizing

• Six straight flutes with right-hand cutting direction for smooth bore finishing
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank compatible with drill chucks and collet holders
• 7-inch overall length with 1.75-inch flute length for controlled reaming depth

Compatibility

Designed as a standard chucking reamer for use in drill press, lathe, and milling machine setups requiring a 0.4360-inch finished bore diameter.

Installation Notes

Chucking reamers are installed and operated by machinists, tool and die makers, or maintenance technicians. Always secure the shank fully in the chuck or collet before operation and confirm the workpiece is clamped or fixtured to prevent movement. Power down the machine completely before changing or inspecting tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and achieve the intended surface finish.
