Hertel 72009103 Chucking Reamer 0.0910 in Hss 4 Flute

Product Description

The HERTEL 72009103 is a straight-flute chucking reamer designed for precision hole finishing in metal working applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent sizing and surface finish in drilled or bored holes. It measures 0.0910 inches in diameter with a 3-inch overall length and a 3/4-inch flute length. The straight-cylindrical shank makes it compatible with standard drill chucks and collet holders. With four flutes and right-hand cutting direction, it is well suited for machine reaming operations requiring accurate hole tolerances in production or maintenance environments.

This reamer is intended for machine shop, toolroom, and maintenance applications where precise hole sizing in the 0.0500 to 0.0999 inch diameter range is required. It is typically used in CNC machining centers, drill presses, and turret lathes. Common applications include finishing holes in ferrous and non-ferrous metals where tight dimensional tolerances and smooth bore finishes are critical. Machinists, tool and die makers, and maintenance technicians working on small-diameter precision holes will find this reamer appropriate for their setups.

Key Features

• 0.0910 inch reamer diameter for precision small-bore hole finishing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Bright, uncoated finish for general-purpose metal cutting
• 4-flute straight design provides stable cutting action and consistent chip evacuation
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank fits standard drill chucks and collet systems

Compatibility

Designed as an OEM-style machine reamer for use in standard drill chucks and collet holders accepting a straight-cylindrical shank in the 0.0500 to 0.0999 inch diameter range.

Installation Notes

This reamer is installed by machinists and tool and die professionals in machine tool spindles using an appropriate chuck or collet. Always secure the shank fully in the holding device before operation and confirm spindle speed and feed rate are appropriate for the workpiece material and reamer diameter. Power down and lock out the machine before changing or inspecting the tool. Use cutting fluid appropriate for the workpiece material to extend tool life and improve surface finish.
