Hertel 79889598 Chucking Reamer 0.1460 in Solid Carbide

Product Description

The HERTEL 79889598 is a solid carbide chucking reamer designed for precision hole finishing in machining applications. With a nominal diameter of 0.1460 inches and a diameter tolerance of 0.0000 to 0.0002 inches, it holds tight dimensional control for close-tolerance bores. The four straight flutes and right-hand cutting direction provide smooth, consistent stock removal. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. At 2.5 inches overall length with a 0.75-inch flute length, it is suited to shallow finishing passes in small-diameter holes. Machinists and tool-and-die professionals rely on this style of reamer where bore finish and size consistency are critical.

This chucking reamer is used in production and job-shop machining environments where holes require precise sizing after drilling. It is appropriate for ferrous and non-ferrous materials where a solid carbide cutting edge provides the rigidity and wear resistance needed to maintain tolerance across a run. Typical applications include fixture bores, close-fit pin holes, and precision housings in both manual and CNC machine setups. The bright, uncoated finish means the cutting geometry is ready to run as delivered without additional preparation.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision boring
• Diameter tolerance of 0.0000 to 0.0002 inches for close-tolerance hole sizing
• Four straight flutes with right-hand cutting direction for smooth stock removal
• Straight-cylindrical shank for compatibility with standard chucks and collets
• Bright, uncoated finish — no additional prep required before use
• Compact 2.5-inch overall length suited to shallow finishing applications

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in standard drill chucks and collet-style toolholders accepting a straight-cylindrical shank at the 0.1460-inch diameter range.

Installation Notes

Chucking reamers are installed and operated by machinists on manual mills, lathes, or CNC machining centers. Ensure the workpiece is securely fixtured and the spindle is fully stopped before loading or removing the tool from the holder. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Inspect the shank seating and runout before commencing the finishing pass to avoid oversizing the bore.
