Hertel 79889333 Chucking Reamer 0.112 in Solid Carbide

Product Description

The HERTEL 79889333 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production environments. With a reamer diameter of 0.112 inches and a tight diameter tolerance of 0.0000 to 0.0002 inches, this tool delivers consistent, accurate bore sizing in a single pass. The straight flute geometry suits through-hole reaming in a wide range of workpiece materials. At 2.25 inches overall length with a 0.625-inch flute length and a straight cylindrical shank, it mounts directly in standard chucks or collets on CNC machining centers, drill presses, and manual lathes. Machinists, tool and die makers, and production operators are the primary users of this type of reamer.

This reamer is suited for finish-reaming small-diameter holes in precision components across aerospace, automotive, medical device, and general metalworking applications. The 0.112-inch diameter falls within the 0.1000 to 0.1499-inch decimal inch range, making it appropriate for close-tolerance dowel pin holes, pivot bores, and other features that require controlled surface finish and size. The bright, uncoated finish allows the carbide substrate to perform across ferrous and non-ferrous materials without coating buildup concerns at small diameters.

Key Features

• Solid carbide construction provides rigidity and wear resistance at small diameters
• Reamer diameter tolerance of 0.0000 to 0.0002 inches supports close-tolerance hole finishing
• 4-flute straight configuration for consistent chip evacuation in through-hole applications
• Right-hand cutting direction compatible with standard spindle rotation
• Bright uncoated finish maintains dimensional integrity without coating thickness variation
• Straight cylindrical shank seats in standard drill chucks and collets without adapters

Compatibility

Designed as an OEM-style replacement or direct-use chucking reamer for machine tool setups requiring a straight-shank reamer in the 0.1000 to 0.1499-inch diameter range.

Installation Notes

This tool is installed by machinists or toolroom personnel in CNC or manual machine tool spindles. Power down and lock out the machine before inserting or removing the reamer from the chuck or collet. Ensure the shank is fully seated and the chuck or collet is properly torqued before operating. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
