Hertel 83247148 Chucking Reamer 10.5 Mm Solid Carbide

Product Description

The HERTEL 83247148 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 10.5 mm (0.4134 inch) reamer diameter and a diameter tolerance of 0.0000 to 0.0003 inches, this tool delivers tight, repeatable sizing in bored or drilled holes. The straight-cylindrical shank mounts directly in standard chuck-style toolholders, and the 6-flute straight geometry provides smooth, efficient material removal. With an overall length of 3-1/2 inches and a 1-1/4 inch flute length, it is suited for moderate-depth reaming operations. The bright, uncoated carbide finish is appropriate for a wide range of workpiece materials. This reamer is installed and operated by machinists and tool-and-die professionals in CNC and manual machine environments.

This chucking reamer is used in machine shop and production environments where accurate hole diameter and surface finish are required. Typical applications include finish-reaming pre-drilled or bored holes to H7 or similar tolerance fits for dowel pins, bushings, or press-fit components. The right-hand cutting direction and straight-flute configuration make it well-suited for through-holes and shallow blind-hole applications in ferrous and non-ferrous metals. Its solid carbide construction supports use in rigid setups where dimensional precision and tool life are priorities.

Key Features

• 10.5 mm (0.4134 inch) reamer diameter with tolerance of 0.0000 to 0.0003 inches for precise hole sizing
• 6-flute straight geometry for smooth cutting action and consistent finish
• Solid carbide construction provides rigidity and extended tool life in metalworking applications
• Straight-cylindrical shank compatible with standard chuck-style toolholders
• Bright, uncoated finish suitable for dry cutting or use with standard cutting fluids
• Right-hand cutting direction for conventional machine spindle use

Compatibility

Designed as a standard chucking reamer for use in CNC machining centers, knee mills, drill presses, and manual lathes equipped with chuck-style toolholders accepting a straight-cylindrical shank at the 10.5 mm diameter range.

Installation Notes

This reamer is installed and operated by qualified machinists. Before mounting, ensure the machine spindle and toolholder are clean and free of chips or debris that could affect runout. Secure the straight shank firmly in the chuck to minimize deflection, as excessive runout will degrade diameter tolerance and surface finish. Use appropriate cutting fluid for the workpiece material and never force the reamer into an undersized hole — the pre-drilled or bored hole should leave only a minimal amount of material for the reaming operation.
