Hertel 72290117 Chucking Reamer Size 11 0.1910 in Hss

Product Description

The HERTEL 72290117 is a straight-flute chucking reamer designed to finish-ream wire size 11 holes to a precise 0.1910 inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this six-flute tool delivers accurate, smooth bores in a wide range of ferrous and non-ferrous workpiece materials. The straight-cylindrical shank seats directly in a drill chuck or collet chuck, making it a straightforward drop-in for any manual or CNC drilling operation requiring tight-tolerance hole finishing. Overall length is 3.5 inches with a flute length of 1.25 inches. Right-hand cutting direction. Intended for machinists, tool-and-die tradespeople, and precision fabrication shops.

This reamer is suited for light-material removal passes on through-holes and blind holes where a wire-gauge diameter in the 0.1500 to 0.1999 inch range is required. Typical applications include precision fixture work, jig-plate boring, and component assembly where hole diameter must meet close tolerances. The six-flute geometry distributes cutting load evenly, reducing chatter and improving surface finish on short-flute finishing passes. Sold individually.

Key Features

• Wire size 11 nominal diameter — 0.1910 inch decimal equivalent
• High-speed steel (HSS) construction for general-purpose cutting performance
• Six straight flutes for even load distribution and smooth bore finish
• Bright, uncoated finish — no coating to add dimensional variance
• Straight-cylindrical shank for direct chuck or collet mounting
• Right-hand cutting direction, standard configuration

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill press, lathe tailstock, or CNC spindle setups accepting a straight-cylindrical shank in the 0.1910 inch diameter class. No specific machine model compatibility was stated by the manufacturer for this part number.

Installation Notes

Chucking reamers are installed by licensed machinists or experienced toolroom personnel. Secure the straight-cylindrical shank firmly in a drill chuck or precision collet before use, and verify runout with an indicator before cutting. Always apply cutting fluid appropriate to the workpiece material to extend tool life and improve surface finish. Do not use a chucking reamer as a drill — it is a finishing tool only and must follow a drilled or bored hole undersized by the appropriate stock allowance.
