Hertel 45676855 Chucking Reamer 0.446 in Solid Carbide

Product Description

The HERTEL 45676855 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production environments. With a reamer diameter of 0.446 inches and a 4-inch overall length, it delivers accurate, repeatable bore sizing in a wide range of workpiece materials. The straight flute geometry and bright polished finish reduce cutting friction and promote clean chip evacuation. Six right-hand cutting flutes provide excellent surface finish and dimensional control. This tool is intended for use in CNC machining centers, turret lathes, and drill presses where tight hole tolerances are required.

This chucking reamer is suited for production and job-shop applications requiring consistent hole sizing in metal components. The straight shank allows direct mounting in standard drill chucks, collet chucks, or floating reamer holders. With a 1.375-inch flute length, it is well matched to through-hole and blind-hole applications of moderate depth. It is typically deployed by machinists and toolroom professionals working to close tolerance specifications in ferrous and non-ferrous materials.

Key Features

• Solid carbide construction for extended tool life and rigidity in hard or abrasive materials
• 0.446 inch reamer diameter for precise hole finishing within the 0.4000 to 0.4999 inch range
• Six straight flutes with right-hand cutting direction for smooth, accurate bore sizing
• Bright polished finish reduces built-up edge and improves surface finish quality
• Straight shank for compatibility with standard chucks and collet systems
• 4 inch overall length with 1.375 inch flute length suits a range of workpiece depths

Compatibility

Designed as a standard chucking reamer for use in CNC machining centers, turret lathes, and drill presses equipped with drill chucks, collet chucks, or floating reamer holders accepting a straight shank tool.

Installation Notes

This tool should be installed by a qualified machinist following standard toolroom practices. Secure the straight shank firmly in a properly sized chuck or collet before operation and verify runout with a dial indicator before cutting. Always apply appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish. Inspect the cutting edges before each use and remove the tool from service if chipping or wear is detected.
