Hertel 72016504 Chucking Reamer 0.165 in Hss 6 Flute

Product Description

The HERTEL 72016504 is a straight-flute chucking reamer designed for precision hole finishing in metal and other machinable materials. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing for close-tolerance bores. The reamer measures 0.1650 inches in diameter with a 4.5-inch overall length and a 1.125-inch flute length. Six right-hand cutting flutes provide smooth stock removal and consistent surface finish. The straight-cylindrical shank seats securely in standard chucks and collets. This tool is suited for machine-shop and production environments where hole accuracy and repeatability are required.

This chucking reamer is used in drilling and boring operations where a drilled hole must be brought to a precise final diameter. It is appropriate for CNC machining centers, drill presses, lathes, and manual milling setups. The 0.1650-inch diameter falls within the 0.1500 to 0.1999-inch range, making it a standard choice for finishing holes in that size class across a variety of workpiece materials. It is installed by machinists and tool-and-die professionals in both production and job-shop settings.

Key Features

• 0.1650-inch reamer diameter for precise hole finishing
• High-speed steel (HSS) construction for durability across common work materials
• Bright/uncoated finish — no added coating thickness to affect dimensional accuracy
• 6 straight flutes with right-hand cutting direction for smooth, consistent material removal
• Straight-cylindrical shank for secure chuck or collet mounting
• 4.5-inch overall length with 1.125-inch flute length for standard reach applications

Compatibility

Designed as a standard chucking reamer for use in any machine tool equipped with a chuck or collet capable of accepting a straight-cylindrical shank in the 0.1650-inch diameter class.

Installation Notes

This reamer is installed by machinists and should be secured firmly in a chuck or collet before use. Always power down and lock out the machine spindle before changing tooling. Reamers require a pre-drilled hole sized appropriately undersized relative to the finished diameter — do not use as a primary drilling tool. Follow applicable shop safety practices and machine manufacturer guidelines for speed and feed selection when reaming HSS tooling.
