Hertel 72019151 Chucking Reamer 0.1915 in Hss 6 Flute

Product Description

The HERTEL 72019151 is a straight-flute chucking reamer designed for precision hole finishing in metal workpieces. With a cutting diameter of 0.1915 inches and a 6-flute right-hand cutting geometry, it delivers smooth, accurate bores in production and job-shop environments. The reamer is manufactured from high-speed steel (HSS) with a bright, uncoated finish suited to general-purpose ferrous and non-ferrous applications. Overall length is 5 inches with a 1.25-inch flute length and a straight-cylindrical shank for secure chuck holding. Machinists, toolroom technicians, and CNC operators install this tool in drill presses, lathes, and machining centers where tight hole tolerances are required.

This chucking reamer is intended for finishing pre-drilled or bored holes to close dimensional tolerances in machine shop and manufacturing settings. It is suited to both manual and CNC machine tool applications where a straight-cylindrical shank accommodates standard drill chucks or collet systems. The 0.1915-inch diameter falls within the 0.1500 to 0.1999-inch reamer diameter range, making it appropriate for fine pilot holes, pin fits, and precision clearance work across light-to-medium production volumes.

Key Features

• 0.1915-inch cutting diameter for precision hole finishing to tight tolerances
• 6-flute straight configuration provides smooth surface finish and even chip distribution
• Right-hand cutting direction for standard clockwise spindle operation
• HSS construction offers good toughness and wear resistance for general-purpose machining
• Bright uncoated finish suitable for use with cutting fluids on a wide range of materials
• Straight-cylindrical shank compatible with standard drill chucks and collet holders

Compatibility

Designed as a standard chucking reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers equipped with a drill chuck or collet system that accepts a straight-cylindrical shank.

Installation Notes

This tool is installed by a machinist or toolroom technician. Power down and lock out the machine spindle before securing or removing the reamer from the chuck or collet. Always ream a pre-drilled or bored hole that is undersized by the appropriate allowance for the diameter and material — do not ream from solid. Apply a suitable cutting fluid for the workpiece material to extend tool life and improve surface finish.
