Hertel 79889499 Chucking Reamer 0.134 in Solid Carbide

Product Description

The HERTEL 79889499 is a solid carbide chucking reamer designed for precision hole finishing in machine tool applications. With a reamer diameter of 0.134 inches and a diameter tolerance of 0.0000 to 0.0002 inches, it delivers tight, consistent bore sizing required in production and toolroom environments. The 4-flute straight geometry provides stable cutting action on through-holes and blind bores alike. This reamer is installed by machinists and tool-and-die professionals using standard drill chucks or collet holders on lathes, drill presses, and machining centers.

This chucking reamer is suited for light-to-medium material removal when refining a drilled or bored hole to a precise final diameter. The straight-cylindrical shank allows secure clamping in a wide range of standard chucks and tool holders. At 2.5 inches overall length with a 0.75-inch flute length, it is well-proportioned for shallow-to-moderate depth applications in ferrous and non-ferrous materials. The bright, uncoated finish makes it a practical choice where coating buildup tolerance is a concern or where re-sharpening is expected.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding applications
• 0.134-inch reamer diameter with tolerance of 0.0000 to 0.0002 inches for precision bore finishing
• 4-flute straight configuration for stable, consistent cutting action
• Right-hand cutting direction standard for conventional machine tool setups
• Straight-cylindrical shank for direct clamping in drill chucks and collet holders
• Bright, uncoated finish — no coating interference for applications requiring re-sharpening or tight tolerance control

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in standard drill chucks and collet-style tool holders on lathes, drill presses, CNC machining centers, and similar machine tools accepting a straight-cylindrical shank.

Installation Notes

Installation is performed by machinists in accordance with standard machine tool practices. Secure the straight-cylindrical shank fully in a matching chuck or collet before operation, and verify runout is within acceptable limits before cutting. Always power down and lock out the machine spindle before changing or inspecting tooling. Pre-drill or bore the workpiece to within recommended stock-removal allowance before reaming to avoid overloading the flutes.
