Hertel 79890497 Chucking Reamer Wire 11 Solid Carbide

Product Description

The HERTEL 79890497 is a solid carbide chucking reamer designed to finish-ream precision holes to a wire size 11 diameter of 0.1910 inches. Built with a straight flute geometry and a straight cylindrical shank, this reamer delivers consistent, repeatable bore finishing in ferrous and non-ferrous materials. The bright, uncoated carbide construction offers rigidity and dimensional accuracy well-suited to close-tolerance work. With a diameter tolerance of 0.0000 to 0.0002 inches, the 79890497 holds tight limits expected in toolroom, production machining, and maintenance environments. Four flutes distribute cutting load evenly across the bore, reducing chatter and improving surface finish. Overall length is 2.75 inches with a flute length of 0.875 inches.

This reamer is used in drill press, lathe, or CNC machining center applications where a wire size 11 reamed hole is required. Typical applications include fixture and jig work, close-tolerance bearing and bushing bores, and precision alignment pin holes in fabrication or maintenance settings. The straight shank seats directly into standard drill chucks or collets without an adapter. Right-hand cutting direction makes it compatible with conventional clockwise spindle rotation.

Key Features

• Wire size 11 diameter: 0.1910 inches with a tolerance of 0.0000 to 0.0002 inches
• Solid carbide construction for rigidity and wear resistance in demanding bore-finishing applications
• Straight flute design with 4 flutes for even load distribution and clean surface finish
• Bright, uncoated finish suitable for a broad range of workpiece materials
• Straight cylindrical shank for direct chuck or collet mounting
• Right-hand cut matches standard spindle rotation on drill presses, lathes, and machining centers

Compatibility

Designed as an OEM-style chucking reamer for use in any machine spindle accepting a straight cylindrical shank in the corresponding diameter range; no specific model compatibility data was provided in the source information.

Installation Notes

Chucking reamers are installed by machinists and tool-and-die professionals. Power down or lock out the machine before loading or removing the tool from the chuck or collet. Ensure the shank is fully seated and the chuck is tightened to the machine manufacturer specification before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore quality. Never use a reamer to remove more stock than the allowance recommended for finish reaming.
