Hertel 45675774 Chucking Reamer 0.28 in Solid Carbide

Product Description

The HERTEL 45675774 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 0.28-inch diameter, a 3.25-inch overall length, and a 1.125-inch straight flute length, this reamer delivers consistent bore sizing and surface finish in production environments. The bright, uncoated solid carbide construction provides rigidity and edge retention suited to close-tolerance work. Six straight flutes and a right-hand cutting direction ensure smooth chip evacuation and stable cutting action. Machinists and tool-and-die professionals install this type of reamer as the final sizing pass after drilling or boring.

This chucking reamer is appropriate for use on CNC machining centers, knee mills, and drill presses wherever a straight-shank cylindrical tool is required. It is well suited to finishing bores in steel, cast iron, aluminum, and similar workpiece materials in both job shop and production floor settings. The straight-cylindrical shank seats directly in a drill chuck, collet, or floating reamer holder without modification.

Key Features

• Solid carbide construction for high rigidity and extended edge life compared to HSS tooling
• 0.28-inch reamer diameter for precise hole finishing in the 0.25 to 0.30-inch range
• Six straight flutes for smooth cutting action and efficient chip clearance
• Right-hand cutting direction, compatible with standard spindle rotation
• Bright, uncoated finish suitable for use with most cutting fluids
• Straight-cylindrical shank fits standard chucks and collets without adapters

Compatibility

Designed as an OEM-style chucking reamer for use in any machine tool equipped to accept a straight-cylindrical shank tool at 0.28-inch finished bore diameter.

Installation Notes

Chucking reamers are installed and serviced by machinists following standard machine shop practices. Power down and lock out the spindle before inserting or removing the tool from the chuck or collet. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality. Ensure the bore is pre-drilled or bored to the correct undersize before reaming, as reamers are finishing tools and are not designed to remove heavy stock.
