Hertel 72035306 Chucking Reamer 0.5300 in Hss 6 Flute

Product Description

The HERTEL 72035306 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent bore sizing on a wide range of ferrous and non-ferrous materials. It features a 0.5300-inch cutting diameter, a 2-inch flute length, and an 8-inch overall length. The straight-cylindrical shank allows secure clamping in standard drill chucks or collet holders. With 6 flutes and right-hand cutting direction, it produces smooth, accurate finishes in through-holes and blind holes alike. Licensed machinists and tool-and-die professionals are the primary installers of this tool.

This chucking reamer is suited for use in manual drill presses, CNC machining centers, and turret lathes where tight bore tolerances are required. It fits within the 0.5000- to 0.6999-inch reamer diameter range and is appropriate for production and maintenance machining environments. The straight-flute geometry makes it well-suited for interrupted cuts and shorter chip evacuation paths in softer materials.

Key Features

• 0.5300-inch cutting diameter for precise bore finishing
• 6 straight flutes with right-hand cutting direction
• 8-inch overall length with 2-inch flute length for reach and rigidity
• HSS construction provides toughness across a broad range of workpiece materials
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy
• Straight-cylindrical shank for compatibility with standard chucks and collet systems

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks, collet holders, and floating reamer holders accepting a straight-cylindrical shank in the 0.5300-inch diameter class.

Installation Notes

This reamer is installed and operated by machinists in drill press, lathe, or CNC machining setups. Always secure the shank fully in the chuck or collet before operation and confirm runout with a dial indicator when tight tolerances are required. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never exceed the recommended feed and speed parameters for HSS tooling in your specific machine and material combination.
