Hertel 72293756 Chucking Reamer 0.4980 in Hss 6 Flute

Product Description

The HERTEL 72293756 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metalworking applications. With a reamer diameter of 0.4980 inches, a 6-inch overall length (OAL), and a 2-inch straight flute length, this tool delivers consistent bore sizing and smooth surface finish in production and job-shop environments. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. Six straight flutes provide even chip evacuation and stable cutting action. Machinists, tool-and-die makers, and CNC operators use this reamer to bring drilled or bored holes to close tolerance. HSS construction handles a wide range of workpiece materials at moderate cutting speeds.

This chucking reamer is suited for through-hole and blind-hole reaming operations on lathes, drill presses, milling machines, and CNC machining centers. It is appropriate for general-purpose production work where a 0.4980-inch finished bore diameter is required. The straight flute geometry makes it a practical choice for most ferrous and non-ferrous materials in standard shop conditions. This tool ships as a single unit and is stocked individually for replacement or tooling builds.

Key Features

• 0.4980-inch reamer diameter falls within the 0.4000 to 0.4999 decimal inch range for close-tolerance finishing
• HSS tool material provides durability and resharpening capability across a broad material range
• 6-inch OAL with 2-inch flute length accommodates standard reach requirements on most machine setups
• Six straight flutes promote even cutting load distribution and smooth chip removal
• Straight-cylindrical shank compatible with standard drill chucks and ER collet systems
• Dowel pin reamer geometry suitable for precision locating hole applications

Compatibility

Designed as a standard chucking reamer for use in drill chucks, collet holders, and floating reamer holders on lathes, drill presses, milling machines, and CNC machining centers requiring a 0.4980-inch finished bore diameter.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with reaming feeds, speeds, and cutting fluid requirements for the workpiece material. Ensure the shank is fully seated and securely clamped in the chuck or collet before operation. Pre-drill or bore the hole to the appropriate undersize before reaming to avoid overloading the flutes. Do not reverse the reamer under load, as this can damage the cutting edges.
