Hertel 72016454 Chucking Reamer 0.1645 in Hss 6 Flute

Product Description

The HERTEL 72016454 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.1645-inch diameter. With a straight-cylindrical shank and six straight flutes in a right-hand cutting direction, this reamer delivers consistent bore sizing and smooth surface finish in a machine tool or drill press setup. It measures 4.5 inches in overall length with a 1.125-inch flute length and weighs 0.15 pounds. The bright, uncoated finish suits general-purpose reaming in steel, cast iron, aluminum, and similar machinable materials. Licensed machinists and tool-and-die technicians are the primary users of this tool class.

This chucking reamer is intended for machine-driven applications where tight hole tolerances are required. It fits standard chuck-style toolholders and is sized within the 0.1500 to 0.1999-inch decimal inch reamer diameter range, making it appropriate for production work, job shop operations, and maintenance machining tasks where repeatable hole sizing is critical. It is sold individually and is suited for both light production runs and one-off precision boring applications in metal fabrication and repair environments.

Key Features

• 0.1645-inch reamer diameter for precise hole finishing within the 0.1500 to 0.1999-inch range
• HSS construction provides durability and re-sharpenability across a broad range of machinable metals
• Six straight flutes for smooth, consistent material removal and bore surface finish
• Right-hand cutting direction compatible with standard machine tool spindle rotation
• Straight-cylindrical shank for secure seating in drill chucks and collet holders
• Bright, uncoated finish suitable for general-purpose shop use without coolant-reactive coatings

Compatibility

Designed as an OEM-style machine reamer for use in drill presses, CNC machining centers, turret lathes, and manual milling machines equipped with a standard chuck or collet toolholder accepting a straight-cylindrical shank.

Installation Notes

This tool is installed by a machinist or toolroom technician into a chuck or collet holder rated for the shank diameter. Always ensure the workpiece is securely fixtured and the machine spindle speed is set appropriately for the material and reamer diameter before beginning the cut. Use of cutting fluid is recommended to extend tool life and improve bore finish. Do not attempt to use a chucking reamer as a hand reamer or apply side-load pressure during operation.
