Hertel 72033228 Chucking Reamer 0.3220 in Hss Straight Flute

Product Description

The HERTEL 72033228 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, this reamer maintains tight diameter tolerances at 0.3220 inches for consistent, accurate bores. The straight-cylindrical shank seats securely in standard drill chucks or collet holders, making it a reliable choice for CNC machining centers, lathes, and drill presses. With a 6-flute configuration and right-hand cutting direction, it removes material efficiently while producing a smooth bore finish. Machinists and toolroom professionals install this type of reamer as a finishing pass after drilling or boring to achieve final size.

This chucking reamer is suited for general-purpose reaming in ferrous and non-ferrous metals in both job shop and production environments. The 1.5-inch flute length is appropriate for shallow to moderate-depth bores, and the 6-inch overall length provides adequate reach for most standard workholding setups. It is commonly used in manual machining operations as well as automated tool-change applications where a consistent, repeatable finishing tool is required.

Key Features

• 0.3220-inch reamer diameter for precise bore finishing within the 0.3000 to 0.3499 inch diameter range class
• 6-flute straight design delivers smooth surface finish and even cutting load distribution
• High-speed steel (HSS) construction provides durability across a range of workpiece materials
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank for reliable grip in drill chucks and collet holders
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed as a standard chucking reamer for use in drill chucks, collet holders, and floating reamer holders on drill presses, lathes, and CNC machining centers accepting a straight-cylindrical shank tooling.

Installation Notes

Installation and use should be performed by qualified machinists familiar with reaming operations and proper speeds and feeds for HSS tooling. Ensure the workpiece is securely clamped and the spindle is at a full stop before loading or unloading the tool. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Never use a reamer to remove more stock than the tool geometry is rated for — pre-drill or bore to within the recommended allowance before reaming to final size.
