Hertel 45676491 Chucking Reamer 0.37 in Solid Carbide

Product Description

The HERTEL 45676491 is a solid carbide chucking reamer designed for precision hole finishing in machine-tool applications. With a 0.37-inch diameter and a bright, uncoated finish, it delivers tight dimensional tolerances in ferrous and non-ferrous materials. The 6-flute straight configuration provides smooth, even cutting action along its 1.25-inch flute length. At 3.5 inches overall length, this reamer fits standard drill-press and CNC lathe chuck setups. Machinists and tool-and-die technicians use it where bore accuracy and surface finish are critical. Solid carbide construction offers rigidity and wear resistance superior to high-speed steel in harder workpiece materials.

This chucking reamer is suited for production machining environments where precise hole sizing is required after drilling. Its straight cylindrical shank mounts directly in a drill chuck, collet, or machine spindle without adapters. Right-hand cutting direction makes it compatible with conventional forward-rotation machine setups. It is not configured as a dowel pin reamer or an over/under size reamer, making it a standard finish-reaming tool for holes in the 0.35 to 0.39-inch diameter range.

Key Features

• 0.37-inch diameter for precision finish reaming in the 0.35-0.3999-inch range
• Solid carbide construction for rigidity and extended tool life
• 6 straight flutes for consistent cutting action and smooth bore finish
• 1.25-inch flute length provides adequate engagement for through and blind holes
• Bright, uncoated finish — suitable for use with cutting fluids across a range of workpiece materials
• Straight cylindrical shank for direct chuck or collet mounting

Compatibility

Designed as a standard chucking reamer for use in drill presses, CNC lathes, and machining centers that accept a straight cylindrical shank tool in conventional right-hand rotation.

Installation Notes

Installation is performed by qualified machinists familiar with rotating cutting tools and machine-tool operation. Power down and lock out the machine spindle before mounting or removing the reamer. Secure the straight shank firmly in a drill chuck or collet to minimize runout, which directly affects hole tolerance and tool life. Always apply an appropriate cutting fluid for the workpiece material and never reverse spindle direction while the reamer is engaged in the bore.
