Hertel 2410074 Chucking Reamer 7/64 in Hss 4 Flute

Product Description

The HERTEL 2410074 is a high-speed steel (HSS) chucking reamer designed to bring bored or drilled holes to precise final diameter. Built with a straight-cylindrical shank for secure chuck mounting, this reamer features 4 spiral flutes with a left-hand spiral and right-hand cutting direction. The 7/64-inch (0.1094 inch decimal) diameter and bright, uncoated HSS construction make it well suited for finishing operations in a wide range of ferrous and non-ferrous materials. At 3-1/2 inches overall length with a 7/8-inch flute length, it handles light-to-moderate stock removal to achieve tight bore tolerances in production and job shop environments.

This chucking reamer is used in machine tool setups where holes must meet close dimensional tolerances after drilling or boring. It is appropriate for use in drill presses, lathes, and milling machines in manufacturing, maintenance, and repair operations. The straight-cylindrical shank fits standard drill chucks and collets. It is suitable for general machining work across metalworking trades and industrial maintenance settings where consistent hole quality is required.

Key Features

• 7/64 inch (0.1094 inch decimal) reamer diameter for precise final hole sizing
• HSS tool material provides hardness and wear resistance across common work materials
• Left-hand spiral flutes with right-hand cutting direction for smooth chip evacuation
• Straight-cylindrical shank mounts directly in standard drill chucks and collets
• Bright, uncoated finish suitable for use with cutting fluids on a variety of materials
• 4-flute design balances cutting efficiency with hole finish quality

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and milling machines equipped with drill chucks or collet holders accepting a straight-cylindrical shank of this diameter class.

Installation Notes

Chucking reamers are installed and operated by machinists and toolmakers following standard machine tool practices. Ensure the machine spindle is fully stopped and the chuck or collet is released before inserting or removing the reamer. Secure the shank firmly in the chuck to prevent runout, which can affect hole tolerance and tool life. Always use an appropriate cutting fluid for the work material and operate at recommended reaming speeds, which are typically lower than drilling speeds for the same diameter.
