Hertel 45676137 Chucking Reamer 0.328 in Solid Carbide

Product Description

The HERTEL 45676137 is a solid carbide chucking reamer designed to bring holes to a precise finished diameter with tight tolerances. The 0.328-inch cutting diameter and 6-flute straight geometry produce a smooth, accurate bore suitable for close-tolerance work in metalworking, toolroom, and production machining environments. At 3.5 inches overall length with a 1.25-inch flute length, this reamer fits standard drill press, lathe, and CNC machine tool chucks via its straight cylindrical shank. Solid carbide construction provides superior rigidity and wear resistance compared to high-speed steel, making it well-suited for harder workpiece materials and higher-cycle production runs. The bright, uncoated finish keeps the tool ready to use out of the box.

This chucking reamer is appropriate for use in machine shop, toolroom, and light production applications where hole quality and dimensional accuracy are the priority. The straight flute design works reliably in through-holes and short blind-hole conditions across a range of ferrous and non-ferrous materials. It is sized within the 0.300 to 0.349 inch diameter range, making it a common choice for precision bore finishing in both job-shop and production-floor settings. Licensed machinists and tool-and-die technicians are the typical end users.

Key Features

• 0.328-inch cutting diameter for precise bore finishing
• Solid carbide construction for rigidity, wear resistance, and longer tool life
• 6-flute straight configuration for smooth surface finish in through-holes
• Straight cylindrical shank for compatibility with standard drill chucks and collets
• Right-hand cutting direction
• Bright uncoated finish — no post-treatment required before use

Compatibility

Designed as a machine-style chucking reamer for use in drill presses, lathes, machining centers, and similar equipment with standard chuck or collet toolholding capable of accepting a straight cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by qualified machinists. Always power down and lock out the machine spindle before securing or removing the tool from the chuck or collet. Ensure the shank is fully seated and the holder is properly tightened before running the spindle. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.
