Hertel 45676640 Chucking Reamer 0.395 in Solid Carbide

Product Description

The HERTEL 45676640 is a solid carbide chucking reamer designed for precision hole finishing in machined components. With a 0.395 inch cutting diameter and a 1.25 inch flute length, this reamer removes minimal material to bring drilled or bored holes to tight dimensional tolerances. The bright polished finish reduces friction and aids chip evacuation during the cut. At 3.5 inches overall length, it is suited for use in CNC machining centers, manual mills, and drill presses where accurate hole sizing is required. Licensed machinists and tool-and-die professionals are the primary users of this type of cutting tool.

This chucking reamer is intended for precision reaming applications in metalworking environments, including job shops, production machining, and maintenance repair operations. The straight shank allows direct mounting in standard collet chucks, drill chucks, or floating reamer holders. It is well suited for finishing holes in ferrous and non-ferrous materials where dimensional accuracy and surface finish are critical. The six-flute, right-hand cutting configuration provides smooth, stable cutting action at moderate speeds and feeds.

Key Features

• 0.395 inch cutting diameter within the 0.3500 to 0.3999 inch reamer diameter range
• Solid carbide construction for rigidity and wear resistance in demanding materials
• Six straight flutes with right-hand cutting direction for stable, chatter-free performance
• Bright polished finish reduces friction and promotes clean chip removal
• Straight shank compatible with standard collet chucks and floating holders
• 1.25 inch flute length suited for through-hole and shallow blind-hole applications

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in standard straight-shank toolholders on CNC and manual machine tools requiring a 0.395 inch finished hole diameter.

Installation Notes

Installation and use should be performed by qualified machinists familiar with cutting tool setup and machine tool operation. Ensure the machine spindle is fully stopped and the tool is securely clamped in a properly sized collet or chuck before beginning any operation. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life and maintain surface finish quality. Do not exceed the tool manufacturer's recommended speeds and feeds for solid carbide reamers in the material being machined.
