Hertel 45676103 Chucking Reamer 0.325 in Solid Carbide

Product Description

The HERTEL 45676103 is a solid carbide chucking reamer designed for precision hole finishing in metalworking applications. It measures 0.325 inches in diameter with a 3.5 inch overall length and a 1.25 inch straight flute length. The 6-flute, right-hand cutting geometry delivers a smooth, accurate bore by removing minimal material on the final pass. Solid carbide construction provides the rigidity and wear resistance needed when reaming hardened or abrasive materials. The bright, polished finish reduces friction and helps with chip evacuation. A straight shank allows direct mounting in standard drill chucks, collet chucks, and floating holders.

This reamer is suited for machine shop and production floor environments where consistent, tight-tolerance hole sizing is required. It is typically used in CNC machining centers, knee mills, and drill presses for finishing pre-drilled or bored holes to a precise 0.325 inch diameter. Applications include fixture plates, jig components, and any workpiece where a smooth bore finish and accurate diameter are critical to assembly. A licensed machinist or toolroom operator is the expected installer and user.

Key Features

• 0.325 inch diameter in the 0.3000 to 0.3499 inch range for precise hole sizing
• Solid carbide construction for rigidity and extended tool life in hard or abrasive materials
• 6-flute geometry for smooth cutting action and improved surface finish
• Right-hand cutting direction compatible with standard spindle rotation
• Bright polished finish reduces friction and aids chip clearance
• Straight shank fits standard drill chucks and collet holders

Compatibility

Designed as an OEM-style chucking reamer for use in standard straight-shank tool holders on CNC machining centers, knee mills, and drill presses requiring a 0.325 inch finished bore diameter.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician. Secure the straight shank firmly in a drill chuck, collet chuck, or floating reamer holder before running the spindle. Always pre-drill or bore the hole to the correct undersize before reaming, and apply appropriate cutting fluid to extend tool life and improve surface finish. Inspect the reamer for chipping or wear before each use, as carbide tooling can fracture if run in a damaged condition.
