Hertel 2291383 Chucking Reamer Wire 38 0.1015 in Hss

Product Description

The HERTEL 2291383 is a high-speed steel (HSS) chucking reamer sized to wire gauge number 38, producing a finished bore diameter of 0.1015 inches. Designed for precision hole finishing, this reamer removes minimal stock to bring a drilled or bored hole to a tight, accurate tolerance. The straight flute geometry suits through-hole and general-purpose reaming in a wide range of metals and plastics. At 3.5 inches overall length with a 0.875 inch flute length, it fits standard drill chucks and collet holders with a straight-cylindrical shank. Machinists and toolroom operators use this style of reamer on manual mills, lathes, and drill presses where consistent bore finish and diameter accuracy are critical.

This chucking reamer is suited for general machine shop and production environments requiring small-diameter precision reaming in the 0.1000 to 0.1499 inch range. Wire-gauge reamers in this size class are commonly used in instrument manufacturing, tooling fabrication, and light mechanical assembly where close-tolerance holes are needed for pins, fasteners, or locating features. The straight-cylindrical shank allows direct mounting in standard drill chucks, collet chucks, and floating reamer holders on CNC and manual machine tools.

Key Features

• Wire size 38 reamer diameter of 0.1015 inches for precision bore finishing
• HSS tool material provides wear resistance across a broad range of workpiece materials
• Straight flute design suitable for through-hole reaming and general-purpose applications
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• 3.5 inch overall length with 0.875 inch flute length for compact rigidity in small-diameter work

Compatibility

Designed as an OEM-style replacement or direct-use chucking reamer for machine tools accepting a straight-cylindrical shank in the small-diameter wire-gauge size range.

Installation Notes

Chucking reamers are installed by qualified machinists following standard machine tool setup procedures. Ensure the machine spindle and chuck are fully stopped and locked before mounting or removing the reamer. Use a properly sized collet or drill chuck that matches the straight-cylindrical shank diameter to prevent runout. Apply appropriate cutting fluid for the workpiece material to extend tool life and achieve the best bore finish.
