Hertel 72007354 Chucking Reamer 0.0735 in Hss Straight Flute

Product Description

The HERTEL 72007354 is a high-speed steel (HSS) chucking reamer designed to produce accurate, finished-diameter holes in metalworking applications. With a reamer diameter of 0.0735 inches and an overall length of 3 inches, this tool is built for precision sizing of small-diameter bores. The straight flute geometry and bright, uncoated finish make it well suited for general-purpose reaming in a range of ferrous and non-ferrous materials. It features a straight-cylindrical shank for secure chuck mounting and a right-hand cutting direction. Machinists and tool room operators use this style of reamer to bring pre-drilled holes to exact finished dimensions with tight tolerances.

This chucking reamer is used in machine shop environments, tool rooms, and production lines where consistent hole sizing is critical. The 0.0735-inch diameter falls within the small-bore range, making it appropriate for precision fitting of pins, bushings, and similar components. The 3/4-inch flute length provides adequate chip clearance for the hole depths typically encountered at this diameter. It is designed for use in drill presses, mills, and CNC machining centers with standard chuck toolholding.

Key Features

• 0.0735-inch reamer diameter for precision small-bore finishing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Straight flute design with right-hand cutting direction
• Bright, uncoated finish for general-purpose machining applications
• Straight-cylindrical shank for compatibility with standard chuck toolholding
• 4-flute configuration for balanced cutting and smooth surface finish

Compatibility

Designed as an OEM-style chucking reamer for use in drill presses, vertical mills, and CNC machining centers equipped with standard chuck or collet toolholding systems that accept a straight-cylindrical shank.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with reaming operations. Ensure the spindle and workpiece are fully secured before beginning the cut, and confirm the pre-drilled pilot hole is sized correctly for the reaming stock allowance required. Use appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Never use this tool to remove excess material beyond the intended stock allowance for a reamer of this diameter.
