Hertel 72026156 Chucking Reamer 0.2615 in Hss 6 Flute

Product Description

The HERTEL 72026156 is a straight-flute high-speed steel (HSS) chucking reamer designed for precision hole finishing in machining operations. With a reamer diameter of 0.2615 inches, a 6-inch overall length (OAL), and a 1.5-inch flute length, this tool delivers accurate, repeatable bore sizing on ferrous and non-ferrous workpieces. The straight-cylindrical shank allows direct mounting in drill chucks, collet chucks, or machine tool holders. The bright uncoated finish is suited for general-purpose reaming where coolant or cutting oil is applied at the spindle. Right-hand cutting direction is standard for conventional machine tool setups.

This chucking reamer is used in manual or CNC machining centers, drill presses, and lathes for finish-reaming drilled or bored holes to close tolerances. Typical applications include fixture and jig work, bearing seat preparation, and precision through-hole finishing in production or job-shop environments. The 6-flute geometry provides a smooth surface finish and stable cutting action at moderate feed rates. Machinists, tool-and-die makers, and CNC operators working in metal fabrication, aerospace, or general manufacturing will encounter this tool class regularly.

Key Features

• 0.2615 inch reamer diameter for precise hole finishing in the 0.2500 to 0.2999 inch range
• High-speed steel (HSS) construction for toughness and regrindability
• 6-flute straight geometry for smooth surface finish and even chip distribution
• Bright uncoated finish suitable for use with cutting oils and general-purpose coolants
• Straight-cylindrical shank for compatibility with standard drill chucks and collet holders
• Right-hand cutting direction matches conventional machine tool spindle rotation

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks, ER collet chucks, and straight-shank tool holders on drill presses, CNC machining centers, and lathes.

Installation Notes

Installation is performed by machinists or CNC operators familiar with rotating cutting tool setup. Secure the shank fully in the chuck or collet holder and verify runout before cutting. Always apply appropriate cutting fluid for the workpiece material to extend tool life and achieve finish tolerances. Power down and lock out the machine spindle before changing or inspecting the reamer.
