Hertel 2291466 Chucking Reamer Wire 46 Hss 4 Flute

Product Description

The HERTEL 2291466 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it machines wire size 46 holes to a finished diameter of 0.0810 inches. The straight-cylindrical shank seats securely in a drill chuck or collet, and the 4-flute right-hand cutting geometry delivers clean, accurate bores. With a 3-inch overall length and a 3/4-inch flute length, this reamer is suited for shallow through-holes and blind holes in close-tolerance work. Machinists, tool and die makers, and maintenance technicians install this tool in CNC machining centers, drill presses, and manual mills.

This reamer is used in production and maintenance machining environments where wire-gauge holes require tight dimensional control. The 0.0810-inch diameter fits applications in light-gauge metal fabrication, instrument manufacturing, and general precision drilling work. Wire size reamers in this range are common in aerospace maintenance, electronics enclosure work, and fixture building where standard fractional sizes do not match the required bore specification.

Key Features

• Wire size 46 cutting diameter of 0.0810 inches for precision bore finishing
• High-speed steel (HSS) construction provides durability in ferrous and non-ferrous materials
• 4-flute straight geometry for clean chip evacuation in shallow holes
• Right-hand cutting direction compatible with standard machine spindle rotation
• Bright, uncoated finish suitable for general-purpose reaming without coolant-reactive coatings
• Straight-cylindrical shank for direct chuck or collet mounting

Compatibility

Designed as a standard wire-size chucking reamer for use in drill presses, CNC machining centers, and manual milling machines equipped with a drill chuck or collet capable of holding a straight-cylindrical shank at this diameter range.

Installation Notes

Installation and use of this tool should be performed by a qualified machinist familiar with reaming procedures and machine tool operation. Power down and lock out the spindle before mounting or removing the reamer from the chuck or collet. Ensure the shank is fully seated and the chuck is tightened to prevent runout, which can cause oversize or bell-mouthed bores. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
