Hertel 72019300 Chucking Reamer 0.1930 in Hss 6 Flute

Product Description

The HERTEL 72019300 is a straight-flute chucking reamer designed for precision hole finishing in metal and other materials requiring tight dimensional tolerances. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer holds a 0.1930-inch cutting diameter and delivers a right-hand cutting action across 6 straight flutes. The 5-inch overall length and 1.25-inch flute length make it well suited for general-purpose reaming in standard-depth through and blind holes. Machinists and toolroom technicians install this tool in CNC machines, drill presses, and manual lathes using standard chucks or collet systems.

This chucking reamer is intended for finish reaming operations where a precise, smooth bore is required after drilling. The straight-cylindrical shank allows straightforward mounting in a wide range of machine tool spindles and chucks without additional adapters in most setups. Typical applications include reaming clearance holes, bearing bores, and pin-fit holes in production and job-shop environments. The 0.1930-inch diameter falls within the 0.1500 to 0.1999 inch reamer diameter range, making it a standard selection for close-tolerance finish work in that size class.

Key Features

• 0.1930-inch cutting diameter for close-tolerance finish reaming
• HSS construction provides durability across a range of workpiece materials
• 6 straight flutes deliver consistent chip evacuation and smooth bore finish
• Right-hand cutting direction compatible with standard machine spindle rotation
• Bright, uncoated finish suitable for general-purpose applications
• Straight-cylindrical shank for direct chuck or collet mounting

Compatibility

Designed as a standard chucking reamer for use in CNC machining centers, drill presses, turret lathes, and similar machine tools accepting a straight-cylindrical shank in the corresponding diameter range.

Installation Notes

Installation should be performed by a qualified machinist following safe toolroom practices. Secure the straight-cylindrical shank firmly in a compatible chuck or collet before operation and verify runout is within acceptable limits for the required tolerance. Always bring the spindle to a complete stop before removing or changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore quality.
