Hertel 85705192 Chucking Reamer 0.7495 in Hss 8 Flute

Product Description

The HERTEL 85705192 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metal fabrication and machining applications. With a 0.7495-inch diameter and an 8-flute straight-flute configuration, this reamer delivers consistent sizing and smooth surface finish in drilled or bored holes. The bright, uncoated finish is standard for general-purpose HSS tooling. At 9.5 inches overall length with a 2.5-inch flute length, this tool is suited for through-hole and blind-hole reaming where reach and rigidity matter. Machinists and tool-and-die professionals are the primary users of this type of tooling.

This chucking reamer is intended for use in manual and CNC machine tools — including lathes, drill presses, and machining centers — where it is held in a chuck or collet via its straight-cylindrical shank. The right-hand cutting direction is the standard orientation for conventional reaming operations. The 0.7495-inch diameter positions this tool within the 0.7000 to 0.9999-inch decimal inch reamer range, making it appropriate for finishing holes to close-tolerance specifications in production and job-shop environments.

Key Features

• 0.7495-inch diameter for precise hole sizing within the 0.7000 to 0.9999-inch range
• 8 straight flutes for smooth cutting action and consistent finish
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Bright uncoated finish — suitable for general-purpose machining applications
• Straight-cylindrical shank for secure chuck or collet holding
• Right-hand cutting direction, standard for conventional reaming operations

Compatibility

Designed as a standard chucking reamer for use in machine tools equipped with a chuck or collet capable of accepting a straight-cylindrical shank in the 0.7495-inch decimal inch diameter class.

Installation Notes

Installation and use of this reamer should be performed by qualified machinists familiar with proper speeds and feeds for HSS tooling. Ensure the machine spindle is fully stopped and locked out before securing or removing the reamer from the chuck or collet. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Never exceed the reamer's rated cutting capacity or apply side-loading forces that could cause deflection or tool breakage.
