Hertel 79888921 Chucking Reamer 0.056in Solid Carbide

Product Description

The HERTEL 79888921 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance machining applications. With a reamer diameter of 0.056 inches and a diameter tolerance of 0.0000 to 0.0002 inches, this tool delivers accurate, repeatable results in production and job-shop environments. The straight flute geometry suits reaming in a wide range of materials, and the bright uncoated finish is standard for solid carbide tooling of this type. Overall length is 1.5 inches with a flute length of 0.375 inches. This reamer is suited for machinists and tool-and-die professionals working on close-tolerance bores in small-diameter applications.

This chucking reamer is intended for use in CNC machining centers, drill presses, and manual lathes or mills where a straight-cylindrical shank is compatible with standard chucks and collets. The 4-flute straight flute configuration makes it appropriate for through-hole and blind-hole reaming in ferrous and non-ferrous materials. Its small diameter targets micro-bore finishing work common in precision instrument, medical device, and aerospace component manufacturing environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• 0.056 inches reamer diameter with a tight tolerance of 0.0000 to 0.0002 inches for accurate bore sizing
• 4-flute straight flute design for consistent chip evacuation and surface finish
• Straight-cylindrical shank compatible with standard chucks and collets
• Right-hand cutting direction for conventional clockwise spindle operation
• Bright uncoated finish suitable for a broad range of workpiece materials

Compatibility

Designed as an OEM-style chucking reamer for use in any machine tool accepting a straight-cylindrical shank in the applicable diameter range.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist familiar with proper tool-holding and speeds-and-feeds selection for solid carbide tooling. Secure the straight shank firmly in a precision collet or drill chuck before operation to minimize runout. Always power down and lock out the machine spindle before changing or inspecting tooling. Do not use this reamer as a drill; it is designed exclusively for finishing pre-drilled or bored holes.
