Hertel 72013451 Chucking Reamer 0.1345 in Hss 4 Flute

Product Description

The HERTEL 72013451 is a chucking reamer designed for precision hole finishing in metalworking and machining applications. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate final sizing of drilled or bored holes. It features a 0.1345-inch cutting diameter, a straight-cylindrical shank for secure chuck mounting, and 4 straight flutes with right-hand cutting direction. Overall length is 3.5 inches with a flute length of 0.875 inches. It is suited for use in drill presses, lathes, and machining centers where controlled, repeatable bore sizing is required.

This chucking reamer is used in job shops, production machining environments, and maintenance settings where close-tolerance hole finishing is needed. The 0.1345-inch diameter falls within the 0.1000 to 0.1499 inch reamer diameter range, making it appropriate for small-bore applications in ferrous and non-ferrous materials. Licensed machinists and tool-and-die professionals typically select this style of reamer when drilling alone cannot hold the required hole tolerance.

Key Features

• 0.1345-inch cutting diameter for precise small-bore finishing
• High-speed steel (HSS) construction for durability across common workpiece materials
• 4 straight flutes with right-hand cutting direction for smooth, accurate material removal
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Bright, uncoated finish suitable for general-purpose reaming operations
• Compact 3.5-inch overall length for use in tight setups

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, CNC machining centers, and manual milling machines equipped with a compatible drill chuck or collet accepting a straight-cylindrical shank in the 0.1345-inch diameter range.

Installation Notes

Chucking reamers are installed and operated by machinists and tool-and-die technicians. Ensure the machine spindle and chuck are fully stopped before inserting or removing the reamer. Secure the straight-cylindrical shank firmly in the chuck or collet to prevent runout, which directly affects hole tolerance. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality.
