Hertel 72018054 Chucking Reamer 0.1805 in Hss 6 Flute

Product Description

The HERTEL 72018054 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to precise tolerances in a wide range of workpiece materials. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer measures 0.1805 inches in diameter with an overall length of 4.5 inches and a flute length of 1.125 inches. The straight-cylindrical shank seats directly in standard drill chucks or collet holders without additional adapters. Six right-hand flutes provide smooth cutting action and efficient chip evacuation during through-hole and blind-hole reaming operations.

This reamer is suited for machine shop, toolroom, and production environments where hole finishing to close diameter tolerances is required. It fits vertical mills, drill presses, lathes, and CNC machining centers equipped with compatible chuck or collet systems. Typical applications include sizing holes in steel, aluminum, brass, and other machinable metals where a hand reamer is impractical or where spindle-driven precision is needed. Machinists and tool-and-die professionals are the primary users of this tool.

Key Features

• 0.1805 inch finished diameter falls within the 0.1500 to 0.1999 inch reamer diameter range
• High-speed steel (HSS) construction provides hardness and wear resistance across common workpiece materials
• Bright, uncoated finish suits general-purpose reaming without coating compatibility concerns
• Six straight flutes deliver consistent cutting action and effective chip clearance
• Right-hand cutting direction compatible with standard spindle rotation on most machine tools
• Straight-cylindrical shank fits standard drill chucks and collet holders without adapters

Compatibility

Designed as an OEM-style chucking reamer for use in drill chucks and collet holders on mills, drill presses, lathes, and CNC machining centers that accept straight-cylindrical shank tooling.

Installation Notes

Chucking reamers are installed and operated by machinists using standard machine tools. Secure the straight-cylindrical shank firmly in a drill chuck or collet holder before beginning the operation, and confirm the spindle rotates in the right-hand direction. Always ream at reduced spindle speeds compared to drilling, using appropriate cutting fluid for the workpiece material, and never rotate a reamer in reverse as this dulls the cutting edges. Inspect the shank for chips or burrs before seating to ensure runout is minimized.
