Hertel 72033657 Chucking Reamer 0.365 in Hss 6 Flute Rh

Product Description

The HERTEL 72033657 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metal machining applications. With a 0.3650-inch diameter and a 7-inch overall length, this reamer delivers accurate, consistent bore sizing in drilling and turning operations. The straight flute geometry and bright, uncoated finish make it well-suited for finishing softer metals and materials where chip evacuation is straightforward. Machining professionals and tool-room technicians use this style of reamer to bring pre-drilled holes to precise dimensional tolerance. At 0.19 pounds, it is lightweight and easy to handle in a standard drill chuck or CNC toolholder.

This chucking reamer is applied in general-purpose metal machining where a final-pass reaming operation is needed to achieve accurate hole diameter and surface finish. The straight-cylindrical shank allows direct clamping in drill chucks, collet chucks, or machine spindles without adapters. With a 1.75-inch flute length and right-hand cutting direction, it is intended for through-hole and shallow blind-hole reaming in a drill press, lathe, or CNC machining center. It is not configured as a dowel pin reamer or an over/under-size reamer, making it a standard production or maintenance-shop tool.

Key Features

• 0.3650-inch reamer diameter for precise bore sizing in the 0.3500 to 0.3999-inch range
• HSS tool material provides good toughness and wear resistance for general machining
• 6 straight flutes promote even cutting load and smooth surface finish
• Bright/uncoated finish suits use on softer metals and standard cutting fluids
• Straight-cylindrical shank fits standard drill chucks and collet toolholders without adapters
• Right-hand cutting direction compatible with conventional machine spindle rotation

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with drill chucks or collet chucks that accept a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and changed by qualified machinists or toolroom technicians. Always de-energize and lock out the machine spindle before mounting 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 promote tool life and achieve the intended surface finish.
