Hertel 72308323 Chucking Reamer Size 32 Cobalt Steel

Product Description

The HERTEL 72308323 is a chucking reamer designed for precision hole finishing in metal working applications. Built from cobalt steel with a bright, uncoated finish, this reamer produces accurate, smooth bores to a nominal diameter of 0.1160 inches (Wire Size 32). It features 4 straight flutes with right-hand cutting direction and mounts via a straight-cylindrical shank for use in drill presses, lathes, and CNC machining centers. The overall length is 3.5 inches with a flute length of 0.875 inches. Machinists and tool-room operators rely on cobalt steel construction for improved heat resistance and extended tool life in harder workpiece materials.

This reamer is suited for light-duty finishing operations on through-holes and blind holes in ferrous and non-ferrous metals. It is appropriate for job shop, maintenance, and production environments where tight hole tolerances are required. The straight-cylindrical shank makes it compatible with standard drill chucks and collet holders commonly found on manual and CNC equipment. The 0.1160 inch diameter falls within the 0.1000 to 0.1499 inch decimal range, making it useful for small-diameter precision work in aerospace, automotive, and general metalworking trades.

Key Features

• Wire Size 32 diameter at 0.1160 inches for precision small-bore finishing
• Cobalt steel construction provides improved heat and wear resistance over standard HSS
• 4 straight flutes with right-hand cutting for consistent material removal
• Bright, uncoated finish suitable for use with cutting fluids
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Compact 3.5 inch overall length for use in tight setups

Compatibility

Designed as an OEM-style chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with standard drill chucks or collet holders accepting straight-cylindrical shanks.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer. Secure the straight-cylindrical shank firmly in the chuck or collet to prevent runout during operation. Apply an appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality.
