Hertel 72018450 Chucking Reamer 0.1845 in Hss Straight Flute

Product Description

The HERTEL 72018450 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled holes to precise tolerances. With a 0.1845-inch cutting diameter and a bright, uncoated HSS body, it delivers consistent hole quality in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks and collets, making it practical for use on drill presses, lathes, and CNC equipment. Six straight flutes provide smooth chip evacuation and a clean finished bore. Right-hand cutting direction is standard for conventional clockwise spindle rotation. Overall length is 4.5 inches with a 1.125-inch flute length.

This reamer is suited for production and maintenance machining applications where hole diameter accuracy and surface finish are critical. It is appropriate for tool rooms, job shops, and maintenance facilities working in the 0.1500 to 0.1999-inch diameter range. Machinists, tool-and-die makers, and maintenance technicians use this reamer after drilling to bring a bore to final dimension and finish. It performs in both manual and CNC-driven setups at controlled feed and speed.

Key Features

• 0.1845-inch cutting diameter falls within the 0.1500 to 0.1999-inch HSS chucking reamer range
• Six straight flutes promote smooth chip flow and consistent surface finish in the bore
• Bright, uncoated HSS construction provides good wear resistance across a range of workpiece materials
• Straight-cylindrical shank fits standard drill chucks and collet holders without adapters
• Right-hand cutting direction compatible with standard clockwise spindle machines
• 4.5-inch overall length provides reach for typical through-hole and blind-hole applications

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with drill chucks or straight-shank collet holders accepting a straight-cylindrical shank in the 0.1500 to 0.1999-inch diameter class.

Installation Notes

Install the reamer into a compatible drill chuck or collet and ensure the shank is fully seated and clamped securely before operation. Power down and lock out the machine spindle before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Always ream at reduced feed and speed compared to drilling; consult published HSS reamer speed and feed tables for the specific material being machined.
