Hertel 72035645 Chucking Reamer 0.564 in Hss Straight

Product Description

The HERTEL 72035645 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing in a wide range of ferrous and non-ferrous materials. The reamer measures 0.5640 inches in diameter with an overall length of 8 inches and a 2-inch flute length. The straight-cylindrical shank seats securely in standard drill chucks or collet holders, and the 8-flute geometry provides smooth, consistent surface finish on finish-reamed bores. Right-hand cutting direction is standard for conventional CNC and manual spindle operation.

This chucking reamer is suited for job shop, production, and maintenance machining environments where close-tolerance holes are required. It fits within the 0.5000 to 0.6999 inch reamer diameter range and is appropriate for use on lathes, milling machines, and drill presses where a chucking-style reamer is the specified tool. Machinists, toolroom operators, and production line technicians are the primary users. It is sold in single-unit quantities with no minimum order beyond one piece.

Key Features

• 0.5640 inch finished bore diameter for precise hole sizing
• 8-flute straight configuration for smooth surface finish and even chip load
• High-speed steel (HSS) construction handles a broad range of workpiece materials
• Bright, uncoated finish — suitable for use with cutting fluids as required by the workpiece material
• Straight-cylindrical shank for secure seating in standard chucks and collet holders
• Right-hand cutting direction compatible with conventional spindle rotation

Compatibility

Designed as a standard chucking reamer for use in any machine tool spindle that accepts a straight-cylindrical shank in the corresponding diameter range, including lathes, knee mills, and drill presses.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with reaming operations. Ensure the spindle and workpiece are fully secured before engaging the reamer, and power down the machine before changing or inspecting tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Follow shop safety protocols and applicable OSHA machine guarding requirements when operating rotating tooling.
