Hertel 45676517 Chucking Reamer 0.372 in Solid Carbide

Product Description

The HERTEL 45676517 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production environments. With a reamer diameter of 0.372 inches and a straight shank, this tool mounts directly in a drill chuck or collet holder for accurate, repeatable results. The 6-flute right-hand cutting geometry distributes cutting load evenly, reducing chatter and improving surface finish in the final bore. A bright polished finish minimizes friction and aids chip evacuation. The 1.25-inch flute length and 3.5-inch overall length make it well suited for moderate-depth holes in ferrous and non-ferrous materials.

This chucking reamer is used in CNC machining centers, manual mills, and drill presses where final bore tolerances and surface finish are critical. It is appropriate for production runs and job shop work on steel, cast iron, aluminum, and similar materials where a precise, finished hole is required after drilling or boring. The straight flute design performs best in through-holes and stable cutting conditions. Machinists and toolroom professionals are the primary users of this tool.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• 6-flute right-hand cutting design for smooth, accurate bore finishing
• Bright polished finish reduces friction and assists chip flow
• Straight flute geometry suited for through-holes and stable setups
• Straight shank for straightforward chuck or collet mounting
• 0.372 inch diameter falls within the 0.3500 to 0.3999 inch reamer diameter range

Compatibility

Designed as a standard chucking reamer for use in any machine tool equipped with a drill chuck or straight-shank collet holder accepting a 0.372-inch diameter straight-shank tool.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Secure the straight shank firmly in a properly sized collet or drill chuck before operation, and verify runout with a dial indicator when tolerance is critical. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish. Never use this reamer to remove excessive stock — pre-drill or bore the hole to within a few thousandths of final diameter before reaming.
