Hertel 79888871 Chucking Reamer 0.0505 in Solid Carbide

Product Description

The HERTEL 79888871 is a solid carbide chucking reamer designed for precision hole finishing in metalworking applications. With a reamer diameter of 0.0505 inches and a tight diameter tolerance of 0.0000 to 0.0002 inches, this tool delivers accurate, repeatable bore sizing in production and toolroom environments. The straight flute geometry and right-hand cut make it well suited for reaming through holes in a variety of ferrous and non-ferrous materials. Machinists and tool and die professionals install this reamer in CNC machining centers, drill presses, and manual lathes wherever close-tolerance hole finishing is required.

This reamer is appropriate for small-diameter precision work in manufacturing, aerospace component production, mold and die shops, and general machine shops. Its 1.5-inch overall length and 0.375-inch flute length make it a compact tool for shallow hole applications. The bright uncoated finish suits general-purpose use across a range of workpiece materials. It is sold individually and is well matched to applications calling for diameters in the 0.0500 to 0.0999 inch range.

Key Features

• Solid carbide construction provides rigidity and wear resistance for tight-tolerance reaming
• 0.0505-inch reamer diameter with tolerance of 0.0000 to 0.0002 inches for precise bore sizing
• Straight flute, right-hand cut geometry suited for through-hole reaming
• Straight cylindrical shank for direct chuck mounting on standard equipment
• 4-flute design balances cutting efficiency with surface finish quality
• Bright uncoated finish for general-purpose use across common workpiece materials

Compatibility

Designed as a standard chucking reamer with a straight cylindrical shank, compatible with drill chucks and collets sized for the shank diameter on CNC machining centers, drill presses, and manual lathes.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practices. Secure the straight shank firmly in a drill chuck or collet before operation and verify runout before cutting. Power down and de-energize the machine spindle before changing or adjusting tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
