Hertel 72013659 Chucking Reamer 0.1365in Hss Straight Flute

Product Description

The HERTEL 72013659 is a straight-flute chucking reamer designed to finish-ream drilled holes to precise tolerances in metalworking applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer features 4 flutes cutting in the right-hand direction. It measures 4 inches in overall length with a 1-inch flute length and a nominal reamer diameter of 0.1365 inches. The straight-cylindrical shank allows secure mounting in standard drill chucks, collets, or machine tool holders. It is suited for use in drill presses, lathes, and CNC machining centers where hole quality and dimensional accuracy are the priority.

This chucking reamer is used in general machining shops, toolrooms, and production environments where small-diameter holes require a clean, accurate finish. The 0.1365-inch diameter falls within the 0.1000 to 0.1499 inch reamer diameter range, making it appropriate for finish-reaming holes in steel, aluminum, cast iron, and similar workpiece materials. Machinists and tool-and-die technicians are the primary installers. It is a standard, non-dowel-pin and non-over/under-size reamer, suited to nominal hole finishing without offset correction.

Key Features

• 0.1365-inch nominal reamer diameter for precise small-diameter hole finishing
• HSS construction provides toughness and wear resistance across common workpiece materials
• Bright, uncoated finish — ready to run as-is or accept aftermarket coating
• 4 straight flutes with right-hand cutting direction for conventional reaming operations
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• 4-inch overall length with 1-inch flute length suits bench and machine tool setups

Compatibility

Designed as a standard chucking reamer for use in any machine tool that accepts a straight-cylindrical shank tool with a nominal diameter in the 0.1000 to 0.1499 inch range, including drill presses, lathes, and machining centers.

Installation Notes

Installation is performed by qualified machinists or tool-and-die technicians. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer. Secure the straight-cylindrical shank firmly in the chuck or collet to minimize runout, which directly affects hole quality and tool life. Apply appropriate cutting fluid for the workpiece material to reduce heat buildup and extend reamer life.
