Hertel 83247007 Chucking Reamer 0.1990 in Solid Carbide

Product Description

The HERTEL 83247007 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. Ground to a reamer diameter of 0.1990 inches (Wire Size 8), it holds a tight tolerance of 0.0000 to 0.0002 inches, making it suitable for work where bore accuracy and surface finish are critical. The straight flute geometry and right-hand cutting direction are well matched to through-holes and shorter blind bores in materials that respond cleanly to carbide tooling. With a 3-inch overall length and a 1-inch flute length, the tool fits standard chucking setups on CNC machining centers, manual mills, and drill presses.

This reamer is intended for production and job-shop environments where consistent bore sizing is required. It is a solid carbide construction with a bright, uncoated finish, making it appropriate for ferrous and non-ferrous materials where coating buildup or chemical reaction is a concern. The straight cylindrical shank seats directly into standard collet chucks or drill chucks without adapters, simplifying tool changes in multi-operation setups. Machinists and toolroom technicians working to close-tolerance prints will find the controlled diameter tolerance essential for press-fit, slip-fit, and locating-pin bore applications.

Key Features

• Solid carbide construction for rigidity and long tool life in precision reaming
• 0.1990 inch diameter, Wire Size 8, with tolerance of 0.0000 to 0.0002 inches
• 4-flute straight flute geometry for clean chip evacuation in through-hole applications
• Right-hand cutting direction, compatible with standard spindle rotation
• Bright, uncoated finish suitable for a broad range of workpiece materials
• Straight cylindrical shank for direct mounting in collet or drill chucks

Compatibility

Designed as an OEM-style precision reamer for use in standard chucking setups on CNC machining centers, manual knee mills, and drill presses equipped with collet chucks or drill chucks accepting a straight cylindrical shank.

Installation Notes

This reamer is installed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool is properly seated and tightened in the chuck before beginning a cut. Use appropriate cutting fluid for the workpiece material to protect tool life and maintain bore finish. Do not use this tool as a drill; always pre-drill or bore the hole to near-final diameter before reaming.
