Hertel 72006653 Chucking Reamer 0.0665 in Hss 4 Flute

Product Description

The HERTEL 72006653 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metal and light alloy workpieces. With a reamer diameter of 0.0665 inches and an overall length of 3 inches, this tool is built for tight-tolerance bore sizing in drill press, lathe, or CNC machine applications. The straight flute geometry and bright uncoated finish make it well-suited for ferrous and non-ferrous materials where a clean, accurate final diameter is required. Machinists and tool-and-die professionals rely on chucking reamers like this one to bring pre-drilled holes to a precise finished size.

This reamer is intended for use in machine tool setups where the workpiece or tool is held in a chuck or collet. The straight-cylindrical shank allows direct mounting in standard drill chucks, collet holders, or machine spindles. With a flute length of 0.5 inches and right-hand cutting direction, it is suited for through-hole and shallow blind-hole finishing operations in production and job-shop environments. The 0.0665-inch diameter falls within the 0.0500 to 0.0999 inch decimal inch range, making it appropriate for small-diameter precision work.

Key Features

• 0.0665-inch reamer diameter for small-bore precision finishing
• HSS construction provides wear resistance across common workpiece materials
• 4 straight flutes with right-hand cutting direction
• Bright uncoated finish suitable for general-purpose machining
• Straight-cylindrical shank for direct chuck or collet mounting
• 0.5-inch flute length appropriate for shallow and through-hole applications

Compatibility

Designed as an OEM-style replacement and standard production chucking reamer for machine setups accepting straight-cylindrical shank tooling in the 0.0665-inch diameter class.

Installation Notes

Installation is performed by machinists or tool-and-die professionals in a machine tool environment. Ensure the machine spindle is fully stopped and locked before loading or removing the reamer from the chuck or collet. Pre-drill the bore to the appropriate undersize before reaming to avoid overloading the flutes or producing an out-of-tolerance finish. Follow shop standards and applicable machining codes for speeds, feeds, and cutting fluid selection appropriate to the workpiece material.
