Hertel 72036908 Chucking Reamer 0.690 in Hss 8 Flute

Product Description

The HERTEL 72036908 is a straight-flute chucking reamer designed to finish-ream precision bores to a nominal diameter of 0.6900 inches. Built from high-speed steel (HSS) with a bright uncoated finish, it delivers clean, accurate hole sizing in a wide range of ferrous and non-ferrous materials. The 8-flute configuration distributes cutting load evenly, reducing chatter and improving surface finish in the reamed bore. With an overall length of 9 inches and a flute length of 2.25 inches, this reamer is suited for through-hole and shallow blind-hole applications where tight dimensional tolerances are required. It weighs 0.23 pounds and mounts via a straight-cylindrical shank for use in drill presses, lathes, and CNC machining centers.

This chucking reamer is used in machine shop, maintenance, and production environments where bore finishing is required after drilling or boring. The right-hand cutting direction is standard for conventional spindle rotation. It is appropriate for jobbing and toolroom work where holes must be brought to a precise final diameter with consistent surface finish across multiple parts.

Key Features

• 0.6900 inch nominal reaming diameter for precise bore sizing
• 8 straight flutes for even load distribution and improved surface finish
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Bright uncoated finish — ready to use or compatible with field-applied cutting fluids
• Straight-cylindrical shank fits standard drill chucks, collets, and machine spindles
• Right-hand cutting direction for use with standard spindle rotation

Compatibility

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

Installation Notes

This reamer is installed and operated by machinists in machine shop or maintenance settings. Power down and lock out the machine spindle before installing or removing the reamer from the chuck or collet. Use appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Do not use a chucking reamer to remove excessive stock — pre-drill or bore the hole to within accepted reaming allowance before finishing with this tool.
