Hertel 45676301 Chucking Reamer 0.3470 in Solid Carbide

Product Description

The HERTEL 45676301 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 0.3470-inch diameter and six straight flutes, it delivers consistent sizing and smooth surface finishes in through and blind holes. The straight-cylindrical shank allows direct mounting in standard chucks or collets on CNC machining centers, manual mills, and drill presses. The bright, uncoated solid carbide construction provides excellent rigidity and wear resistance across a range of workpiece materials. Licensed machinists and tool-and-die professionals specify this reamer when tight bore tolerances are required in production or job-shop environments.

This reamer is suited for finish-reaming operations in ferrous and non-ferrous metals where hole diameter control falls within the 0.3000 to 0.3499 inch range. Its 1-1/4-inch flute length accommodates typical shallow-to-moderate depth applications. Right-hand cutting direction makes it compatible with conventional spindle rotation on standard machine tools. The straight flute geometry is well matched to through-hole reaming and short blind-hole work where chip evacuation is straightforward.

Key Features

• Solid carbide construction for high rigidity and extended tool life
• 0.3470-inch finished diameter for precise bore sizing
• Six straight flutes for smooth, consistent surface finish
• Bright, uncoated finish — suitable for use with cutting fluids or dry on select materials
• Straight-cylindrical shank for direct chuck or collet mounting
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks and collet holders on CNC machining centers, manual knee mills, and drill presses accepting a straight-cylindrical shank in the 0.3000 to 0.3499 inch diameter range.

Installation Notes

Installation and operation should be performed by qualified machinists following applicable shop safety procedures. Ensure the spindle is fully stopped and locked out before mounting or removing the reamer. Secure the straight shank firmly in a properly sized chuck or collet to prevent runout. Apply appropriate cutting fluid for the workpiece material and avoid excessive feed rates that can cause chatter or tool breakage.
