Hertel 2290401 Chucking Reamer 5/8 in Hss Straight Flute

Product Description

The HERTEL 2290401 is a straight-flute chucking reamer designed for precision hole finishing in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent bore sizing in drilling and machining operations. The reamer measures 0.625 inches in diameter and runs 9 inches in overall length, with a 2.25-inch flute length that provides controlled chip clearance during through-hole and blind-hole finishing passes. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. Right-hand cutting direction follows conventional spindle rotation. Machinists and tool-and-die professionals use this reamer to bring drilled holes to final dimensional tolerance.

This chucking reamer is suited for general-purpose metalworking applications including manual mills, CNC machining centers, drill presses, and lathes. It is sized in the 0.5000 to 0.6999 decimal inch diameter range and targets production and maintenance environments where precise hole sizing to 5/8 inch is required. The bright finish makes it appropriate for a wide range of ferrous and non-ferrous materials where coating buildup is not a concern.

Key Features

• 0.625 inch (5/8 inch) reamer diameter for finish-sizing drilled holes to close tolerance
• High-speed steel (HSS) construction provides wear resistance across common machining materials
• Straight flute geometry promotes smooth cutting action and easy chip evacuation
• Bright, uncoated finish suitable for general ferrous and non-ferrous applications
• Straight-cylindrical shank compatible with standard drill chucks and collet systems
• Right-hand cutting direction for use with standard forward spindle rotation

Compatibility

Designed as a standard chucking reamer for use in drill presses, mills, lathes, and CNC machining centers that accept straight-cylindrical shank tooling in the 5/8 inch diameter class.

Installation Notes

Install and remove tooling only with the machine spindle fully stopped and the power source locked out per applicable shop safety procedures. Secure the straight-cylindrical shank firmly in a properly sized drill chuck or collet to minimize runout before use. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Follow ANSI and shop-specific machining standards for feed rate and spindle speed selection when reaming.
