Hertel 72291222 Chucking Reamer 11/32 in Hss 6 Flute

Product Description

The HERTEL 72291222 is a high-speed steel (HSS) chucking reamer designed to produce precise, finished holes in metallic workpieces. With a diameter of 11/32 inch (0.3438 decimal inch), a 1-1/2 inch flute length, and a 4-3/4 inch overall length, this reamer is sized for common light-duty to medium-duty machine shop applications. The straight, two-flute-geometry-free six-flute configuration and right-hand cutting direction deliver clean, accurate bores when run in a drill press, lathe, or CNC machining center. The bright, uncoated finish is standard for general-purpose HSS tooling.

This chucking reamer is suited for production and job-shop environments where hole finishing to tight tolerances is required. The straight-cylindrical shank seats directly into standard drill chucks or collets without modification. It is appropriate for use in ferrous and non-ferrous materials where a smooth, dimensionally accurate bore is needed. Machinists, tool-and-die makers, and maintenance technicians are the typical end users.

Key Features

• 11/32 inch (0.3438 inch) reamer diameter for precise hole sizing
• Six straight flutes for stable, chatter-resistant cutting action
• Right-hand cutting direction compatible with standard spindle rotation
• High-speed steel construction provides good wear resistance across common shop materials
• Bright, uncoated finish suitable for general-purpose reaming
• Straight-cylindrical shank for direct chuck or collet mounting

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with standard drill chucks or collets accepting a straight-cylindrical shank in the 11/32 inch diameter range.

Installation Notes

This reamer is installed by a machinist or tooling technician — secure the straight-cylindrical shank firmly in a drill chuck or collet before operation. Always power down and de-energize the machine spindle completely before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not use this reamer to enlarge a hole beyond its rated diameter range, as doing so risks tool breakage and dimensional inaccuracy.
