Hertel 72290265 Chucking Reamer Wire 26 Hss Straight Flute

Product Description

The HERTEL 72290265 is a straight-flute chucking reamer ground to a wire size 26 diameter of 0.1470 inches. Made from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent hole finishing in ferrous and non-ferrous materials. The 4-flute, right-hand cutting geometry provides smooth stock removal and accurate hole sizing. With a 3-inch overall length and a 1-inch flute length, this reamer fits standard drill press and CNC lathe chucks. It is used by machinists and toolroom professionals to bring drilled or bored holes to precise final dimensions with controlled surface finish.

This reamer is suited for small-diameter precision hole finishing operations in machine shops, toolrooms, and production environments. The straight-cylindrical shank allows direct mounting in drill chucks, collets, or floating reamer holders. At 0.1470 inches, wire size 26 falls in the 0.1000 to 0.1499 inch diameter range, making it appropriate for fine-tolerance work on small components such as pins, bushings, and close-fit fastener holes. Right-hand cutting direction matches standard spindle rotation on most machine tools.

Key Features

• Wire size 26 diameter: 0.1470 inches for precise small-hole finishing
• HSS tool material provides wear resistance across a broad range of workpiece materials
• Bright, uncoated finish — no coating buildup to affect close dimensional tolerances
• 4-flute straight geometry for smooth cutting action and accurate sizing
• Right-hand cutting direction compatible with standard machine tool spindle rotation
• Straight-cylindrical shank fits drill chucks, collets, and floating holders

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, CNC machining centers, and manual mills equipped with a drill chuck or collet capable of accepting a straight-cylindrical shank in the 0.1470-inch diameter class.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with reaming operations. Ensure the machine spindle is fully stopped and the workpiece is securely clamped before mounting or removing the reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never force a reamer through an undersized hole — the pre-drilled or bored hole should be within accepted stock allowance for the target diameter before reaming.
