Hertel 72036684 Chucking Reamer 0.6680 in Hss 8 Flute

Product Description

The HERTEL 72036684 is a straight-flute chucking reamer designed for precision hole finishing in machine shop and production environments. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing of drilled or bored holes to a finished diameter of 0.6680 inches. The straight-cylindrical shank seats securely in standard drill chucks or collet-style toolholders. With an overall length of 9 inches and a flute length of 2.25 inches, this reamer suits setups requiring moderate reach and controlled chip evacuation. Machinists and toolroom technicians use this tool for through-hole and blind-hole reaming operations in ferrous and non-ferrous materials.

This chucking reamer is suited for CNC machining centers, manual mills, lathes, and drill presses where a straight-cylindrical shank is preferred. Typical applications include finishing close-tolerance holes in jigs, fixtures, and precision components. The right-hand cutting direction and 8-flute geometry support smooth surface finishes and dimensional consistency across production runs. It fits within the 0.5000 to 0.6999 inch reamer diameter range, making it a practical selection for shop inventories that cover mid-range bore sizes.

Key Features

• 0.6680 inch finished bore diameter for precise hole sizing
• 8 straight flutes promote smooth cutting action and consistent surface finish
• High-speed steel (HSS) construction supports use across a broad range of workpiece materials
• Bright, uncoated finish allows easy visual inspection of tool condition
• Straight-cylindrical shank compatible with standard chucks and collet holders
• Right-hand cutting direction for conventional machine spindle use

Compatibility

Designed as a standard chucking reamer for use in machine tools accepting a straight-cylindrical shank, suitable for finishing holes in the 0.5000 to 0.6999 inch diameter range.

Installation Notes

Chucking reamers are installed and operated by machinists or toolroom technicians. Secure the straight-cylindrical shank firmly in a precision drill chuck or collet to minimize runout before engaging the workpiece. Power down and lock out the machine spindle before changing or inspecting the reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain dimensional accuracy.
