Hertel 72034606 Chucking Reamer 0.4600 in Hss 6 Flute

Product Description

The HERTEL 72034606 is a straight-flute chucking reamer designed for precision hole finishing in metal and similar materials. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing in a wide range of machine tool applications. The 0.4600-inch diameter reamer features six flutes and a right-hand cutting direction, making it a standard choice for achieving tight tolerances in drilled or bored holes. With a 7-inch overall length and a 1.75-inch flute length, it fits conventional drill presses, lathes, and CNC machining centers using a straight-cylindrical shank. Machinists and toolroom technicians reach for this style of reamer when dimensional accuracy and smooth surface finish are required.

This chucking reamer is suited for general machining environments where a 0.4600-inch finished hole is required. The straight-cylindrical shank seats securely in a drill chuck or collet, allowing use on a variety of machine setups including drill presses, turret lathes, and vertical machining centers. It is appropriate for production and job-shop use where repeatable, accurate hole sizing is needed in ferrous and non-ferrous workpieces. The bright HSS construction makes it a cost-effective option for moderate-volume applications that do not require coated tooling.

Key Features

• 0.4600-inch reamer diameter for precise hole finishing within the 0.4000 to 0.4999-inch range
• High-speed steel (HSS) construction for durability across a broad range of workpiece materials
• Bright, uncoated finish suited for general-purpose machining applications
• Six straight flutes with right-hand cutting direction for smooth, consistent material removal
• Straight-cylindrical shank compatible with standard drill chucks and collets
• 7-inch overall length with 1.75-inch flute length for reach in standard machine setups

Compatibility

Designed as a standard chucking reamer for use in machine tools that accept a straight-cylindrical shank, including drill presses, lathes, and machining centers requiring a 0.4600-inch finished hole diameter.

Installation Notes

This reamer is installed by a machinist or toolroom technician into a drill chuck or collet that matches the straight-cylindrical shank diameter. Ensure the machine spindle is fully stopped and de-energized before mounting or removing the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Always pre-drill or bore the hole close to final size before reaming to avoid excessive tool load.
