Hertel 45675568 Chucking Reamer 0.247 in Solid Carbide

Product Description

The HERTEL 45675568 is a solid carbide chucking reamer designed for precision hole finishing in machining operations. With a reamer diameter of 0.247 inches and a 4-flute straight flute geometry, it delivers consistent sizing and smooth surface finishes in through and blind holes. The straight cylindrical shank provides secure chuck retention on standard drill presses, CNC machining centers, and manual lathes. Overall length is 3 inches with a 1-inch flute length. The bright uncoated finish suits general-purpose ferrous and non-ferrous applications where coating buildup is a concern. Machinists and tool room operators select this reamer when tight dimensional tolerances are required after drilling.

This chucking reamer is suited for production and job shop environments where hole diameters in the 0.2000 to 0.2499 inch range require finishing passes. Right-hand cutting direction makes it compatible with standard CNC and manual spindle rotation. The solid carbide construction handles harder workpiece materials and maintains edge integrity at higher cutting speeds compared to high-speed steel alternatives. It is sold individually and is a common selection for aerospace, automotive, and general precision machining applications.

Key Features

• Solid carbide construction for extended edge life in demanding materials
• 0.247 inch reamer diameter within the 0.2000 to 0.2499 inch range
• 4-flute straight flute geometry for consistent hole sizing and finish
• Straight cylindrical shank for direct chuck or collet mounting
• Bright uncoated finish suitable for general-purpose ferrous and non-ferrous use
• Right-hand cut compatible with standard machine spindle rotation

Compatibility

Designed as a general-purpose chucking reamer for use in standard drill chucks, collet chucks, and floating reamer holders on CNC machining centers, drill presses, and manual lathes running right-hand spindle rotation.

Installation Notes

This reamer is installed and serviced by machinists and tool room personnel. Secure the straight shank firmly in a drill chuck or precision collet before operation and verify runout within acceptable limits to maintain hole tolerance. Power down and lock out the machine spindle before changing tooling. Do not use this reamer as a drill; always pre-drill or bore the hole close to final size before reaming.
