Hertel 45676939 Chucking Reamer 0.471 in Solid Carbide

Product Description

The HERTEL 45676939 is a solid carbide chucking reamer designed for precision hole finishing in machine tool applications. With a reamer diameter of 0.471 inches and an overall length of 4 inches, this tool delivers accurate, repeatable bore sizing in a wide range of metalworking operations. The 6-flute straight configuration promotes smooth cutting action and consistent chip evacuation. A bright, uncoated finish is standard. This reamer is intended for use by machinists and tooling professionals working in production or job-shop environments where tight bore tolerances are required.

This chucking reamer is suited for finishing pre-drilled or bored holes to close tolerances in ferrous and non-ferrous materials. The straight shank allows direct chucking in drill presses, CNC machining centers, lathes, or manual milling machines. The 1-3/8 inch flute length provides adequate cutting engagement for through-holes and shallow blind-hole applications within its diameter range. Right-hand cutting direction is standard for conventional spindle rotation.

Key Features

• 0.471 inch reamer diameter for precise hole finishing
• Solid carbide construction for wear resistance and dimensional stability
• 6 straight flutes for smooth cutting action and efficient chip removal
• Straight cylindrical shank for direct chucking in standard toolholders
• Right-hand cutting direction compatible with conventional spindle rotation
• Bright, uncoated finish suitable for general-purpose machining

Compatibility

Designed as a standard chucking reamer for use in drill presses, CNC machining centers, lathes, and milling machines accepting a straight cylindrical shank in the 0.471 inch diameter range.

Installation Notes

Installation should be performed by a qualified machinist following standard machine tool setup procedures. Ensure the spindle is fully stopped and the machine is powered down before mounting or removing the reamer from the toolholder. Verify chuck or collet runout is within acceptable limits before use, as excessive runout will affect bore accuracy and tool life. Follow applicable shop safety standards and the machine manufacturer guidelines for cutting speeds and feeds.
