Hertel 45677010 Chucking Reamer 0.491 in Solid Carbide

Product Description

The HERTEL 45677010 is a solid carbide chucking reamer designed for precision hole finishing in metalworking applications. With a reamer diameter of 0.491 inches and an overall length of 4 inches, this tool delivers tight dimensional accuracy in drilled or bored holes. The 6-flute, right-hand cutting geometry provides smooth material removal and a consistent surface finish. The bright polished coating reduces friction and aids chip evacuation. Machinists and tool-and-die professionals use this reamer in CNC machining centers, drill presses, and manual lathes where bore tolerance and finish quality are critical.

This chucking reamer is suited for production and job-shop environments requiring accurate hole sizing in ferrous and non-ferrous metals. The straight shank allows direct mounting in standard drill chucks, collets, or floating holders. With a 1.5-inch flute length, it is optimized for through-holes and shallow blind-hole applications at this diameter range. It is a standard individual unit with no special over- or under-size offset.

Key Features

• Solid carbide construction for wear resistance and dimensional stability in hard or abrasive materials
• 0.491-inch reamer diameter within the 0.400 to 0.4999 inch decimal inch range
• 6 straight flutes with right-hand cutting direction for smooth, consistent bore finishing
• Bright polished coating reduces friction and promotes chip flow
• Straight shank compatible with standard drill chucks and collet holders
• 4-inch overall length with 1.5-inch flute length suited for shallow-to-moderate hole depths

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in standard straight-shank toolholders, collets, and drill chucks across CNC and manual machining setups requiring a 0.491-inch finished bore diameter.

Installation Notes

Installation and use should be performed by qualified machinists familiar with reamer tooling practices. Secure the straight shank firmly in a properly sized collet or drill chuck before operation, and confirm the machine spindle is fully stopped before tool changes. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Do not use this reamer to remove excessive stock; pre-drill or bore the hole to within a few thousandths of final diameter before reaming.
