Hertel 83246694 Chucking Reamer 0.126 in Solid Carbide

Product Description

The HERTEL 83246694 is a solid carbide chucking reamer designed for precision hole finishing in metal workpieces. With a reamer diameter of 0.126 inches and a tight tolerance of 0.0000 to 0.0002 inches over nominal, this tool delivers consistent, accurate bore sizing in production and job-shop environments. The straight flute geometry and bright uncoated carbide construction suit it for use in ferrous and non-ferrous materials where a clean, true finish is required. Machinists and toolroom technicians install this reamer in drill presses, CNC machining centers, and manual mills using standard drill chucks or collet holders.

This reamer is intended for finishing operations where hole diameter control is critical. It is classified as an over-size reamer at 0.1260 inches O/S, making it appropriate for applications requiring a slightly enlarged bore to achieve a press, slip, or locational fit after reaming. The 5/8-inch flute length accommodates shallow through-holes and blind holes in light production runs and maintenance machining. It is well suited to precision work in aerospace, tooling, and general metalworking applications where carbide life and dimensional repeatability matter.

Key Features

• Solid carbide construction for extended tool life and dimensional stability
• 0.126 inches reamer diameter with 0.0000 to 0.0002 inch over-size tolerance
• 4-flute straight flute design for consistent chip evacuation in short-hole applications
• Straight cylindrical shank for easy setup in drill chucks and collet holders
• Right-hand cutting direction, standard for conventional reaming operations
• Bright uncoated finish suitable for a broad range of work materials

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill presses, CNC machining centers, and manual milling machines equipped with a drill chuck or collet system accepting a straight cylindrical shank.

Installation Notes

Installation and operation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer. Secure the straight shank firmly in a drill chuck or collet to the appropriate holding torque for the machine used. Use recommended cutting fluid for the work material to extend tool life and maintain bore finish quality.
