Hertel 72019003 Chucking Reamer 0.19 in Hss 6 Flute

Product Description

The HERTEL 72019003 is a high-speed steel chucking reamer designed to finish-size drilled or bored holes to a precise 0.1900-inch diameter. Built with 6 straight flutes and a right-hand cutting direction, it delivers clean, accurate bores in a wide range of metals and materials. The straight-cylindrical shank seats securely in standard chucks on drill presses, lathes, and CNC machines. With a 4.5-inch overall length and a 1.125-inch flute length, this reamer handles typical through-hole and shallow blind-hole applications in production and job-shop environments. The bright, uncoated HSS construction is suited for general-purpose reaming at moderate speeds.

This chucking reamer is used in machine-shop, maintenance, and manufacturing environments where hole finishing to close tolerances is required. It is appropriate for ferrous and non-ferrous workpieces in both manual and CNC setups. Machinists and toolmakers reach for straight-flute chucking reamers when hole geometry demands consistent surface finish and dimensional accuracy across repeated operations. The 0.1900-inch diameter falls within the 0.1500 to 0.1999 inch reamer diameter range, making it a standard intermediate size for precision hole finishing.

Key Features

• 0.1900-inch finished-bore diameter for precise hole sizing
• 6 straight flutes for clean cutting action and efficient chip clearance
• Right-hand cutting direction compatible with standard machine spindle rotation
• High-speed steel construction provides toughness across general-purpose materials
• Bright uncoated finish — suitable for use with cutting fluids on most common workpiece materials
• Straight-cylindrical shank for secure chuck retention on drill presses, lathes, and machining centers

Compatibility

Designed as a standard chucking reamer for use in drill press, lathe, or CNC machine chucks accepting a straight-cylindrical shank; compatible with applications requiring a 0.1900-inch finished hole diameter.

Installation Notes

Installation and use should be performed by qualified machinists or toolmakers familiar with reaming operations and machine tool safety. Always power down and bring the spindle to a complete stop before inserting or removing the reamer from the chuck. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Ensure the pre-drilled or bored hole is sized correctly undersize before reaming to avoid tool deflection or excessive cutting load.
