Hertel 83246751 Chucking Reamer 0.3115 in Solid Carbide

Product Description

The HERTEL 83246751 is a solid carbide chucking reamer designed for precision hole finishing in machine tool applications. With a diameter of 0.3115 inches and a diameter tolerance of 0.0000 to 0.0003 inches, this reamer holds tight sizing accuracy for close-tolerance bores. It is classified as an undersize reamer, making it appropriate where a controlled undersize fit is required. The straight flute geometry and bright uncoated finish make it suitable for a range of common workpiece materials. Six flutes provide a good balance of chip clearance and surface finish quality. Machinists and tool-and-die shops rely on this style of reamer for consistent, repeatable results in production and maintenance environments.

This chucking reamer is intended for use in drilling machines, CNC machining centers, lathes, and similar rotating-spindle equipment. The straight cylindrical shank allows it to be held securely in standard drill chucks or collet-style toolholders. With an overall length of 3.25 inches and a flute length of 1.125 inches, it is sized for moderate-depth through-holes and blind bores in the 0.3000 to 0.3499 inch diameter range. It is well suited to general-purpose machine shop work, tool room applications, and production reaming where dimensional consistency is critical.

Key Features

• Solid carbide construction for hardness and wear resistance in demanding cutting conditions
• 0.3115 inch undersize diameter with a tight tolerance of 0.0000 to 0.0003 inches for precise hole sizing
• Six straight flutes for stable cutting action and good surface finish
• Bright uncoated finish for compatibility with standard cutting fluids and a wide range of materials
• Straight cylindrical shank for use in standard chucks and collet holders without adapter modification
• Right-hand cutting direction, consistent with conventional machine reaming practice

Compatibility

Designed as a standard chucking reamer for use in any rotating-spindle machine tool that accepts a straight cylindrical shank, including drill presses, lathes, and CNC machining centers. Sized within the 0.3000 to 0.3499 inch diameter range.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with reaming operations and machine tool safety. Ensure the spindle is fully stopped and the machine is powered down before mounting or removing the reamer from the toolholder. Use appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Do not use a chucking reamer to remove excessive stock; drill or bore the hole to within a few thousandths of the finished diameter before reaming.
