Hertel 59904557 Chucking Reamer 7/32 in Solid Carbide

Product Description

The HERTEL 59904557 is a solid carbide chucking reamer designed for precision hole finishing in metalworking applications. Built with a straight-cylindrical shank and four right-hand spiral flutes, it delivers accurate, repeatable bore sizing in a single pass. The reamer measures 0.2188 inches (7/32 inch) in diameter with an overall length of 3 inches and a flute length of 1 inch. Solid carbide construction provides the rigidity and wear resistance needed to hold tight tolerances in ferrous and non-ferrous materials. This tool is intended for use by machinists and toolroom professionals in CNC and manual drilling setups.

This chucking reamer is suited for precision reaming operations where bore geometry and surface finish are critical. Typical applications include finishing drilled or bored holes to close tolerances in production machining, tool and die work, and general metalworking. The straight-cylindrical shank seats directly into standard collets, chucks, and reamer holders on mills, lathes, and drill presses. Right-hand cutting direction is standard for conventional feed setups.

Key Features

• Solid carbide construction for superior hardness, wear resistance, and dimensional stability
• Four right-hand spiral flutes for smooth chip evacuation and consistent surface finish
• 7/32 inch (0.2188 inch) reamer diameter for accurate hole sizing
• Straight-cylindrical shank compatible with standard collets and chucks
• 3 inch overall length with 1 inch flute length for compact rigidity in short-reach applications
• Right-hand cutting direction for standard CNC and manual machine setups

Compatibility

Designed as an OEM-style chucking reamer for use in standard collet chucks, drill chucks, and reamer holders that accept straight-cylindrical shanks on CNC machining centers, lathes, and drill presses.

Installation Notes

Installation is performed by qualified machinists. Secure the straight-cylindrical shank firmly in a collet or chuck before operation and verify runout before cutting. Ensure spindle speed and feed rate are appropriate for the workpiece material and reamer diameter before engaging the cut. Never use a worn or damaged holder, as runout will compromise bore tolerance and shorten tool life.
