Hertel 72017056 Chucking Reamer 0.1705 in Hss 6 Flute

Product Description

The HERTEL 72017056 is a straight-flute chucking reamer designed to finish-ream drilled holes to a precise 0.1705-inch diameter. Machined from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing in ferrous and non-ferrous materials across standard CNC and manual lathe or drill press setups. The straight-cylindrical shank seats securely in a drill chuck or collet, and the 6-flute geometry distributes cutting load evenly for smooth, accurate bore finishes. Overall length is 4.5 inches with a flute length of 1.125 inches. This tool is intended for machinists, tool-and-die technicians, and maintenance professionals requiring close-tolerance hole finishing.

This chucking reamer is suited for light production and maintenance machining applications where a drilled hole must be brought to a precise finish diameter. It is appropriate for use in manual drill presses, lathes, and CNC machining centers with appropriate chuck or collet toolholding. The 0.1705-inch diameter falls within the 0.1500 to 0.1999-inch decimal-inch range, making it a standard choice for small-bore finishing work in general metalworking and repair shops. Right-hand cutting direction is standard for conventional machine spindle rotation.

Key Features

• 0.1705-inch finished bore diameter for close-tolerance reaming applications
• High-speed steel (HSS) construction provides durability across a range of workpiece materials
• 6-flute straight design distributes cutting forces evenly for improved surface finish
• Bright, uncoated finish suitable for general-purpose use without coating-related dimensional offset
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Right-hand cutting direction matches conventional machine spindle rotation

Compatibility

Designed as an OEM-style chucking reamer for use in drill presses, lathes, and machining centers equipped with standard drill chucks or collets accepting a straight-cylindrical shank in the 0.1500 to 0.1999-inch diameter range.

Installation Notes

Installation and use should be performed by qualified machinists following applicable shop safety procedures. Secure the straight-cylindrical shank firmly in a drill chuck or collet before operation and verify spindle runout is within acceptable limits to maintain bore accuracy. Always bring the machine to a complete stop before changing or adjusting tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish quality.
