Hertel 79556395 Chucking Reamer 1-9/16 in Hss 12 Flute

Product Description

The HERTEL 79556395 is a chucking reamer designed for precision hole finishing in metal machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer measures 1-9/16 inches (1.5625 inches) in diameter and features a 13-inch overall length with a 3-1/2-inch straight flute length. The straight-cylindrical shank allows for secure chuck mounting on drill presses, lathes, and milling machines. With 12 right-hand flutes, the tool produces smooth, accurate bores that meet close-tolerance requirements. It is intended for use by machinists and tool-and-die professionals working with standard machine setups.

This chucking reamer is suited for production and maintenance machining environments where precise bore finishing is required. The 1-9/16-inch diameter targets larger bore work common in industrial components, fixtures, and mechanical assemblies. The straight flute geometry performs well in through-hole applications and works effectively with a range of ferrous and non-ferrous materials when appropriate cutting fluids are applied. The right-hand cutting direction is compatible with standard spindle rotation on conventional machine tools.

Key Features

• 1-9/16 inch (1.5625 inch) reamer diameter for large-bore finishing work
• 12 straight flutes for smooth surface finish and accurate sizing
• High-speed steel (HSS) construction provides durability across a range of materials
• Bright, uncoated finish suitable for use with cutting fluids
• Straight-cylindrical shank for secure, concentric chuck holding
• Right-hand cutting direction matches standard machine spindle rotation

Compatibility

Designed as an OEM-style chucking reamer compatible with standard drill press, lathe, or milling machine chucks that accept a straight-cylindrical shank in the appropriate diameter range.

Installation Notes

Installation and operation should be performed by a qualified machinist. Secure the straight-cylindrical shank firmly in a machine chuck before operation and verify runout with an indicator before cutting. Power down and lock out the machine spindle before changing or adjusting the tool. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and maintain bore quality.
