Hertel 45675238 Chucking Reamer 0.206 in Solid Carbide

Product Description

The HERTEL 45675238 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 0.206 inch diameter and a 3 inch overall length, this reamer delivers tight dimensional accuracy suitable for close-tolerance bores. The bright polished finish reduces friction and aids in chip evacuation during the cutting process. A 4-flute, straight-flute geometry with right-hand cutting direction provides smooth, consistent material removal. Machining professionals and toolroom technicians use this tool in CNC machining centers, drill presses, and manual lathes where repeatable bore sizing is critical.

This chucking reamer is suited for production and job-shop environments requiring precise hole finishing in ferrous and non-ferrous materials. The straight shank allows direct mounting in standard drill chucks, collet chucks, and floating reamer holders. With a 1 inch flute length, it is optimized for shallow-to-moderate depth reaming operations. It is commonly used in aerospace, automotive, and general precision machining where final bore diameter control is essential.

Key Features

• Solid carbide construction for wear resistance and extended tool life in hard or abrasive materials
• 0.206 inch diameter within the 0.2000 to 0.2499 inch decimal range for precision hole sizing
• 4-flute straight-flute design with right-hand cutting direction for smooth, controlled material removal
• Bright polished finish reduces built-up edge and improves surface finish in the bored hole
• Straight shank compatible with standard chucks and collet holders
• 3 inch overall length with 1 inch flute length suited for shallow reaming operations

Compatibility

Designed as a standard straight-shank chucking reamer for use in CNC machining centers, drill presses, and lathes equipped with drill chucks or collet chuck systems accepting a 0.206 inch diameter straight-shank tool.

Installation Notes

This reamer is installed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before mounting. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Verify bore pre-drill diameter leaves adequate stock for reaming — typically 0.005 to 0.015 inches of material removal is standard practice, though confirm with your process requirements rather than relying solely on general guidance.
