Hertel 72033848 Chucking Reamer 0.3840 in 7 in Oal Hss

Product Description

The HERTEL 72033848 is a straight-flute chucking reamer designed for precision hole finishing in metal machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it holds a nominal diameter of 0.3840 inches and an overall length of 7 inches. The straight-cylindrical shank seats securely in standard drill chucks or collets, and the right-hand cutting direction suits conventional CNC and manual machine tool setups. Machinists and toolroom technicians use this reamer to bring drilled or bored holes to close-tolerance finished dimensions.

This chucking reamer is suited for general-purpose reaming operations in job shops, production machining environments, and toolroom work. It is a standard-size reamer intended for use in ferrous and non-ferrous materials where a bright HSS tool is appropriate. The 1.75-inch flute length accommodates typical through-hole and shallow blind-hole finishing passes at this diameter range. It is not configured as a dowel-pin or over/under-size reamer, making it a direct standard-tolerance fitment tool.

Key Features

• 0.3840-inch finished diameter for close-tolerance hole sizing
• High-speed steel (HSS) construction for durability across a broad range of workpiece materials
• 6 straight flutes for smooth cutting action and consistent surface finish
• Bright, uncoated finish suitable for use with cutting fluids
• Right-hand cutting direction compatible with standard machine tool spindle rotation
• Straight-cylindrical shank fits standard drill chucks and collets without an adapter

Compatibility

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

Installation Notes

A licensed machinist or toolroom technician should install and operate this reamer. Power down and de-energize the machine spindle completely before mounting or removing the tool from the chuck or collet. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not use this reamer to remove excessive stock — pre-drill or bore the hole to within standard reaming allowance before use.
