Hertel 45674991 Chucking Reamer 0.178 in Solid Carbide

Product Description

The HERTEL 45674991 is a solid carbide chucking reamer designed for precision hole finishing in machining operations. With a reamer diameter of 0.178 inches and an overall length of 2.75 inches, this tool delivers tight tolerances in drilled or bored holes. The straight flute design combined with a right-hand cutting direction suits standard CNC and manual lathe applications. A bright polished finish reduces friction and helps maintain cutting edge integrity over extended use. Machinists and toolroom professionals use this reamer when hole geometry and surface finish requirements exceed what a drill alone can achieve.

This chucking reamer is suited for finishing operations in ferrous and non-ferrous materials where dimensional accuracy is critical. The straight shank allows direct chuck mounting in drill presses, lathes, and machining centers. With a 7/8 inch flute length and 4-flute geometry, it is well matched to shallow-to-moderate depth finishing passes in production and job shop environments. It is not configured as a dowel pin reamer or an over/under-size reamer, making it a standard straight-tolerance tool for general precision work.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• 0.178 inch diameter within the 0.1500 to 0.1999 inch decimal range
• 4-flute straight flute geometry for consistent chip flow and surface finish
• Right-hand cutting direction compatible with standard spindle rotation
• Bright polished finish reduces built-up edge and lowers cutting friction
• Straight shank for direct chuck or collet mounting without adapters

Compatibility

Designed as a standard straight-shank chucking reamer for use in drill press chucks, lathe tailstock chucks, and machining center tool holders that accept straight-shank round tooling at 0.178 inch diameter.

Installation Notes

Installation and use should be performed by qualified machinists familiar with reaming procedures and applicable shop safety practices. Secure the straight shank firmly in a chuck or collet before operation and verify runout before committing to a finish pass. Always power down and lock out the machine spindle before changing or adjusting tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality.
