Hertel 72009707 Chucking Reamer 0.097 in Hss 4 Flute

Product Description

The HERTEL 72009707 is a high-speed steel (HSS) chucking reamer designed to bring bored or drilled holes to precise finished diameters. With a cutting diameter of 0.0970 inches and an overall length of 3-1/2 inches, this reamer is built for close-tolerance finish work in metal, where hole quality and dimensional accuracy are critical. The bright, uncoated HSS construction provides reliable performance across a range of workpiece materials. Four straight flutes and a right-hand cutting direction deliver smooth material removal and clean hole walls. The straight-cylindrical shank allows secure seating in standard drill chucks and collet holders.

This reamer is suited for machine-shop and production environments where small-diameter precision holes are required. The 0.0970-inch diameter falls within the smaller end of the standard chucking reamer range, making it appropriate for applications such as pin bores, pilot holes, and close-tolerance fits in light-gauge metal components. It is typically run in a drill press, CNC machining center, or manual mill. Machinists, toolroom technicians, and production operators install and run this tool as part of standard hole-finishing operations.

Key Features

• 0.0970-inch cutting diameter for small-bore precision finishing
• HSS tool material with bright, uncoated finish for general-purpose metal cutting
• Four straight flutes for smooth, consistent material removal
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank for secure chuck or collet mounting
• 7/8-inch flute length provides sufficient engagement depth for typical small-bore applications

Compatibility

Designed as a standard chucking reamer for use in drill presses, CNC machining centers, manual mills, and similar machine tool setups that accept straight-cylindrical shank tooling.

Installation Notes

Chucking reamers are installed by machinists and toolroom technicians; always power down and lock out the machine spindle before changing tooling. Seat the straight-cylindrical shank fully and securely in the chuck or collet before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole-surface finish. Never use a reamer to remove excessive stock — pre-drill or bore the hole to within a few thousandths of final diameter before reaming.
