Hertel 72014350 Chucking Reamer 0.1435 in Hss 4 Flute

Product Description

The HERTEL 72014350 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.1435-inch diameter. Constructed 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 four-flute, right-hand cutting geometry provides smooth stock removal and consistent surface finish. With a 4-inch overall length and a 1-inch flute length, this reamer is well-suited for through-hole and blind-hole finishing operations in production and job-shop environments. A straight-cylindrical shank allows secure clamping in standard drill chucks, collets, and machine tool holders.

This chucking reamer is used in machining operations where hole tolerance and surface finish are critical. Typical applications include sizing holes for dowel pins, bearing bores, and precision fit assemblies. It is installed in drill presses, milling machines, CNC machining centers, and lathes by machinists and toolroom professionals. The 0.1435-inch diameter falls within the 0.1000- to 0.1499-inch reamer diameter range, making it appropriate for small-bore finishing work where accuracy is essential.

Key Features

• Precision 0.1435-inch cutting diameter for tight-tolerance hole finishing
• High-speed steel (HSS) construction for durability across a broad range of workpiece materials
• 4-flute straight-flute geometry for smooth cutting action and consistent surface finish
• Right-hand cutting direction compatible with standard machine spindle rotation
• Bright, uncoated finish suitable for general-purpose reaming applications
• Straight-cylindrical shank fits standard chucks, collets, and holders without adapters

Compatibility

Designed as a general-purpose chucking reamer for use in machine tool setups requiring a 0.1435-inch finished hole diameter with a straight-cylindrical shank interface.

Installation Notes

Chucking reamers are installed by machinists in rotating machine tool spindles. Ensure the machine is powered down and the spindle is fully stopped before loading or removing the reamer. Secure the straight-cylindrical shank firmly in the chuck or collet to prevent runout. Use appropriate cutting fluid for the workpiece material to maximize tool life and hole finish quality.
