Hertel 79890562 Chucking Reamer Wire 19 0.1660 in Solid Carbide

Product Description

The HERTEL 79890562 is a solid carbide chucking reamer in wire gauge size 19, ground to a decimal diameter of 0.1660 inches with a tolerance of 0.0000 to 0.0002 inches. It features a straight flute geometry and a straight cylindrical shank designed for use in standard drill chucks and collet holders. With an overall length of 2.75 inches and a flute length of 0.875 inches, this reamer is suited for finishing holes to close tolerances in a compact workpiece profile. The bright, uncoated solid carbide construction provides rigidity and edge retention in demanding materials. Licensed machinists and tool-and-die technicians are the primary users of this tool in production and job-shop environments.

This chucking reamer is used to bring drilled or bored holes to a precise final diameter in ferrous and non-ferrous metals, plastics, and composites. Its 4-flute, right-hand cutting configuration delivers a smooth finish in through-holes and blind holes at wire gauge size 19. The compact flute length makes it appropriate for shallow finishing passes in tight setups on CNC machining centers, turret lathes, and drill presses where a short-reach reamer is required.

Key Features

• Wire gauge size 19, decimal diameter 0.1660 inches with a tight tolerance of 0.0000 to 0.0002 inches
• Solid carbide construction for rigidity and wear resistance in close-tolerance finishing work
• Straight flute design suited for through-hole and short blind-hole reaming
• 4 flutes provide stable cutting action and consistent surface finish
• Bright uncoated finish — ready to use without additional prep on most work materials
• Right-hand cut with straight cylindrical shank for direct chuck or collet mounting

Compatibility

Designed as a standard chucking reamer for use in drill chucks and collet holders that accept a straight cylindrical shank at wire gauge size 19 (0.1660 inches). Verify spindle chuck capacity and machine RPM range before installation.

Installation Notes

This tool is installed by machinists in machine tools including CNC machining centers, drill presses, and lathes. Secure the straight shank firmly in a drill chuck or collet before running the spindle. Always bring the workpiece hole to the correct pre-ream diameter before using a reamer — using a reamer to remove excess stock will damage the cutting edges. Power down the machine and lock out the spindle before changing or inspecting the tool.
