Hertel 45675956 Chucking Reamer 0.304 in Solid Carbide

Product Description

The HERTEL 45675956 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a reamer diameter of 0.304 inches and an overall length of 3.25 inches, this tool delivers tight dimensional tolerances in drilled or bored holes. The six-flute, right-hand cutting geometry combined with a bright polished finish reduces friction and promotes smooth chip evacuation. Machinists and tool and die professionals install this reamer in a lathe chuck or drill press to bring pre-drilled holes to final size with consistent accuracy.

This chucking reamer is suited for finishing operations in ferrous and non-ferrous materials where hole diameter precision is critical. The straight shank design allows direct mounting in a standard drill chuck or collet. With a 1.125-inch flute length, it is appropriate for shallow-to-moderate depth reaming passes in production or job-shop environments. It is sold as a single unit and is well matched to CNC machining centers, manual mills, and lathes requiring a reliable straight-shank tool.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• 0.304-inch reamer diameter for precise hole finishing within the 0.300 to 0.3499-inch range
• Six-flute right-hand cutting geometry for smooth stock removal and surface finish
• Bright polished coating reduces built-up edge and improves chip flow
• Straight shank compatible with standard drill chucks and collet holders
• 1.125-inch flute length suitable for shallow and moderate reaming depths

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks, collets, and collet chuck systems accepting straight-shank tooling in the 0.300 to 0.3499-inch diameter range.

Installation Notes

Installation is performed by qualified machinists or tool and die technicians. Ensure the machine spindle is fully stopped and the chuck is secured before inserting or removing the reamer. The pre-drilled hole should be sized appropriately to leave only the recommended stock allowance for reaming. Do not force or side-load a chucking reamer, as this can cause premature edge failure in carbide tooling.
