Hertel 59904565 Chucking Reamer 9/32 in Solid Carbide 6 Flute

Product Description

The HERTEL 59904565 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 9/32 inch (0.2812 inch) cutting diameter, 3-1/4 inch overall length, and 1-1/8 inch flute length, this reamer delivers consistent bore sizing and fine surface finishes in through and blind holes. The tool features 6 spiral flutes with a right-hand cutting direction, promoting efficient chip evacuation and smooth cutting action. The straight-cylindrical shank provides secure tool holding in standard drill chucks or collet holders. Machinists and tool-room professionals install this type of reamer as a finishing step after drilling to achieve close-tolerance hole diameters.

This chucking reamer is suited for use on CNC machining centers, manual lathes, drill presses, and knee mills where repeatable hole sizing is required. It is appropriate for finishing holes in ferrous and non-ferrous materials where solid carbide tooling is specified for hardness, wear resistance, or surface finish requirements. The right-hand spiral flute geometry makes it well matched to general-purpose reaming operations in production and job-shop environments.

Key Features

• Solid carbide construction for superior hardness and wear resistance compared to high-speed steel alternatives
• 6 spiral flutes with right-hand cutting direction for efficient chip removal and smooth bore finish
• 0.2812 inch (9/32 inch) cutting diameter for precision hole sizing in the 0.2500 to 0.2999 inch range
• 3-1/4 inch overall length with 1-1/8 inch flute length for reach in standard workpiece depths
• Straight-cylindrical shank for direct mounting in drill chucks, collet chucks, or floating reamer holders
• Right-hand spiral flute geometry promotes upward chip flow and reduced chatter in typical reaming conditions

Compatibility

Designed as a standard chucking reamer for use in any machine tool spindle accepting a straight-cylindrical shank, including CNC machining centers, drill presses, lathes, and milling machines equipped with appropriate toolholding.

Installation Notes

Chucking reamers are installed by machinists in a drill chuck, collet, or floating holder before the machine is powered on and the spindle is confirmed stationary. The workpiece and fixture must be securely clamped prior to reaming. Always run the reamer at the correct speed and feed for the material being cut — solid carbide reamers are sensitive to side loading and should not be used to remove excess stock; pre-drill or bore to within 0.005 to 0.015 inch of final diameter before reaming. Use appropriate cutting fluid for the workpiece material to maximize tool life and surface finish.
