Hertel 45674413 Chucking Reamer 0.0475 in Solid Carbide

Product Description

The HERTEL 45674413 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 0.0475-inch diameter and a 4-flute straight flute geometry, this reamer delivers tight dimensional tolerances and smooth bore finishes in a single pass. The bright (polished) coating reduces friction and promotes chip evacuation. At 1.5 inches overall length with a 0.375-inch flute length and straight shank, it is sized for use in collet chucks, drill chucks, and CNC tool holders. Cutting direction is right hand. Machinists and tool-and-die professionals are the primary users of this type of reamer.

This chucking reamer is suited for finishing small-diameter through-holes and blind holes in ferrous and non-ferrous metals, plastics, and other machinable materials. Its sub-0.05-inch diameter makes it appropriate for precision instrument work, small component manufacturing, and tight-tolerance production environments. The straight shank allows direct clamping in standard collet systems without adapters. It is typically used on CNC machining centers, manual mills, or drill presses where controlled feed and speed are maintained to protect the cutting edge.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• 0.0475-inch diameter for sub-0.05-inch hole finishing applications
• 4-flute straight geometry provides smooth surface finish and accurate sizing
• Bright (polished) finish reduces friction and aids chip flow
• Straight shank compatible with standard collet chucks and drill chucks
• Right-hand cutting direction for conventional machine spindle rotation

Compatibility

Designed as an OEM-style chucking reamer for use in standard straight-shank collet holders, drill chucks, and CNC tooling systems accommodating the 0.0475-inch diameter range.

Installation Notes

This reamer is installed by a machinist or tool-and-die professional. Secure the straight shank firmly in a collet or drill chuck before operation and confirm runout is within acceptable limits for the tolerance required. Always bring the spindle to a full stop before inserting or removing the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
