Hertel 72308166 Chucking Reamer Wire Size 16 0.177 in

Product Description

The HERTEL 72308166 is a wire-size chucking reamer manufactured from cobalt steel for use in precision hole-finishing operations. Sized at wire gauge 16, this reamer produces a finished bore of 0.177 inches (decimal inch). The tool measures 4.5 inches in overall length with a 1.125-inch straight flute. A bright, uncoated finish is standard. The straight-cylindrical shank seats directly into a drill chuck or collet holder on a lathe, drill press, or CNC machining center. Right-hand cutting direction suits standard spindle rotation. Cobalt steel construction handles harder workpiece materials and elevated cutting temperatures better than standard high-speed steel.

This reamer is intended for production and maintenance machining environments where wire-gauge-sized holes require close tolerances and smooth finishes. Typical applications include reaming pre-drilled through-holes and blind holes in ferrous and non-ferrous metals, plastics, and composites. The straight flute geometry is well suited to short-chipping materials and through-hole work. Machinists, toolroom technicians, and maintenance mechanics in manufacturing, aerospace, and general machine shop settings are the primary users of this tool.

Key Features

• Wire size 16 diameter: 0.177 inches finished bore
• Cobalt steel construction for improved heat and wear resistance over standard HSS
• Straight flute geometry suited to through-hole reaming and short-chipping materials
• Bright, uncoated finish — no coating buildup to affect bore tolerance
• Straight-cylindrical shank for direct chuck or collet mounting
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as a standard wire-size chucking reamer with a straight-cylindrical shank; fits any drill chuck or collet holder accepting a shank diameter appropriate for wire gauge 16 tooling on lathes, drill presses, and CNC machining centers.

Installation Notes

A licensed or qualified machinist should install and operate this tool. Before mounting, confirm the chuck or collet is clean and undamaged to prevent runout that degrades bore finish. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Pre-drill or bore the hole to within a few thousandths of final diameter before reaming — never use a reamer to remove excessive stock.
