Hertel 79889226 Chucking Reamer 0.097 in Solid Carbide

Product Description

The HERTEL 79889226 is a solid carbide chucking reamer designed for precision hole finishing in metal and composite workpieces. With a nominal diameter of 0.097 inches and a tight tolerance of 0.0000 to 0.0002 inches, this reamer delivers consistent, accurate finished bore diameters in production and maintenance environments. The straight flute geometry and right-hand cutting direction make it well suited for through-hole reaming in stable, rigid setups. At 2.25 inches overall length with a 0.625-inch flute length, it fits standard drill press, CNC machining center, and lathe chuck applications. Machinists and toolroom technicians are the primary users of this tool.

This chucking reamer is appropriate for small-diameter hole finishing operations in precision machining environments, including job shops, production floors, and MRO toolrooms. The 0.097-inch diameter falls in the 0.0500 to 0.0999 inch decimal range, making it a go-to choice for tight-tolerance small-bore work. It is used wherever a drilled or bored hole requires a clean, accurate final dimension. The straight shank seats securely in standard drill chucks or collets without the need for specialized toolholding.

Key Features

• Solid carbide construction for wear resistance and dimensional stability in hard and abrasive materials
• 0.0000 to 0.0002 inch diameter tolerance for precise finished bore dimensions
• Straight flute geometry provides stability and clean chip formation in through-hole applications
• 4-flute design improves surface finish and tool rigidity at small diameters
• Bright uncoated finish maintains sharp cutting edges without coating buildup at small diameters
• Straight cylindrical shank for direct chuck or collet mounting

Compatibility

Designed as a standard chucking reamer for use in drill presses, CNC machining centers, lathes, and similar machine tool setups capable of accepting a straight cylindrical shank tool in the applicable small-diameter range.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with reaming operations and machine tool safety. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool from the chuck or collet. Use a quality cutting fluid appropriate for the workpiece material to extend tool life and improve bore finish. Avoid hand-reaming applications with this tool, as it is designed for machine use only.
